Mechanical Engineering Heritage (Japan)

The Mechanical Engineering Heritage (Japan) (機械遺産, kikaiisan) is a list of sites, landmarks, machines, and documents that made significant contributions to the development of mechanical engineering in Japan. Items in the list are certified by the Japan Society of Mechanical Engineers (JSME) (日本機械学会, Nihon Kikai Gakkai).

Overview[]

The Mechanical Engineering Heritage program was inaugurated in June 2007 in connection with the 110th anniversary of the founding of the JSME. The program recognizes machines, related systems, factories, specification documents, textbooks, and other items that had a significant impact on the development of mechanical engineering. When a certified item can no longer be maintained by its current owner, the JSME acts to prevent its loss by arranging a transfer to the National Science Museum of Japan or to a local government institution.

The JSME plans to certify several items of high heritage value over years.

Categories[]

Items in the Mechanical Engineering Heritage (Japan) are classified into four categories:

1. Sites: Historical sites that contain heritage items.
2. Landmarks: Representative buildings, structures, and machinery.
3. Collections: Collections of machinery, or individual machines.
4. Documents: Machinery-related documents of historical significance.

Each item is assigned a Mechanical Engineering Heritage number.
