Takydromus tachydromoides, the Japanese grass lizard, is a wall lizard species of the genus Takydromus. It is found in Japan. Its Japanese name is 'kanahebi' (ニホンカナヘビ). 'Hebi' means 'snake' in Japanese, although this lizard is not a snake. There are three species of lizards found on the four main islands of Japan. The other two are the Japanese gekko (also known as Schlegel's Japanese gekko, Gekko japonicus,or 'yamori' (ヤモリ) in Japanese) and the Okada's Five-lined Skink (Eumeces latiscutatus, also Plestiodon latiscutatus; the five lines on its back are only visible in its juvenile form).

No species of the same family or order lives in Tokyo, so these are its closest relatives here: other reptiles.
Possible
About 30% of wildlife watchers report a Japanese Grass Lizard sighting in Tokyo on a given day, based on 734 verified sightings from GBIF citizen-science data. It is the 3rd most-seen of the 15 reptiles we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
June and September
In those months about 40% of wildlife watchers report a Japanese Grass Lizard in Tokyo on a given day, against under 5% in December to February, the lowest months. Those are among Tokyo's wettest months, with about 200 mm of rain a month against 75 mm in February.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Japanese Grass Lizard sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
3rd of 6
Of the 6 cities where we can rate Japanese Grass Lizard sightings, Tokyo ranks 3rd at about 30%. The best odds are in Nagoya (Japan, about 40%) and Sendai (Japan, about 30%).
GBIF citizen-science records
It is estimated from how often the Japanese Grass Lizard is recorded against all the reptiles logged in Tokyo (734 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
