TOKYO/KYOTO -- Riho Matsumaru's revelation came in March. While studying in London, the 21-year-old joined a student protest against the climate crisis, one of hundreds of events held simultaneously across the globe. The message of the protests resonated with her, and spurred her to try to drive action back home.
"There is a growing sense of crisis in me," she said. "I feel anxious and frustrated about our current society. ... I want Japan to be as active as the rest of the world."
