Around the world, young people are leading the fight against climate change. But in Japan, a conservative culture of restraint and the stigmatization of public demonstrations are making it difficult for the movement to take hold.

During the global climate strike in September, 7.6 million people gathered across 185 countries in what organizers called one of the largest coordinated protests in history.

About 5,000 people in Japan took part, more than half of whom marched in Tokyo. In comparison, more than 1.5 million people took to the streets in Italy, 1.4 million in Germany, 800,000 in Canada and more than 500,000 in the United States, according to local reports.
