The Dai 7 Itozakura line, begun in 1970, is derived from Fujiyoshi cattle in Okayama Prefecture and known widely for frame size, good weight gain and gentle nature. This line is quite popular and used everywhere in Japan. Dai 7 Itozakura J65 was so famous, in fact, that his picture was placed on a Japanese telephone card.

His renowned sons and grandsons include Itomichi J1158, Kitaguni 7-8 and Itozurudoi TF151. When these bulls are crossed with highly marbling cows, the Itozakura line bulls will enhance growth. Then when the cows are mated back to a highly marbling Tajama bull, the results are larger framed animals that marble extremely well. This rotation breeding plan is known as Modashi Kohai in Japan.
