The {{Nihongo|'''Class E10'''|E10形}} was a class of {{whyte|2-10-4|T}} steam locomotives built for the [[Japanese Government Railways]] (JGR) in 1948 and designed by [[Hideo Shima]]. They were numbered E10 1-E10 5.

Following the end of [[World War II]] the JGR was prohibited by [[Supreme Commander of the Allied Powers|GHQ]] from building new locomotives due to financial difficulties. However, an exception was granted for the E10s to replace the ageing [[JNR Class 4110]] locomotives because it was not possible to substitute existing locomotives on the steep gradients of the [[Ōu Main Line]] where they were used. 

The E10 boiler was a unique design based on the [[JNR Class D52]] with the fire grate area reduced by {{cvt|0.55|m2|ft2}}.<ref>Steam locomotives of Japan p.278-279</ref>

Five locomotives were built by [[Kisha Seizo]] in 1948. They were the last steam locomotives built for Japanese National Railways.<ref>Steam locomotives of Japan p.278</ref> The last examples were withdrawn in 1962.

==Preserved examples==
One E10, E10 2, was preserved at [[Ome Railway Park]] in [[Ōme, Tokyo]].<ref>Steam locomotives of Japan p.175</ref>
