Japan is advancing the OHISAMA project, aiming to transmit solar power from space to Earth for commercial use. The initiative involves a partnership among industry, universities, and government, targeting a key demonstration in fiscal 2025.

A satellite equipped with solar panels will collect sunlight in orbit, convert it to microwaves, and send it to a receiving station on Earth, where it will be converted back to electricity. Led by Professor Naoki Shinohara of Kyoto University, the project also involves the Japan Aerospace Exploration Agency.

Challenges include constructing a large solar array in space and ensuring safe energy transmission. The government views this technology as vital for achieving carbon neutrality by 2050.
