Viral videos circulated online showed that more than 1,000 Japanese demonstrators gathered in Tokyo’s Shinjuku district on Saturday to mark a local peace festival. Holding placards and glowing sticks, the people at the gathering chanted “Apologize to China” and “Prime Minister Takaichi, apologize,” just a few days after a 23-year-old second lieutenant in Japan's Ground Self-Defense Force, forcibly broke into the Chinese Embassy in Tokyo while carrying an 18-cm blade and threatened to kill diplomatic personnel on March 24.
