The Tà Âmaru () is a Japanese breed of long-crowing chicken. The crow may be sustained for some 25 seconds. It is one of four Japanese long-crowing breeds, the others being the Koeyoshi, the Kurokashiwa and the Tà Âtenkà Â.
The TÃ Âmaru is thought to have originated in China at the time of the Tang dynasty; the kanji character , 'tou', represents that dynasty.
The Tomaru was registered as a Japanese natural monument of Niigata Prefecture in 1939.
The TÃ Âmaru has only one colour, black with a greenish sheen. The body is broad and compact with a full breast. The tail is held low, but higher than horizontally; although the sickle feathers may be long enough to touch the ground, this is not usually considered a long-tailed breed. The feet and shanks are dark slate-grey. The comb is single. The ears and face are red, sometimes with dark markings; in hens the face may be entirely black.
