We invented the "Tonkatsu Sauce" in 1948 in Kobe, Japan. Tonkatsu sauce has the perfect blend of spices in a thick sweet-and-sour vinegar-based sauce and adds wonderful flavors to a very wide variety of foods and dishes. Tonkatsu sauce was named after a very popular dish in Japan, Tonkatsu, deep-fried pork cutlets. We took the famous Worcester Sauce, born in the town of Worcester, England in the 19th century, as the starting point, and created a sauce that best matches such dishes as deep-fried cutlets and pan-grilled Japanese style crepes called "Okonomiyaki".

Tonkatsu sauce has become a staple seasoning in the Japanese cuisine, a must-have item in kitchens across Japan. Also, it's becoming increasingly popular in countries around the world for its great flavor, naturally long shelf life, and healthy no-fat and low-calorie appeal. In recent years, our "Oliver Tonkatsu Sauce", the first and original Tonkatsu sauce, has been adopted by many restaurants and shops around the world. We make our "Oliver Tonkatsu Sauce" in Japan from only high quality ingredients and distribute it throughout the world.
