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).

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.

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.

Founder of Kyowa Musen Kenkyujo, present Kyowa Electronic Instrument, Osamu Watanabe (ja:渡邉理, Watanabe Osamu) produced and begun to sell first Japan made strain gauge type K-1 covered with red colored felt in 1951. Meanwhile Ministry of Transport Technology Laboratory section Ship Structure asked him to make prototype strain gauge under the circumstances that imported strain gauge, from United States and others, were widely used but high price, and also strain gauge under research stage was rail transport use. He worked for Army Ministry Aviation Laboratory during war time, recalled survey of shot down B29 strategic bomber and succeeded usable strain gauge after trial and errors. The strain gauge is 20.5mm, fine resistance wires size 25μm and 120Ω resistance covered by red felt for protection, to measure as the first stress test in the ship, then resulted that well change over to welding joint from rivet joint in strength required. Imported strain gauge from United States cost more than Yen1,000, and newly produced one is low cost only Yen86, therefore various measurement instrument uses this strain gauge especially contributed in mechanical engineering area, and it became indispensable component. – Tokyo
