World K's Beijirou
Period full-body portrait.

World K's Beijirou (FB2289) holds a place in Wagyu history as one of the very first fullblood Wagyu calves born in the United States: he and his sister Fujiko were born on 24 June 1994 out of the foundation cow Okutani, sired by World K's Haruki 2. He is US-born from imported parents, not a Japan export, and his registration number (FB2289) sits in the same early sequence as the Takeda live-import bulls, which is exactly why he is easy to mistake for an imported foundation sire. Genetically he follows his sire Haruki 2's balanced, non-pure-Tajima makeup, blending Tajima with Fujiyoshi, Itozakura and Kedaka, giving him a growth-and-maternal profile rather than the extreme marbling of the Michifuku-line 2nd-gen bulls. He is a full brother to Genjiro. Beijirou is worth including for historical completeness as a landmark first-generation American-born sire, clearly flagged as US-born rather than exported from Japan. He is out of Haruki 2 and the cow Okutani; World K fed 2,000 finished steers to a 65% 9+ Australian-scale grading rate (540-day ADG 1.05kg), a good combination of Yasumi Doi and Shigeshigenami for marbling with Itozakura/Kedaka on the female side for carcass weight and growth. Sold at $30/straw.
