For those considering renovation of used properties and vacant houses in Tama-ku
I bought a used property, but I’m not sure if the renovation estimate I received is reasonable.
This is my first full renovation, and I’m worried about making mistakes.
I want to make the most of subsidies and grants.
For such concerns, Kakeru Koumuten Co., Ltd., which has numerous achievements close to Tama Ward, will clearly explain the key points for a successful renovation.
Obtain estimates from at least 3 companies!
01Reasons for the Increase in Renovations of Used Properties and Vacant Houses in Tama Ward
Tama Ward in Kawasaki City is a district blessed with the Odakyu Line and Nambu Line running through Noborito, Mukogaoka-Yuen, and Ikuta, surrounded by the Tama Hills and the Tama River. It features the rich nature of Ikuta Ryokuchi and serves as an educational city with universities.
The residential areas from the Showa era, which spread across the hills, are now entering a period of generational change as they reach 40 to 50 years old. This is why the option of “buying a used house and renovating it to suit one’s lifestyle” is expanding in Tama Ward.
Convenience and Nature of Noborito and Ikuta
With the Odakyu and Nambu lines providing good access to the city center, and the nature of Ikuta Ryokuchi nearby, there is an active movement to live on through used properties and renovations.
Slopes and Retaining Walls of the Tama Hills
Residential areas on hills like Ikuta and Nishi-Ikuta have elevation differences, requiring checks on retaining walls, slopes, drainage, and considerations for scaffolding and delivery.
Considerations for Locations Along the Tama River
In locations close to the Tamagawa River, such as Noborito and Nakano-shima, it is recommended to check the hazard map and consider flood prevention measures as necessary.
Be Aware of the “Boundary” of New Earthquake Resistance Standards
The earthquake resistance of used houses varies significantly depending on the construction period. It is important to determine whether the house was built before the standard revisions in 1981 and 2000.
This article summarizes the reasons, points to consider, cost averages, the latest subsidies for 2026, and how to choose a contractor from the perspective of Kakeru Koumuten, which also serves the Tama Ward, for those considering renovating used properties or vacant houses without “failure.”
The Most Important Thing is “Comparative Estimates”
To avoid failure in renovations, the most crucial step is comparative estimates. First, obtain estimates from at least three companies that operate in the Tama Ward. Our company, Kakeru Koumuten Co., Ltd., also receives many consultations and requests for renovations of vacant houses and used properties.
02Reasons for Renovating Vacant Houses and Used Properties
In recent years, the Japanese housing market has expanded options not only for new constructions but also for utilizing used properties through renovations. There is a growing interest in living by purchasing and renovating used houses. Here, we explain the typical reasons for renovating vacant houses and used properties.
Reason 1 To Live Comfortably as Your Own Home
The most common reason for purchasing and renovating a used property is “to live comfortably.” Older houses often have issues with the roof, exterior walls, and plumbing, making them less livable as they are. By renovating and upgrading the facilities and interiors, you can create a comfortable living environment. Additionally, by changing the layout and refreshing the interior, you can finish your home to suit your family’s lifestyle while keeping costs lower than new construction.
Reason 2 To Increase Asset Value for Sale
More people are purchasing and renovating used properties with the intention of selling them. Used houses are often valued low as they are, but renovations can enhance their appearance and performance, thereby increasing their value as properties.
Reason 3 To Utilize as Investment or Business
For purchases made for investment or business purposes, renovations are essential. By transforming them into stylish rentals or share houses, you can differentiate them from other properties, and depending on the location and planning, you can also expect improved profitability. Initial costs can be lower than new constructions, and depending on the use and conditions, there may be subsidies or tax incentives available, leading to an increase in those utilizing vacant houses for business.
03Points to Consider When Renovating Vacant Houses and Used Properties
Point 1 Choose a Reliable Construction Company
First and foremost, it is essential to select a contractor you can trust to handle your renovation. Since used properties have had previous occupants, the internal structure and condition are often not clear until you actually see them. Choose a contractor who can carry out the work properly according to your wishes, the structure of the house, and the surrounding environment, and who also provides aftercare following the construction.
Point 2 Always Check the Deterioration of the Building
For used properties and vacant houses, it is crucial to check which parts have deteriorated and to what extent beforehand. Since the property has been lived in by someone else, internal damage is often not apparent without investigation. Conduct a current condition survey before starting work to identify hidden deterioration.
Point 3 Review Earthquake Resistance and Insulation Performance
Particularly important in the renovation of used and vacant houses is the review of earthquake resistance and insulation. The earthquake resistance standards were significantly revised in 1981, and homes built before that may not meet current standards. Furthermore, in 2000, regulations regarding joints and foundations were strengthened, making older buildings more likely to lack earthquake resistance. Check the condition of the building before starting work and be sure to check the earthquake resistance and insulation.
Point 4 Check Subsidy Programs and Renovation Tax Deductions
To keep construction costs down, it is important to check for subsidies and renovation tax deductions. Subsidies are provided by the national and local governments, and part of the costs for earthquake retrofitting, energy-saving construction, and barrier-free renovations may be supported. Tax deductions include the “housing loan tax deduction” when using a mortgage, and there are systems that allow for deductions on certain construction costs even with personal funds. These can sometimes be used together, so it is essential to check in advance and plan to utilize them strategically for a successful renovation (for the latest information, see this subsidy section).

05[Latest in 2026] Subsidies and Grants Available in Tama Ward
One way to renovate used properties and vacant houses cost-effectively is by utilizing the subsidy and grant system. As of 2026, we have summarized the main systems that residents of Tama Ward may be able to use.
*The following information is as of September 3, 2026. The content, duration, and budget of the systems change annually, and many will end once the budget limit is reached. Please check for the latest information with our company or each contact point before applying. Kakeru Koumuten can assist with confirming the systems and necessary documents, but the applicant and application method may vary depending on the system.
National Program: Housing Energy Saving 2026 Campaign
The government is implementing multiple subsidy projects targeting energy-saving renovations under the “Housing Energy Saving 2026 Campaign.” Construction for insulation, windows, and water heaters may be eligible for these subsidies.
This program is a successor to the “Child-Rearing Green Housing Support Project.” In principle, it requires renovation work that includes insulation improvements for openings (windows) and the building structure, and is applicable to eco-friendly housing equipment, child-rearing compatible renovations, disaster prevention enhancements, and barrier-free renovations.
Subsidy upper limit guidelines: For buildings constructed before 1991, up to 1,000,000 yen per unit (50,000 yen depending on the work content); for buildings constructed between 1992 and 2016, up to 800,000 yen per unit (400,000 yen for the same). Eligible construction must start after November 28, 2025, and applications are accepted starting June 30, 2026. Reservations must be made by November 16 at the latest, and grant applications must be submitted by December 31 at the latest (early termination may occur if the budget limit is reached). Applications must be made through registered contractors.
This program covers insulation renovations for windows, including the installation of interior windows, replacement of exterior windows, and glass replacement. The subsidy amount is substantial and effective for addressing cold, heat, and condensation issues. It can easily enhance the insulation performance of existing homes.
The subsidy amount varies based on the window method, performance, size, and construction style of the house. If the total subsidy amount for one application is less than 50,000 yen, it is not eligible. Applications have been accepted since March 31, 2026, and grant applications must be submitted by December 31 at the latest (early termination may occur if the budget limit is reached). Applications must be made through registered contractors.
This program targets the replacement of water heaters with high-efficiency models such as EcoCute, hybrid water heaters, and EneFarm. It is well-suited for older properties planning to replace their water heaters.
Subsidy amount guidelines: EcoCute 70,000 to 100,000 yen per unit, hybrid water heaters 100,000 to 120,000 yen per unit, EneFarm 170,000 yen per unit. Eligible construction must start after November 28, 2025, and applications are accepted starting March 31, 2026 (early termination may occur if the budget limit is reached).
Kawasaki City Program
This is the main program for reinforcing old wooden houses against earthquakes. It is effective for earthquake resistance renovations combined with the purchase of existing wooden houses. Dispatch of earthquake diagnosis specialists is available for free.
Building-wide renovations: General households up to 1.3 million yen / Non-taxable households up to 1.8 million yen (subsidy rate 4/5). Partial renovations: General 1 million yen / Non-taxable 1.35 million yen. Eligible properties are wooden two-story houses built using traditional framing methods that commenced construction before May 31, 2000. From April 2026 (Reiwa 8), the scope has been expanded to include wooden structures built under new seismic standards (up to May 2000). Please confirm the application period and budget status as they may change (Contact: City Planning Bureau). For more details, visit the official Kawasaki City page.
This program is for individuals aged 65 and older who have been certified as requiring support or higher. Renovations of bathrooms, entrances, hallways, stairs, etc., that are “not covered” by nursing care insurance are eligible, and it is also useful when utilizing second-hand houses for multi-generational living.
Standard limit amount is 1 million yen. The user burden rate is set in seven tiers according to income. Pre-consultation before starting construction is mandatory (applications after construction has started are not eligible). For more details, visit the official Kawasaki City page.
This program is for individuals certified as requiring support or nursing care. Eligible renovations include the installation of handrails, elimination of steps, changes to flooring materials, and replacement of doors and toilets.
Out of the payment limit standard amount of 200,000 yen, those with a 10% burden will receive 90% (up to 180,000 yen). There may be cases of 20% or 30% burden depending on income. Pre-application before starting construction is required.
This city program is for those looking to install solar power and storage batteries in conjunction with the renovation of used properties. There are also subsidies for ZEH (Net Zero Energy House) conversion.
Main guidelines: Solar power (not subject to FIT) 70,000 yen/kW, maximum 280,000 yen; storage batteries 100,000 yen/kWh, maximum 700,000 yen; ZEH/ZEH Oriented 250,000 yen/unit; ZEH+ 400,000 yen/unit. Applications for fiscal year 2026 are being accepted from April 24 to December 28 (until the budget is reached). For more details, visit the official Kawasaki City page.
* In Kawasaki City, there are no city-specific subsidies for general renovations such as exterior wall painting or roof repairs, nor for insulation improvements themselves. For insulation and window work, it is essential to utilize the national “Housing Energy Efficiency 2026 Campaign” mentioned above.
View information on renovation tax reductions and other systems
- Housing Loan Tax Reduction: If you use a housing loan for renovations that meet certain requirements, income tax and other deductions will be applied based on the year-end balance.
- Renovation Promotion Tax System (Investment-type Tax Reduction): For construction related to earthquake resistance, energy conservation, barrier-free access, and long-term excellent housing, there may be cases where income tax deductions can be received even with personal funds.
- Reduction of Fixed Asset Tax: There is a system that reduces fixed asset tax for a certain period for earthquake resistance renovations, energy conservation renovations, and barrier-free renovations.
- Kanagawa Prefecture Existing Housing Energy Efficiency Renovation Subsidy: For the fiscal year 2026, the subsidy rate is 1/3 with a maximum of 150,000 yen. The first phase has ended, but additional applications are scheduled to be accepted from September 7 to September 30, 2026, only via electronic application, on a first-come, first-served basis (approximately 25 cases). Applicants must apply themselves, and construction before the grant decision is not eligible. Please check the official page of Kanagawa Prefecture.
While subsidies and tax reductions can sometimes be combined, there are restrictions on overlapping for the same construction. Kakeru Koumuten will organize and propose which systems can be used for your construction after conducting a site survey.

07How to Choose a Renovation Contractor for Used Properties and Vacant Houses in Aoba-ku
There are many renovation companies that serve Aoba-ku, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following five points.
- Experience in renovation work
- Check for warranties and after-sales maintenance
- Obtain estimates from multiple contractors (at least 3 companies)
- Confirm whether they perform renovations in-house
- Check if they offer color simulations and perspective drawings
1. Experience in renovation work
Many renovation contractors publish their work achievements on their websites. If a contractor provides detailed explanations of the process with photos, it makes it easier to visualize the outcome after the request, giving you peace of mind. If you’re feeling uncertain, choose a contractor with ample experience.
Google and review sites can also be helpful. It’s important to check the content of low ratings, the company’s responses, and the timing of the posts. In particular, Google reviews can be informative, but don’t make your decision based solely on reviews; consider the work achievements, estimates, and warranty details for a comprehensive assessment.
2. Confirm the presence of warranties and aftercare services
When selecting a contractor, be sure to check for warranties. If repairs are needed within the warranty period, they may be done for free. The duration varies by contractor and paint type, but typically ranges from 1 to 10 years (emergency repairs and partial repairs are often not covered). Some contractors also provide aftercare services, so be sure to check for those as well.
Kakeru Koumuten Co., Ltd. guarantees warranties for exterior renovations and sealing work. We also conduct aftercare services, sending out annual notification DM to ensure annual inspections are possible.

3. Obtain estimates from multiple contractors (at least 3 companies)
When requesting renovations, be sure to obtain estimates from multiple contractors. Even for the same work, warranties, aftercare services, and costs can vary significantly. Having multiple estimates makes price negotiations easier.
When comparing estimates, it’s important to look at not just the costs, but also the “items in the estimate,” “verification of undercoating materials, sealing materials, and auxiliary paint,” and “confirmation of the process.” Lowering the rank of auxiliary parts or skipping steps can reduce costs, so it’s crucial to not make decisions based solely on price.
See detailed points for comparing estimates
4. Confirm whether the company conducts renovations in-house
At Kakeru Koumuten Co., Ltd., we conduct detailed hearings and surveys regarding the existing “condition,” “location,” “materials,” “desired durability,” and “design” to propose the optimal plan. While there is nothing inherently wrong with a system where a partner company performs the construction, it is important to confirm whether the contracted company understands the construction details and clearly defines the responsibilities for quality control and guarantees. With in-house construction, it is easier to coordinate with the site, allowing for quick responses in case of any troubles.
5. Do they support color simulations and perspective drawings?
Choosing colors and envisioning the appearance after construction can be challenging for both exterior and interior projects. With simulations, you can reduce the risk of mistakes like “it looked different than I imagined.” Since it is difficult to redo once construction is done, it is advisable to choose a company that can accommodate flexible simulations.
08Reasons why Kakeru Koumuten is chosen for remodeling used houses in Tama-ku
One reason is that “Kakeru Koumuten is also close to Tama-ku,” but
we have “initiatives in remodeling vacant houses and used properties that cannot be imitated by other companies,”
which has received high praise from many customers.
We have absolute confidence in “cost,” “quality,” and “plans” for remodeling in Tama-ku. Please compare our estimates with those from other companies.
The most important aspect of remodeling is getting multiple estimates. Be sure to request estimates from at least three companies that operate in Tama-ku!
1. Equipment specialized for in-house remodeling
At Kakeru Koumuten Co., Ltd., we have organized warehouses and material storage to provide high-quality remodeling at low costs. We have five bases located in Kanagawa and Tokyo, including Aoba-ku, Yokohama and Machida City, Tokyo.
In-house scaffolding materials
For exterior renovations, we can construct temporary scaffolding using our own scaffolding materials and in-house scaffolding team. By not outsourcing, this leads to cost savings on scaffolding work. We own scaffolding materials for approximately 50 detached houses.
Materials stored in our large in-house warehouse
We store roofing materials and paints. By placing large orders at once, we can procure materials at lower prices, and since we always have stock available, we can respond quickly in emergencies. We are also equipped with various tools to handle different types of construction, such as compressors and cleaning machines.
In-house waste separation
In exterior renovations, various waste materials such as paint, wood, and metal are generated. Our company is committed to separating and recycling waste materials, working towards reducing waste and minimizing disposal costs.
Showroom dedicated to exterior renovations
In the showroom, you can not only have meetings but also check the actual paint colors and a wide variety of catalogs. You can also confirm heat insulation properties using a heat insulation paint testing machine and color simulation. The showroom is a 3-minute walk from Eda Station in Aoba-ku, Yokohama. It is also easily accessible from Kawasaki City.
2. In-house Construction Focused on Exterior Work
A major strength of Kakeru Koumuten is our in-house construction focused on exterior work. By maintaining a consistent system from inquiry to project completion, we aim to provide high-quality renovations at reduced costs. Since one representative handles everything from the estimate to project completion, communication is smooth without changes in sales or construction management. We carry out construction with our own craftsmen, from temporary scaffolding setup to exterior wall painting and roof renovations. We are confident in our plans and costs, so we welcome competitive estimates.
3. Various Permits and Skilled Workers
We have obtained construction industry licenses as well as permits for industrial waste collection and transportation. We also have nationally certified sheet metal workers and painting specialists, ensuring confidence in our construction techniques. We are capable of handling large-scale painting projects for factories and apartment complexes.
4. Warranty and Aftercare
Exterior painting and joint sealing work come with a warranty. Aftercare is available every year, and we send out notification DM each year. If you have concerns about the warranty, please click the image above for more information.
5. Flexible and Prompt Response
We are equipped to handle various exterior troubles and situations. If you cannot access the roof at height, we can respond using a drone. We also use a thermal imaging camera for leak investigations. We respond according to our customers’ wishes and also accept emergency measures for sudden leaks only.
6. Human Resource Development
We create various models for skill improvement and conduct practical training. Since exterior renovations vary in construction methods and materials based on existing materials and shapes, we conduct regular technical training to ensure each staff member can handle various sites.

7. Flexible Simulations for Both Exterior and Interior!
Kakeru Koumuten is dedicated to helping you choose colors and designs for your important building renovations, both exterior and interior, to ensure your satisfaction.
7-1. Exterior Renovation Simulation
We can create color simulations for exterior wall painting, as well as simulations for metal siding and roof overlays. We can create simulations from actual photos of your building and propose several patterns with our recommended color schemes. We also accommodate “test painting” and “arranging paint boards” to confirm the actual colors.
7-2. Interior Renovation Simulation
We also support simulations and perspective drawings for interior renovations. Based on your preferred image, such as a modern style, we will propose recommended simulations. We create realistic perspectives from actual floor plans.
8. Solar Panel and Storage Battery Installation Work Available!
More customers are introducing solar power systems, which have substantial subsidies, in conjunction with renovations of used properties. Kakeru Koumuten Co., Ltd. also handles solar power system installations and will propose solar panels tailored to the shape of your roof. We can also accept requests for estimates and power generation simulations only.
09Renovation of Used Properties and Vacant Houses in Tama-ku | Frequently Asked Questions
We will answer the most frequently asked questions from those considering renovations of used properties and vacant houses in Tama-ku.
Is it better to renovate after buying a used property or consult before purchasing?
If possible, please consult us before making a purchase decision. Used properties often have deterioration that is not visible, and it is not uncommon to encounter cases where “unexpected construction costs arose” after purchase. By having Kakeru Koumuten Co., Ltd. check the condition of the property you are considering in advance and provide an estimate of necessary renovations, you can establish a feasible financial plan.
What renovations should be prioritized for a used detached house in Tama-ku?
It depends on the condition of the building, but we prioritize areas that, if left unattended, could lead to further damage, such as leaks, termites, structure, and seismic resistance. After that, we will decide the order of exterior renovations such as roofs and walls, water areas (kitchen, bathroom, toilet), and insulation based on your budget and impact on your daily life. In residential areas along the Odakyu and Nambu lines, roofs and walls often reach the end of their lifespan first, so we recommend starting with a comprehensive inspection of the entire building, including the exterior.
Tama-ku is close to hills and the Tama River; what should I be aware of regarding used detached houses?
Tama-ku features residential areas on the slopes of the Tama Hills such as Ikuta and Nishi-Ikuta, as well as lowlands along the Tamagawa River, including Noborito and Nakanojima. In hilly locations, it is advisable to check retaining walls, slopes, and drainage, while in lowland areas along the river, reviewing hazard maps and considering flood prevention measures is recommended. Many single-family homes from the Showa era are due for exterior updates, so we suggest starting with inspections for exterior and seismic resistance. We also propose the Kawasaki City seismic retrofitting subsidy (general maximum of 1.3 million yen, subsidy rate of 4/5).
How much does a full renovation (full reform) cost?
The cost of a full renovation for a single-family home varies significantly depending on the scope and quality. If focusing on partial renovations, it typically starts from around 5 million yen, while large-scale renovations that include interior and exterior work, plumbing, insulation, and seismic upgrades can exceed 10 million to 20 million yen. We will first conduct a site survey to assess the condition and propose a prioritized plan that fits your budget.
Do I need to apply for subsidies myself? Is the process difficult?
The applicant varies depending on the program. For example, the national “Mirai Eco Housing 2026 Project” requires registered contractors (construction companies) to apply. For seismic retrofitting or home modifications under long-term care insurance in your municipality, the application is generally made by the homeowner, but we will guide you through the necessary documents and process. We will organize and inform you about “which programs are available,” so please feel free to consult with us first.
What risks are there if I leave a vacant house unattended?
Risks include the progression of water leaks and termite damage, depreciation of asset value due to deterioration of exterior walls and roofs, and neglect of garden trees and equipment. Additionally, if you receive a recommendation from the municipality as a “poorly managed vacant house” or “designated vacant house,” there is a possibility that the property tax exemption for residential land will be revoked. Early inspections and necessary repairs aligned with your plans to live in, rent, sell, or utilize the property can ultimately help reduce costs.
I am concerned about seismic resistance. How can I assess the seismic safety of a used single-family home?
The construction date is a significant indicator. Check if it was built after June 1981 (new seismic standards), and further if it was built after June 2000 (strengthening of joint and foundation regulations). For wooden houses built before this, we recommend a seismic diagnosis. Your municipality also offers subsidies for seismic retrofitting of wooden houses, which can significantly reduce costs if eligible (for details, see the subsidy section above). Kakeru Koumuten Co., Ltd. can assist you from diagnosis to renovation.
Will I need temporary housing during construction? How long will it take?
This depends on the scope of the work. Exterior renovations and partial interior work can often be done while you remain in your home, but for large-scale full renovations that include plumbing, we may recommend temporary housing. The estimated duration is about 2 to 4 weeks for exterior work and approximately 1 to 3 months or more for full renovations. We will provide a schedule in advance and propose a plan that minimizes the impact on your daily life.
Is Tama-ku within your service area? Will there be travel costs?
Yes, Tama-ku is within the service area of Kakeru Koumuten Co., Ltd. Our headquarters is located in Aoba-ku, Yokohama, and we have five bases in Kanagawa and Tokyo, covering the entire area of both prefectures. Estimates are completely free, and we do not engage in persistent sales tactics. Please feel free to consult with us first.

10Features of Tama-ku
Tama-ku in Kawasaki City is blessed with the Tama Hills and the Tama River, centered around Noborito, Mukogaoka-Yuen, and Ikuta, with the Odakyu Line and Nambu Line running through it. It boasts rich nature in Ikuta Ryokuchi and serves as an educational city with universities.
The Showa-era residential areas sprawling across the hills are undergoing generational changes, and the choice of living on through used properties plus renovations is becoming established. Kakeru Koumuten has its headquarters in Aoba-ku, Yokohama, and widely accepts requests for exterior and interior renovations throughout Kawasaki City. We can handle exterior construction, including roof and wall overlay methods, with in-house construction.
Areas Available for Renovation
Kakeru Koumuten accepts requests across all of Kanagawa and Tokyo prefectures.
