The Japanese government in a belated statement protested against North Korea's firing of missiles into the East Sea on Monday.
The North fired two missiles into the East Sea at 6:20 a.m. and 6:30 a.m. They flew about 500 km and fell into an area within Japan's air defense identification zone. But the Japanese government only protested at 11:35 p.m.
Earlier on Feb. 27, the North fired four missiles but Tokyo did not protest, saying there was "no impact" on Japan's security.
The Japanese media speculated that Tokyo is keeping quiet for fear of hampering fresh dialogue with the North. Japanese and North Korean Red Cross officials met in China the same day to discuss the return of Japanese people's remains from the North.
