TOKYO X

Developed in Tokyo and raised in small numbers, TOKYO X is known for fine-grained meat and delicately sweet fat.

TOKYO X is a Japanese brand pork (meigara-buta) from Hachioji City, Tokyo, managed by TOKYO X Producers Association. Breed / crossbreeding: TOKYO X — purebred strain (synthetic line derived from Beijing Black, Berkshire, and Duroc).

TOKYO X is a purebred strain developed by the Tokyo Metropolitan Livestock Experiment Station. Breeding work began in 1990 and took seven years. The station combined three breeds, Beijing Black, Berkshire, and Duroc, to bring together the strengths of each. In 1997 the Japan Swine Registration Association (now the Japan Pork Producers Association) registered TOKYO X as a new strain. Today the TOKYO X Producers Association manages the brand. Farms raise it in Tokyo and also in Miyagi, Ibaraki, Gunma, and Yamanashi prefectures.

Its greatest distinguishing feature is the finely grained, silky meat quality and a premium fat that releases a sweet, nut-like fragrance when heated. The lean and fat are beautifully integrated, with a clean, refreshing aftertaste that leaves no lingering heaviness. It contains approximately four times the Vitamin B1 of standard pork, making it nutritionally exceptional as well.

The feed consists of non-GMO, post-harvest-free corn and soybean meal as the primary ingredients, with a dedicated compound feed given for more than three months before shipment to enhance fat quality. The pigs are raised over approximately 210 days in a spacious, stress-reduced environment under four core principles — Safety, Biotics, Animal Welfare, and Quality — and the annual shipment of 8,000 head makes it a rarity. Individual ear-tag management and DNA-based origin verification are also conducted, reflecting the producer’s uncompromising commitment to quality.

TOKYO X is at its finest in preparations that let the ingredient speak for itself: shabu-shabu, stir-fried vegetables, or char siu pork.
