It is found in northeastern China , Japan (Honshu, Kyushu, Shikoku), Korea, and Russia (Amur Oblast, Khabarovsk Krai, Primorsky Krai).[4]

It is a small snake, growing to a maximum total length of 44 cm (17 1⁄4 in), with a tail 10 cm (3 7⁄8 in) long.
Dorsally it is olive or reddish brown, with small blackish spots. Some specimens may have a dark olive or blackish vertebral stripe. The upper labials are yellow, with black sutures. On each side of the nape of the neck there is a yellow dark-edged diagonal streak, these two streaks converging posteriorly. Ventrally it is yellow, with a series of brown dots or short lines at the outer ends of the ventral scales.
Dorsal scales strongly keeled (except outer row), arranged in 19 rows at midbody. Ventrals 127–151; anal plate divided; subcaudals divided 59–79.[5]
