In December, officers retrieved 18 hand guns, including Smith & Wesson revolvers and Colt automatic pistols, a military rifle and 670 rounds of ammunition from inside a home in an unidentified location in the prefecture.
That same month, officers received a tip indicating that an organized crime group was concealing weapons inside the residence. A search was then conducted for violations related the Swords and Firearms Control Law. No arrests were announced.
The location of the home was not announced due to the potential impact such information may have on the investigation, police said.
In June of 2007, prefectural police seized 31 pistols and 500 rounds of ammunition from a home in Yokohama.
