Child-Rearing Eco Home Support Project

Last year’s Child Eco Home Support Project ended on September 28, as the amount of subsidy applications reached the budget limit, and the acceptance of grant applications and reservations has concluded.

This year, a new initiative from the Ministry of Land, Infrastructure, Transport and Tourism is the Child-Rearing Eco Home Support Project.

The Child-Rearing Eco Home Support Project provides 1 million yen in support for acquiring newly built homes with high energy-saving performance (ZEH level) that are easily affected by rising energy prices, aimed at child-rearing households and young couples.
By supporting energy-saving renovations of homes, this project aims to support energy-saving investments by child-rearing households and young couples, contributing to the realization of carbon neutrality by 2050.

Eligible Participants

Those who meet the following ①and ② are eligible.

①. Those who will enter into a construction contract with an eco home support contractor and carry out renovation work

Others

Regarding Duplication of This Subsidy

  • For one residence, if the contractor has received an increase in the subsidy limit for “renovation,” they cannot receive subsidies for “new custom-built houses” or “purchase of new condominiums” for that residence or any other residence.
  • For one residence, if the contractor has received an increase in the subsidy limit for “renovation,” they can receive subsidies for “renovation” for a different residence, but they cannot receive an increase in the subsidy limit for “renovation” again.
  • For the same residence that received a “renovation” subsidy, they cannot receive subsidies for “new custom-built houses” or “purchase of new condominiums.”

Regarding Duplication with Advanced Window Renovation 2024 Project, Hot Water Energy Saving 2024 Project, or Rental Collective Hot Water Energy Saving 2024 Project

Some of the building materials and equipment eligible for “renovation” are also eligible for subsidies under the “Advanced Window Renovation 2024 Project,” “Hot Water Energy Saving 2024 Project,” or “Rental Collective Hot Water Energy Saving 2024 Project.” Depending on the performance of the eligible materials and equipment, both projects can be used together (even under the same construction contract and timeline).
However, for renovation work that has received subsidies under this project, it is not possible to receive duplicate subsidies under the “Advanced Window Renovation 2024 Project,” “Hot Water Energy Saving 2024 Project,” or “Rental Collective Hot Water Energy Saving 2024 Project.”

Combination with Other Subsidies

For the same eligible renovation work, it is not possible to receive duplicate subsidies from other national subsidy programs. However, regarding local government subsidy programs, they can be combined unless they are funded by national expenses.

Restrictions on Disposal of Assets

Contractors who receive grants for this project cannot use, transfer, exchange, lend, provide as collateral, or demolish the equipment obtained with the grant without the approval of the government or the secretariat for 10 years after the eco-home support provider has received the grant payment. (This does not apply if selling, transferring, or lending the property as a residence.)

Storage of Accounting Documents

Eco-home support providers must clearly separate the costs incurred for the grant project from other accounting, maintain books that record the details of their income and expenditures, organize evidence documents related to this income and expenditure, and keep these books and documents for five years after the end of the fiscal year in which the grant was received.

2Regardless of the floor level, the classification in the table below is based on the building method

Single-family homes

A building with one independent dwelling unit

Multi-family housing

 

A building that houses multiple dwelling units or other uses (such as stores or warehouses) coexisting

Low-rise multi-family housing
