The Koeyoshi breed is found in Akita, Aomori and Iwate Prefectures. Although controversial, it is generally thought that Koeyoshi derives from a cross between Shamo (Japanese Game Bantam) and Tomaru. In 1937 Koeyoshi was designated as natural monument by the Japanese Government. The breed has White hackled plumage with a black breast, yellow shanks and feet and a pea type comb.

Koeyoshi is one of the three long crowing chicken breeds in Japan. The cock has a deep, hoarse crow, which lasts for approximately 15 seconds. Adult males weigh on average 4.5 kg and females 4 kg.
