City Green Association will host the first City Green Cup 2027 at Shibuya Stream Hall on Wednesday, March 3, 2027. Fifty student organizations and teams from across Japan will gather for a festival-style project competition.

Student organizations and teams of three or more can take part. The selected 50 will share their work and vote for teams they want to support. The top 20 are expected to pitch on the main stage, followed by a final six and a grand prize. The selection process will be confirmed in the application guidelines.
