LMR Yoshihiro 4335B is one of Lone Mountain’s younger sires by Itoshigenami TF148 from a dam by LMR Yojimbo 634S.

There are three key families in the Tajima line, the Nakadoi, Okudoi and Kumanami and the Kumanami line originated in 1957 with the birth of Shigekanenami and descended from a female of the Nakadoi line and for a Hyogo Prefecture bull of his time, Shigekanenami had exceptional weight gain and an outstanding proportioned body.

The most prolific and exceptional son of Shigeshigenami, according to Kenichi Ono, produced progeny that had the best consistency of meat quality of which he said, “the meat quality is typically extraordinary”.

Itoshigenami TF148 was sired by Shigeshigenami, the result of a sire to daughter mating and TF148 exhibits a triple cross of Shigekanenami J6109, and therefore is highly linebred in the Kumanami bloodline.

LMR Yoshihiro 4335B is a medium frame bull said to weigh 1,650 pounds with excellent conformation and he is being used extensively in the Lone Mountain fllblood breeding program to produce maternal characteristics while enhancing carcass quality.

Lone Mountain believes that Itoshigenami TF148 is one of the best Wagyu bulls available to breeders in the West and that is the prime reason they have used him to create several extraordinary herd sires like LMR Aoichi 2468Z and they LMR Yoshihiro 4335B will live up to the standards set by LMR Aoichi.

Itoshigenami TF148 is very highly rated by BREEDPLAN with an outstanding Fullblood Terminal Iindex and Marbling EBV and one of his sons, Mayura Itoshigenami Jr A0139 from a dam sired by WKS Sanjirou has an astronomical Fullblood Terminal Indez and Marbling EBV based on actual carcass data with 78 carcasses analyzed and very high accuracy.

The genetics of Mayura Itoshigenami Jr A0139 are closely held and so far the only time his semen has been sold at auction was in 2016 and brought $30,500 for only 10 straws.

A son of Mayura Itoshigenami Jr A0139 was sold for a record-breaking price of $105,000 Australian dollars, the highest amount ever paid for a Fullblood Wagyu bull outside of Japan.

Pictured here is the rib eye of another paternal brother to 4335B that is an example of TF148’s marbling ability as this steer was harvested at 30 months of age and was F11 positive like his sire.

4335B’s dam is sired by LMR Yojimbo, the sale topper in the initial 2008 LMR Production Sale 2008 where he sold for $35,000.

In the 2017 LMCC Sire Performance Study, Yojimbo was ranked third as a Sire for Marble Fineness at 30.73 based on 18 carcass images and ranked fourth for IMF at 31.18% and TF148 was ranked fifth with 30.73% average based on 25 images studied.
