On September 29, 2007, 110,000 people demonstrated in Okinawa to protest textbook revisions announced by Japan's Education Ministry that would delete references to the Japanese military's coercive role in so-called “group suicides” (shudan jiketsu) of civilians during the Battle of Okinawa. Speakers at the protest included Okinawan survivors of the battle who had witnessed the military rounding up civilians at “assembly points” (referred to in war propaganda as “places of shattering jewels”), and distributing hand grenades to them with orders to kill themselves to avoid capture by advancing U.S. forces. Yoshikawa Yoshikatsu, a battle survivor from Kakazu Village, recalled, “After the mayor of the village yelled “Long live the Emperor! “(Tenno Heika banzai), hand grenades exploded all around us. I could hear the screams of the dying.” A few days after the protest, author Kamata Satoshi interviewed a battle survivor at her home on Tokashiki Island, another site of what Norma Field has more accurately termed “compulsory suicide.” “Kitamura Tomi remembered hearing shouts of ‘Long live the Emperor’ as grenades exploded all around her. When she became aware again of her surroundings, her eldest daughter, sitting beside her, and her husband's younger sister were both dead.”
