The JGR is a 0-6-0 steam locomotive formerly operated in Japan by Japanese Government Railways.
The driving wheel diameter was 1092mm and the tender has two axles. The valve gear is an Allan type with Salter safety valves on a domed boiler. It originally had a rapid ejection (pop) safety valves and the locomotive itself had no brakes, those being only on the tender.
This class was little changed compared to the 2-4-0 tank locomotive imported at the same time, aside from having brakes on the locomotive body and an improved safety valve. Some engines were given larger cylinders.
