Tokyo enacts ordinance mandating solar power for homes, first in Japan, starting in spring of 2025

December 15, 2022
On December 15, the final day of the regular session of the Tokyo Metropolitan Assembly, a revised ordinance related to the nation’s first mandatory installation of solar panels on newly constructed single-family homes was passed and enacted with a majority of votes in favor. The aim is to reduce greenhouse gas emissions in the residential sector. The new system will begin in April 2025, after a preparatory period to support businesses and inform residents.
 According to the Tokyo Metropolitan Government, major housing manufacturers will be obligated to install panels on buildings with a total floor area of less than 2,000 square meters, including residences. Purchasers will be required to reduce the environmental impact of their homes as an obligation to make an effort.
 The TMG estimates that if 4-kilowatt panels are installed, the initial cost of 980,000 yen can be recovered in 10 years through the income from electricity sales, and only 6 years if the TMG subsidy is used.
