Modern dentistry in Japan is said to have begun when Western dentists who came to Japan after the country opened up, such as the American W.C. Eastlake, started dental practices in the foreign settlement of Yokohama. With a strong awareness of this history, the Kanagawa Dental Association, under the initiative of its then-president Masuo Kato, opened the Dental Museum concurrently with the completion of the Kanagawa Prefectural Dental Health Center (Kanagawa Dental Association Building) in 1987.

The Heart Museum was established on April 15, 2005. Founded by Wada Precision Dental Laboratory Co., Ltd., a company that continues to create "good teeth" that allow everyone to eat energetically and comfortably every day, wishing for everyone's "oral bliss" = happiness for their mouths, it is a unique museum nationwide featuring exhibitions related to teeth and art.

The Dental Museum was opened in 1989 to promote better understanding of oral hygiene and there are few such museums in Japan. Visitors can enjoy rare experiences including seeing an ancient examination room and checking their knowledge of oral hygiene.
