A 9-year-old boy found a hand grenade in a rice field in Iizuka, Fukuoka Prefecture, on Monday at around 3:40 p.m., and then took it home. The boy's father discovered the object around two hours later and handed it in to a local police station.
Police then cordoned off the area for 50 meters while the bomb squad came to collect it.
Police said the grenade was around 10 cm long, 5 cm wide, shaped like a rugby ball and covered in mud. The boy was quoted by police as saying: "I found it next to a rice field where a friend and I were playing. I wasn't scared because I pretty sure it wouldn't blow up. For its size, it felt quite heavy."
Fukuoka has been the scene of numerous disputes between rival organized crime gangs, and there have been cases in which hand grenades were used as weapons. According to police, however, there are no yakuza gang headquarters near where the grenade was found, so there is a very slim chance of yakuza involvement.© Compiled from news reports
