Abandoned School Transformed Into Cloud Solar Power Model

Oct 08, 2025 | News On Japan

TOKYO - A first-of-its-kind cloud-based solar power plant in Japan has been established in Tokyo’s Setagaya Ward, utilizing the rooftop pool area of a closed school. An event was held to celebrate the naming of the facility, where local elementary school students were invited to choose its official name.

The plant, set up on the former rooftop pool, uses solar panels previously installed at commercial facilities in the Tokyo metropolitan area.

The electricity generated here can be subscribed to by individuals online, allowing them to contract specific sections and use the power at home for a monthly subscription fee. Ahead of the planned start of power supply in November, the winning name proposed by local students was unveiled as "Jirijiri Reuse Power Plant."

Eiji Oishi, CEO of UPDATER, said: "There are still many unused pools that can be put to good use. We hope to contribute to making this initiative from Setagaya a nationwide model."
