日本土鈴館, Museum in Gujō, Gifu Prefecture, Japan

The Nihon Dorei-kan was a private museum in Gujo, Gifu Prefecture, displaying clay bells and folk toys. Its rooms were divided by theme: Nukumori-dori showed kokeshi, ema and karakuri dolls; Kappa Renpo Kyowakoku held 800 kappa figurines; Yasuraga-kan centred on hina and Tenjin clay dolls; the Asia Mingei-kan displayed masks and toys from across Asia.

The museum opened on 1 October 1986 in Gujō, Gifu Prefecture, founded around the collection of its director, Kazuo Tōyama, who gathered folk toys, clay dolls and clay bells for more than 50 years. In August 2010 Guinness World Records certified his 16,040 clay bells as the largest such collection. It closed on 25 December 2021 because of the director's advanced age.

The museum's rooms were themed: the Nukumori-dori displayed kokeshi, ema and karakuri puppets, while the Kappa Republic held 800 kappa figurines gathered from across Japan. The Yasuraggi-kan centred on hina and Tenjin clay dolls, and the Asia Mingei-kan showed masks and toys from other Asian countries.

The museum closed permanently on 25 December 2021, so it can no longer be visited. Its former site was in Gujō, Gifu Prefecture, a 15-minute walk from Ōshima Station on the Nagaragawa Railway, or immediately at the Ōshima-naka bus stop on the Gifu Bus Hachiman-Shiratori line.

In August 2010, the museum's collection of 16,040 clay bells, assembled by director Kazuo Tōyama over more than 50 years, was certified by Guinness World Records. About 3,000 of the bells date from the early Shōwa period. The museum closed on 25 December 2021 because of the director's advanced age.
