For those considering renovations of used properties and vacant houses in Edogawa-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 a track record of exterior renovations in Edogawa-ku, 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 Edogawa-ku
Edogawa-ku, Tokyo, is located at the eastern edge of the 23 wards, nestled between the Arakawa and Edogawa rivers, with a population of approximately 697,000. Areas like Kasai, Koiwa, and Ichinoe feature residential neighborhoods and public housing, making it a popular area for families due to its many waterfront parks.
Within the ward, there are low-lying areas with some houses built during the Showa era reaching 40 to 50 years of age. This is why the option of “buying used single-family homes or public housing and renovating (renovating) them while reviewing flood prevention and insulation” is expanding in Edogawa-ku.
Single-family Homes and Public Housing in Kasai and Koiwa
This area is chosen by families due to its many waterfront parks. There is also the option to continue living in Showa-era homes and public housing through a combination of buying used properties and renovating them.
Flood Awareness in Zero Meter Elevation Zones
With many low-lying areas, it is important to prepare for flooding above and below the floor. Consider the condition of the foundation and underfloor, the location of equipment, and flood prevention measures.
Seismic Reinforcement Needs for Old Houses
For older wooden detached houses, confirming seismic resistance is important. In Edogawa-ku, the seismic assistance does not specify contractors.
Be Aware of the “Boundary” of New Seismic Standards
For used detached houses, seismic standards vary by construction period. It is important to check the construction confirmation period and structure, using June 1, 1981, and June 1, 2000, as reference points.
This article summarizes the reasons, points to consider, cost averages, the latest subsidies for 2026, and how to choose contractors from the perspective of Kakeru Koumuten, aimed at helping those considering renovating used properties and vacant houses in Edogawa-ku “avoid failures”.
The Most Important Thing is “Comparative Estimates”
To avoid failures in renovations, the most crucial step is comparative estimates. First, obtain estimates from at least three companies that operate in Edogawa-ku. 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 renovating used properties. There is a growing interest in living in renovated or remodeled used houses. Here, we explain the typical reasons for renovating vacant houses and used properties.
Reason 1 To Live Comfortably as Your Own Home
A typical 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 interior, you can create a comfortable living environment. Additionally, with changes to the layout and refreshing the interior, depending on the condition of the property and the scope of work, you can achieve a home that suits your family’s lifestyle while keeping costs lower than new construction.
Reason 2 To Increase Asset Value for Sale
There are cases where a used property is purchased and renovated for the purpose of resale. The evaluation of used houses varies based on the condition of the building and location, but appropriate renovations can enhance both appearance and performance, potentially increasing the property’s appeal.
Reason 3 To Utilize as an Investment or Business
When purchasing a used property for investment or business purposes, renovations may be necessary. By transforming it into a stylish rental or share house, you can differentiate it from other properties, and depending on the location and planning, you can also expect an increase in profitability. There may be cases where initial costs are lower than new construction, and depending on the use and conditions, it may qualify for subsidies and tax incentives.
03Points to Consider When Renovating Vacant or Used Properties
Point 1 Choose a Reliable Construction Company
First and foremost, it is essential to select a contractor you can trust to handle the renovations. Used properties often have hidden areas behind finishing materials, and the internal structure and condition may not be clear until investigated or dismantled. Choose a contractor who can work according to your wishes, the structure of your home, 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 confirm which parts are deteriorating and to what extent beforehand. Since the property has been occupied by someone else, the internal damage is often not apparent without investigation. Conduct a current condition survey before starting work to understand any 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 on June 1, 1981, and homes that received building confirmation before that date adhere to the old standards. Furthermore, for wooden houses, regulations regarding joints and foundations were clarified on June 1, 2000. Before starting work, check the construction date and the condition of the building, and verify the earthquake resistance and insulation performance.
Point 4 Check Subsidy Programs and Renovation Tax Deductions
To reduce construction costs, it is important to check for subsidies and renovation tax deductions. Subsidies are provided by the national and local governments, supporting part of the costs for seismic retrofitting, energy-saving construction, and barrier-free renovations. Tax deductions include the “housing loan tax deduction” when using a housing loan, and there are systems that allow for deductions on certain costs even with personal funds. These can sometimes be used in combination, so checking in advance and planning strategically is key to a successful renovation (for the latest information, see this subsidy section).
04Cost Estimates for Renovating Vacant or Used Properties
The renovation costs for used properties and vacant houses can vary significantly depending on the degree of damage and the scope of work. First, please understand the approximate market prices by category as a guideline for your financial planning (the table below provides general estimates for typical single-family homes.

05[Latest 2026] Subsidies and Grants Available in Edogawa Ward
One way to carry out renovations on used properties and vacant houses cost-effectively is by utilizing subsidy and grant systems. As of 2026, we have summarized the main systems available for residents of Edogawa-ku.
*The following information is as of August 31, 2026. The content, duration, and budget of the systems change annually, and many will end once the budget limit is reached. Please check with our company or the respective offices for the latest information before applying. Kakeru Koumuten can assist with confirming the systems and providing necessary documents, but the application methods and applicants may vary by system.
National System: Housing Energy Saving 2026 Campaign
The government is implementing several subsidy projects targeting energy-saving renovations under the Housing Energy Saving 2026 Campaign. If conditions are met, insulation, windows, and water heater renovations may be combined for use.
This is a successor system to the “Child-Rearing Green Housing Support Project.” At least one room with an opening facing the outer skin must undergo specified “required construction,” and eco-friendly housing equipment, child-rearing compatible renovations, disaster prevention improvements, and barrier-free renovations that meet the conditions are also eligible.
Estimated subsidy limit: For buildings constructed before 1991, up to 1 million yen per unit (50,000 yen depending on construction content); for buildings constructed between 1992 and 2016, up to 800,000 yen per unit (400,000 yen for the same). Targeted construction that started on or after November 28, 2025, is eligible, and applications are being accepted from 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.
Renovations for window insulation, including interior window installation, exterior window replacement, and glass replacement, are eligible. The subsidy amount is substantial and effective for countering cold, heat, and condensation. It can easily enhance the insulation performance of used homes.
The subsidy amount varies based on the window construction method, performance, size, and the way the house is built. 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 is for the replacement of high-efficiency water heaters such as eco-cute, hybrid water heaters, and EneFarm. It is a system that works well with used properties that are planning to replace their water heaters.
Estimated subsidy amounts: Eco-cute 70,000 to 100,000 yen/unit, hybrid water heater 100,000 to 120,000 yen/unit, EneFarm 170,000 yen/unit. Eligible construction work must start on or after November 28, 2025, and applications will be accepted starting March 31, 2026 (may end early if the budget limit is reached).
Tokyo Metropolitan Government Program
High insulation windows (installation of inner windows, replacement of outer windows, glass replacement), high insulation doors, insulation materials, and high insulation bathtubs are eligible. This program offers a substantial subsidy amount that can significantly improve the insulation performance of used homes.
High insulation windows and doors have a maximum subsidy of 2,000,000 yen/unit based on the total subsidy unit price by performance and size (if including eligible security windows, the maximum is 3,000,000 yen/unit), insulation materials are 1/3 of eligible expenses, up to 1,000,000 yen, and high insulation bathtubs are 95,000 yen/unit. Pre-application starts on May 29, 2026, and application for grants and performance reports will be accepted from June 30, 2026. In principle, contracts and construction must be done after the pre-application acceptance. For details, please visit the official page.
This program provides a direct discount equivalent to points when purchasing energy-efficient air conditioners, refrigerators, water heaters, and LED lighting at registered retailers.
Typical replacement estimates: Air conditioners 9,000 to 23,000 yen, refrigerators 14,000 to 26,000 yen, water heaters 12,000 yen, LED lighting fixtures 4,000 yen (if there are replacement work costs, 6,000 yen). The amounts may vary for replacements from long-term use appliances. The eligible period is until March 31, 2027 (may end early depending on budget conditions). For details, please visit the official page.
This program supports the new installation of solar power generation systems and storage batteries in residential homes within the city. The subsidy requirements and application procedures differ for each type of equipment.
For solar power systems in existing homes, the subsidy is 150,000 yen/kW (up to 450,000 yen) for systems below 3.75 kW, and 120,000 yen/kW for systems exceeding 3.75 kW (under 50 kW). The battery package is 100,000 yen/kWh, and if you do not participate in the DR demonstration, the maximum is 1,200,000 yen per household. In all cases, the eligible expenses for subsidies are capped. For more details, visit the official solar page and the official battery page.
Edogawa Ward System
In addition to old earthquake-resistant homes, newly constructed wooden houses built between June 1, 1981, and May 31, 2000, are also eligible if they meet certain conditions. Edogawa Ward does not designate contractors, so you can also use contractors from outside the ward.
Houses designed using the ward’s earthquake retrofitting design subsidy are eligible. If you contract or start construction before receiving the subsidy decision notification, you will be ineligible. The application deadline for the earthquake retrofitting work subsidy for the 8th year of Reiwa is December 25, 2023, and the performance report deadline is February 26, 2024. For more details, visit the official Edogawa Ward page.
This subsidy is for the demolition and removal of old wooden houses and vacant houses that do not meet earthquake resistance standards. It is aimed at those considering rebuilding or utilizing the land.
Eligible expenses are 1/2 of the costs, up to 500,000 yen. From the 8th year of Reiwa, the cap has been expanded to 1,000,000 yen for some eligible areas and vacant houses. Eligible properties include old wooden houses built before May 31, 1981. For more details, visit the official Edogawa Ward page.
This is for individuals who have been certified as requiring nursing care or support. There are limits and eligibility requirements for various types of construction, such as converting toilets to Western-style, replacing bathtubs, installing barrier-free modifications, and stair lifts.
Home modifications under the long-term care insurance (maximum amount of 200,000 yen) will be prioritized. The upper limit for the subsidy amount is 2,000,000 yen, but the actual subsidy amount varies depending on the type of work, subsidy ratio, and limit per type of work. It is necessary to consult with a care manager before the work begins. For details, please visit the official page of Edogawa Ward.
Support for the removal of dangerous block walls facing the road. Can be utilized along with exterior renovations of used houses.
For individuals, the subsidy is 2/3 of the eligible costs or 25,000 yen per meter (whichever is lower), with a maximum of 2,000,000 yen. Walls over 1.2m high from the road are eligible. Contracts or construction started before the district’s approval notification, as well as removals associated with land leveling or building demolition for sale purposes, are not eligible. For details, please visit the official page of Edogawa Ward.
* Edogawa Ward does not have a uniform subsidy for exterior wall painting of general residences. Please check the national “Housing Energy Efficiency 2026 Campaign” and the Tokyo Metropolitan Government’s programs for insulation and windows. The ward also has a “Housing Renovation Financial Assistance Program” (up to 80% of the construction estimate amount, maximum 5,000,000 yen). Earthquake resistance renovations do not have designated contractors by the ward.

We performed a roof overlay construction by installing a lightweight metal roofing material “Super Galtect” over the existing slate roof without removing it. This method minimizes the area that needs to be removed compared to a complete roof replacement, making it a more efficient solution.
07How to Choose a Renovation Contractor for Used Properties and Vacant Houses in Edogawa-ku
There are many renovation companies that serve Edogawa-ku, and it can be confusing to decide which one to choose. When requesting renovations, be sure to check the following five points.
- Having extensive experience in renovation work
- Confirming the presence of warranties and aftercare services
- Obtaining estimates from multiple contractors (at least 3 companies)
- Checking if the exterior work is carried out by the company itself
- Confirming if color simulations and perspective drawings are available
1. Having extensive experience in renovation work
Many renovation contractors publish their construction achievements on their websites. If a contractor provides detailed explanations of the process with photos, it helps you visualize the outcome after the request, giving you peace of mind. If you’re uncertain, choose a contractor with ample experience.
Google and review sites can also be helpful. It is important to check the content of low ratings, the company’s responses, and the timing of posts. In particular, Google reviews are useful, but do not make your decision based solely on reviews; consider construction achievements, estimates, and warranty details comprehensively.
2. Confirming the presence of warranties and aftercare services
When choosing a contractor, be sure to check for warranties. Even within the warranty period, the response may vary depending on the type of work, materials, defects, and disclaimers. Confirm the existence of a warranty certificate, its coverage, duration, and the details of aftercare services before signing a contract.
Kakeru Koumuten Co., Ltd. offers warranties for exterior wall painting and joint sealing work. The coverage and warranty period vary depending on the work and materials. We also provide aftercare services and send out annual reminder DM for annual inspections.

3. Obtaining estimates from multiple contractors (at least 3 companies)
When requesting renovations, be sure to obtain estimates from multiple contractors. Even for the same construction content, warranties, aftercare services, and prices can vary significantly. Having multiple estimates makes price negotiations easier.
When comparing estimates, it’s important to look closely at not only the cost but also the “items in the estimate,” “confirmation of undercoating materials, sealing materials, and auxiliary paint,” and “confirmation of the process.” Lowering the rank of auxiliary components or skipping steps can reduce costs, so it’s essential to not make decisions based solely on price.
Learn more about the points to compare in competitive estimates
4. Confirm whether the company performs the exterior work in-house
Kakeru Koumuten Co., Ltd. conducts detailed hearings and investigations regarding the existing “condition,” “location,” “base materials,” “desired durability,” and “design” to propose suitable plans. While there is nothing inherently wrong with a system where partner companies perform the work, it is important to confirm whether the contracted company understands the scope of work and clearly defines the responsibilities for quality control and guarantees. If the work is done in-house, it is easier to coordinate with the site, making it quicker to respond in case of any issues.
5. Check if they offer color simulations and perspective drawings
Choosing colors and envisioning the look after construction can be challenging for both exterior and interior projects. Having simulations can reduce the risk of mistakes like “it turned out differently than I imagined.” Since it is difficult to redo once the work is done, it is advisable to choose a company that can provide flexible simulations.
08Reasons why Kakeru Koumuten is chosen for remodeling used houses in Edogawa-ku
One reason is that “Kakeru Koumuten also serves Edogawa-ku,” but
there are also “initiatives in remodeling vacant and used properties that cannot be imitated by other companies,”
which have received high praise from many customers.
We have absolute confidence in “cost,” “quality,” and “plans” for remodeling in Edogawa-ku. Please compare our estimates with those of other companies.
The most important aspect of renovation is comparing estimates. Be sure to request estimates from at least 3 companies that operate in Edogawa-ku!

09Renovation of Used Properties and Vacant Houses in Edogawa-ku | Frequently Asked Questions
We will answer the most frequently asked questions from those considering renovations of used properties and vacant houses in Edogawa-ku.
Is it better to renovate after buying a used property or consult before buying?
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 check the condition of the property you are considering in advance and providing an estimate for necessary renovations, you can establish a feasible financial plan.
What renovations should be prioritized for a used detached house in Edogawa-ku?
It depends on the condition of the building, but we prioritize areas that, if left unattended, can lead to further damage, such as leaks, termites, and structural or seismic issues. After that, we will determine the priority of exterior renovations such as the roof and walls, water areas (kitchen, bathroom, toilet), and insulation based on your budget and impact on daily life. Since the deterioration situation cannot be judged solely by the age of the building, we recommend starting with a comprehensive inspection of the entire building, including the roof, walls, foundation, underfloor, and water areas.
I hear that Edogawa-ku has many low-lying areas. Are there any points to be careful about with used detached houses?
A Edogawa-ku, there are many low-lying areas with low elevation, so renovations focused on flood prevention measures are reassuring. Let’s consider checking the condition of the crawl space and foundation, the location of the water heater and distribution board, and the installation of flood barriers. Additionally, for older wooden houses, it’s important to review earthquake resistance and insulation. The earthquake renovation subsidy in Edogawa-ku clearly states that “the ward does not designate contractors“, making it convenient for companies like ours from outside the ward to utilize it.
How much does a full renovation (full renovation) cost?
The cost of renovating a detached house varies greatly depending on the size of the building, the condition of deterioration, the scope of work, and the grade of equipment. Even for partial renovations, around 8 million yen can be a rough estimate, while large-scale full renovations that include interior and exterior work, water areas, insulation, and earthquake resistance can exceed 15 million to 30 million yen. The amount is just a general guideline, so we will first check the condition through an on-site survey and propose a prioritized plan that fits your budget.
Do I apply for subsidies myself? Is the process difficult?
Depending on the system, the applicant may vary. For example, the national “Mirai Eco Housing 2026 Project” has a system where registered contractors (construction companies) apply. For earthquake renovations or home modifications under nursing care insurance in your city or ward, the application is generally made by the individual, but we will guide you through the necessary documents and process. We will organize and inform you about “which systems can be used,” so please feel free to consult with us first.
What risks are there if I leave a vacant house as it is?
Risks include the progression of leaks and termite damage, a decrease in asset value due to deterioration of exterior walls and roofs, and the 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 special exemption for residential land from fixed asset tax may be revoked. Early inspections and necessary work according to your policy of living in, renting, selling, or utilizing the property can ultimately help reduce costs.
I am worried about earthquake resistance. How can I assess the earthquake resistance of a used detached house?
The construction period is a significant guideline. Check whether it is after June 1981 (new earthquake resistance standards) and further after June 2000 (strengthening regulations for joints and foundations). For wooden detached houses built before that, we recommend an earthquake diagnosis. There are also subsidies for earthquake renovation for wooden houses in your city or ward, which can significantly reduce costs if you qualify (for details, see the subsidy section above). Kakeru Koumuten Co., Ltd. will assist you from diagnosis to renovation.
Will I need temporary housing during construction? How long will it take?
It depends on the scope of the work. Exterior renovations and partial interior work can often be done while you are living in the house, but for large-scale full renovations that include water areas, we may recommend temporary housing. The estimated duration is about 2 to 4 weeks for exterior work and about 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 Edogawa-ku within your service area? Will there be a travel fee?
