This tower is near the "Kajika-so" Hotel in the Ginzandaira area. During World War2, many Koreans and Chinese were abducted and forced to work at the Ashio copper mines. About 250 people were taken to the Ashio copper mines. 109 of them died in the mines. It is said that many people died because of malnutrition.
The tower was built on 30th July in 1973 to comfort their spirits and pledge never to wage war after China and Japan issued a joint statement on the recovery of diplomatic relations in 1972.
