The Class 8620 (8620形) is a type of 2-6-0 steam locomotive built in Japan from 1914 to 1929. It was Japan's first mass-produced passenger locomotive. A total of 672 Class 8620 locomotives were built.[1] Originally they had a symmetry of line with shapely cast iron chimneys which gave way to plainer chimneys and smoke deflectors were added in later years.

A total of 42 Class 8620 locomotives were built for Imperial Taiwan Railway from 1919 to 1928. After World War II, they were taken over by Taiwan Government Railways, and were classified CT150.[2][3]

KATO have made models in N gauge of the 8620 in the Tohoku region as well as SL Hitoyoshi in a special 4-car limited edition boxed set. Plarail have also depicted the 8620 in the form of SL Hitoyoshi and SL Aso Boy.

The Class 8620 has made appearances in notable forms of Japanese media. Maitetsu, a visual novel developed by now-disbanded visual novel developer Lose, featuring anthropomorphic depictions of steam locomotives known as "Raillords". Hachiroku, a depiction of class leader No. 8620, is the main heroine of the novel.

The Class 8620's popularity would rise when the locomotive would be featured in the movie Demon Slayer: Kimetsu no Yaiba – The Movie: Mugen Train, taking place on a train pulled by the Mugen Train, modeled after the real No. 8620 on display at the Ome Railway Park. The two operational Class 8620s, 8630 and 58654, were cosmetically modified to match the train as seen in the movie and operated with these cosmetic modifications.
