The most important characteristic of Japanese beef is the "white parts of fat" in the meat, known as sashi in Japanese. The Sashi is interspersed between layers of red meat and gives the beef a marbled pattern.

Great care is taken to produce marbling, apart from being killed and eaten thing, cows in Japan are said to live a king's/emperor life. They are fed high quality grains, and each farmer has their own blends and secret ingredients . To keep their appetite  during hot summer months, cows are sometimes fed beer or sake. The cows are raised in stalls to help create fatty marbling, so they are taken outside for leisurely walks in the afternoon to get some sun and fresh air
