var. Japaonica is a colour variation of Euprepiophis conspicillatus once given the  subspecies status of Elaphe conspicillata japonica. This colour variation is bright red, those being bred in captivity at present are from Hokkaido Is. Japan.
There is a natural variation in pattern between animals originating from the Northern and Southern Islands of Japan. Those from Hokkaido & Kunashiri are noticeably less patterned, particularly the head region than other localities.
Captive Bred Localities: Hokkaido Is. Japan (var.Japonica), South Honshu,
Natural History:  Inhabiting the foothills and high mountains between elevations of 100 and 3000 m. They have a preference for densely planted areas such as forests. Occasionally they can be found in more open areas such as agricultural land, rice fields, highland steppes and grassy plains. On the Island of Kunashiri it is mostly found in the vicinity of water in shady moist forests. A very secretive snake and most often found under clumps of grass, leaf litter, in stone walls and rodent burrows, may also burrow down into loose soil.
