The Japanese gecko is a small, nocturnal lizard commonly seen on house walls across Honshu, Shikoku, Kyushu, eastern China, and the Korean Peninsula. Despite its species name "japonicus," it is now considered likely to have been introduced from the Asian mainland rather than being truly native to Japan. It preys on insects and other arthropods and is notable for a rare ability to perceive color even in very dim light; it is assessed as Least Concern.
