On April 20, 2023, Asahi Shimbun introduced a comment by Professor Maiko Ichihara, GGR researcher and professor of the Graduate School of Law at Hitotsubashi University. The professor commented on the article “Hong Kong Students Studying in Japan Arrested by the Hong Kong Police for Posting on the Internet.” This article reported a Hong Kong student studying in Japan who was arrested on suspicion of violation of Hong Kong National Security Law during a temporary return to Hong Kong. The Hong Kong police explained that she was arrested because of her online postings about Hong Kong independence violating the law. Professor Ichihara explained that with the Chinese government’s increasing suppression, there are numerous cases of danger to the safety of those who are engaging in activities in other countries. The professor noted that Japan needs to take flexible approaches, including reviewing measures to support people’s freedom in Japanese society. In addition, the professor stressed the necessity to raise issues with the Japanese government about the problem regarding arrests for speech activities in Japan and violations of sovereignty.
