TOKYO — The Oshima sumo-wrestling stable in Tokyo's Ryogoku district, has suffered a series of attacks since earlier this month, with the building of the stable damaged by a truck and other objects, police said Tuesday.
The police have begun investigating the cases of harassment, though stable master Oshima believes that the attacks are not linked to matters connected with the Nihon Sumo Kyokai, the national sumo wrestling association, or his stable.
