A group of young people has marched in Tokyo's Shibuya Ward, calling for action against global warming.
More than 1,000 demonstrators, including university students and children, took part in Friday's rally. It comes ahead of the UN Climate Action Summit that will be held in New York next week.
The marchers carried placards with slogans such as "Take action now", and chanted "Protect the Earth."
The demonstration was part of a campaign called "Fridays for Future," launched by Swedish teen climate activist Greta Thunberg.
The 16-year-old has been skipping school every Friday to bring attention to climate change. Her movement has spread around the world.
A high school senior who took part in the march said the effects of climate change are greater on the younger generations. He said they want to create a better future for themselves.
A college junior said he wants to send out a strong message when he attends an event related to the UN summit in New York.
The campaign will be carried out in at least 150 countries from Friday through September 27. Millions of people worldwide are expected to participate.
