The Museum of Modern Toy Music Box Yumekan was opened on September 9, 1995 at Ushiroyama, the highest peak in Okayama Prefecture. Toys from around the world that are made in hopes of the healthy growth of children. We have an antique music box that was made over 100 years ago and has impressed people. ​On April 1, 2010, we moved to Yunogo Onsen in Mimasaka. Since then, it has continued as a small museum in Yunogo Onsen. ​Near the museum is the “Showakan” with nostalgic tin toys. There is also a “Tetsudo Model Museum” with a model railroad diorama, so please enjoy it.
