Wooden art ki-gu-mi “”Matsumoto Castle””, scheduled to be released at the end of July, was featured twice in the Shinano Mainichi Shimbun on July 5 and 11. The ki-gu-mi Matsumoto Castle, which is a faithful reproduction of the real thing, is a wooden puzzle that can be assembled without using tools while feeling the warmth of wood. We received a great response from people who subscribe to the Shinano Mainichi Shimbun as well as from people in Nagano Prefecture.
