The JNR Class D51 is a 2-8-2 Mikado steam locomotive designed by Hideo Shima, an engineer who would become the driving force behind the creation of the Shinkansen.

The class was built by various manufacturers, such as the Kawasaki Locomotive Works, from 1936 to 1945 as a mixed-traffic engine, and was one of the most successful and most numerous types of steam locomotives produced in Japan. (Even during World War II, they were used to deliver weapons and vehicles across Japan to supply the Japanese Imperial Army troops.)

The Class D51 inspired the design of many other types of steam locomotives, was one of the first to use a knuckle-style coupler, and eventually became an iconic steam locomotive in Japan. (Like with the American Standard in the US.)

A total of 1,115 were built, with 178 surviving into preservation; two, D51 200 and D51 498, are in operational condition.
