On a rainy Saturday afternoon in central Tokyo, 50 or so Chinese people packed into a gray, nondescript office that doubles as a bookstore. They came for a seminar about Qiu Jin, a Chinese feminist poet and revolutionary who was beheaded more than a century ago for conspiring to overthrow the Qing dynasty.

Like them, Ms. Qiu had lived as an immigrant in Japan. The lecture’s title, “Rebuilding China in Tokyo,” said as much about the aspirations of the people in the room as it did about Ms. Qiu’s life.

Public discussions like this one used to be common in big cities in China but have increasingly been stifled over the past decade. The Chinese public is discouraged from organizing and participating in civic activities.

In the past year, a new type of Chinese public life has emerged — outside China’s borders in places like Japan.

“With so many Chinese relocating to Japan,” said Li Jinxing, a human rights lawyer who organized the event in January, “there’s a need for a place where people can vent, share their grievances, then think about what to do next.” Mr. Li himself moved to Tokyo from Beijing last September over concerns for his safety. “People like us have a mission to drive the transformation of China,” he said.
