Oriental Odd-Tooth Snake

The Oriental Odd-Tooth Snake is a small snake native to Japan, found across Honshu, Shikoku, and Kyushu. Its pale brown body is marked with dark brown crossbands, and its notably dark head gives it a distinctive, striking look. Because it is nocturnal and spends much of its time hidden, sightings in the wild are rare, earning it a reputation as a "phantom snake" among Japanese reptile enthusiasts. While generally calm in temperament, it mainly preys on other reptiles, which makes feeding more demanding and is one reason it's considered a species for experienced keepers. Adults reach a total length of about 30 to 70 cm, making them relatively compact snakes with an elusive charm that appeals to dedicated keepers.

Oriental Odd-Tooth Snake key facts

Care level
Advanced
Lifespan
8-12 years
Size
30-70cm total length
Diet
Carnivorous: small reptiles such as lizards and snakes, and frogs
Temperature & Humidity
A native temperate snake ranging from Hokkaido to Kyushu, living on the floor of low-montane forest. As an animal adapted to the Japanese climate it needs no excessive heating; aim for cool, slightly damp forest-floor conditions with seasonal variation.
Enclosure
A small snake of up to 70 cm; being terrestrial it needs floor area rather than height. Place stone- and log-style hides flush with the floor and provide substrate it can work into. It is nocturnal and hides by day, so observe it in the dimmer hours. Keep a water container available at all times.
Diet & Feeding
It specialises in small reptiles, taking lizards and small snakes as well as frogs. It is difficult to convert to mice, which is much of what makes it hard to keep. Before acquiring one, make sure you have a reliable, continuing supply of appropriate food.
Temperament
Non-venomous, but when threatened it either raises its forebody in mimicry of a venomous snake or feigns death. Nocturnal and rather highly strung, it is not a species for handling. Because it eats snakes, keep it singly.
Notes
Not listed on any CITES appendix. The IUCN assesses it as Least Concern. It appears neither on the schedule of designated dangerous animals under the Order for Enforcement of the Act on Welfare and Management of Animals nor on Japan's list of invasive alien species. It is a declining Japanese endemic and appears on the red lists of several prefectures. Collection from the wild may be restricted by local ordinances or by rules covering protected areas, so check the regulations where you live first. Its narrow diet of small reptiles makes it demanding to keep.

  5. 5Compact Size, Less Space

  6. 6Appearance Changes With Age

    Juveniles show more distinct banding and a lighter patch behind the head. The pattern and coloring gradually change as the snake matures.

  7. 7A Rare, Native Japanese Species
