Our History

Our founder, Hisaka Tanaka, was mobilized by schoolmen to work in an iron processing plant during World War II.

Just as the war had passed and peace had been restored, tragedy struck. Hisaka lost his father in 1945 and his mother in 1948 to illness.

Hisaka was 18 years old at the time, and he wanted to send his younger brother Umewaka (the current manager) to college. Through a relative's introduction, he worked at the Kawanishi Kitchen Store in Doguya-suji. Still, he held one thought in his heart.

The Desire to Use Ironworking Skills to Make Knives.

He visited Sakai to learn how to make knives from a master craftsman.

It was there that Hisaka learned about craftsmanship, which was unbelievable even at that time.

He lowers the hammer in front of the 1,100-degree flame to discern the slightest difference in color and temper it to sharpen with great attention to detail. Hisaka learned to make knives with skill and soul, and his desire to spread this to the world grows stronger every day.

1953. With the permission of his business mentor Tsurukichi Kawanishi, Hisaka Tanaka opened his long-sought kitchen knife shop in Doguya-suji.

Our shop is one of the few places where chefs from all over Japan can come and pick up over 2,000 different kinds of knives in response to various requests. The craftsmanship and passion of Hisaka Tanaka, our founder, is still alive and well today.

President's Greeting

Since my grandfather, Hisaka Tanaka, was engaged in knife making in Sakai and founded the company to bring knives to more people, I have the same desire.

Japanese kitchen knives are tools that can accompany you through your life or even into the next generation. It's not unusual to receive a 40-year-old kitchen knife with a sharpening service ticket, saying, "This is the knife my grandfather used."

We are proud to have supported many users over the years and created Japanese food culture in Doguyasuji. This iconic shopping street is where professional chefs come to set up their restaurants. We're thrilled you'll be able to pick up one of our kitchen knives and draw a new page in culinary culture in your country.
