Takydromus smaragdinus

Takydromus smaragdinus (Takydromus smaragdinus) is the Green Grass Lizard, a lacertid whose name reflects the green colour and elongated grass-lizard form used in field recognition. Identification should combine documented pattern, scalation, body form and locality because related Japanese reptiles may be very similar. Claims here are limited to the opened species accounts (Wikipedia, general species account; Reptile Database). Field identification should therefore remain cautious wherever photographs or diagnostic measurements are unavailable.

The species account confirms its placement in Lacertidae; ecological and Japanese locality details are not expanded here because the opened source did not supply enough species-specific information. Information absent from those species-level sources is omitted rather than inferred from relatives. Japanese occurrence follows the site's catalogue and the opened distribution accounts (Wikipedia, general species account; Reptile Database). This conservative treatment keeps unresolved parts of its natural history clearly visible to readers.
