OJS48, 2010

OJS48 (short for Ojisan48) was an all-male Japanese group produced by Akimoto Yasushi. All the members are former police officers and detectives from Osaka. After releasing its first single unsuccessfully, OJS48 was disbanded in the same year that it was formed. The members now work as security guards of the Japan-based AKB48 Groups.
