Tokyo-X

Tokyo-X is a Japanese breed of domestic pig, bred for high quality pork production. It is unusual for its marbled meat, rarely seen in pork. The Tokyo-X breeding effort was started in 1990 by the Tokyo Metropolitan Livestock Experiment Station, combining bloodlines from the Duroc (US), Berkshire (UK), and Beijing Black (China) breeds. Five generations of breeding and selection ended in 1997 when the breed went to market. Tokyo-X was also featured on the Japanese television program Iron Chef, where the cooks had to use it as an ingredient in each of their dishes.

Life Span 15-20 years
Weight 50-350 kg

What to Know Before Buying a Tokyo-X

Finding a responsible Tokyo-X breeder requires more than browsing classified ads or responding to social media posts. The USDA requires any breeder who sells pigs commercially — especially those selling online or through third-party dealers — to hold a federal license and submit to regular inspections. A legitimate breeder should be willing to provide their USDA license number, invite you to visit their facility, and show you where the animals are housed and socialized.

Before committing to a purchase, ask the breeder for veterinary health records, vaccination documentation, and any genetic testing results relevant to the Tokyo-X. Reputable breeders will also ask you questions in return — about your living situation, experience with animals, and ability to provide long-term care. A breeder who asks no questions and is eager to ship an animal immediately is a significant red flag.

Use the search tool below to check whether any USDA-licensed facilities breeding Tokyo-Xs appear in our database. If they do, review their inspection history carefully. Look for patterns of violations, pay attention to severity levels, and compare their compliance grade with other breeders in the same state. This due diligence takes minutes and can save you from supporting a facility with documented animal welfare problems.
