With its harsh winters, remote location and pristine waters, Hokkaido has gained quite a reputation as a treasure trove of fresh food and ingredients. If you are talking milk, simply add the "Hokkaido" tag in front of it and it becomes super-excellent milk. Same goes with uni, potatoes, corn, rice, wagyu and many other ingredients!
Ozaki Wagyu is bred in a small farm and the beef is sold direct to restaurants. As such, Ozaki-san is not constrained to use a standardized feeding regime. Instead, he has his own special formula for maximizing beef flavour which includes seaweed and charcoal which he has developed through years of experimentation!
