A small, drab, sparrow-like bird (Prunella rubida) native to Japan. Often found in thickets and undergrowth.
The Japanese accentor is a species endemic to Japan, inhabiting thickets in mountainous areas.
Alternate kanji spelling; rarely used.
The name likely derives from 茅 (kaya, 'thatch grass') and 潜り (kuguri, 'diving/hiding'), referring to the bird's habit of skulking in grassy undergrowth.
