TOKYO (AP) — Shouting “banzai!” or “live long,” thousands of people marched in Tokyo streets to the banging of traditional drums Thursday as Japan kicked off celebrations to mark May Day.

The holiday, also known as International Workers’ Day or Labor Day, marks the struggles and achievements of workers and the labor movement. Thousands of people are expected to attend rallies and marches across the U.S., including in Chicago, Los Angeles, New York and Philadelphia.

“For our children to be able to live with hope, the rights of workers must be recognized,” said Junko Kuramochi, a member of a mothers’ group who marched in Japan’s capital.

U.S. organizers say their message this year is focused on fighting President Donald Trump’s policies targeting immigrants, federal workers and diversity initiatives.

Even in Japan, some said Trump’s policies hung over the day like a shadow. One truck in the Tokyo march featured a doll that looked like Trump.
