Before exploring the world of cuisine, many generations of the Tsuba family had been Tsuba-sword guard artisans in the Kaga domain. In 1752, Jinbei Tsuba III opened a small restaurant alongside his main business of sword guard making. This was the origin of Tsubajin as a Japanese restaurant (Ryotei). The restaurant gained a great reputation among the feudal lords, and soon it was recognized as the best restaurant in the Kaga domain. After the Meiji restoration in early 19th century, literary masters including Saisen-Muro and political figures including Ito Hirobumi, the first Prime Minister of Japan, had all dined at Tsubajin to enjoy specialties from the Kaga region. Today, Tsubajin welcome guests from all around the world to experience one of the most historical and traditional Japanese restaurants in not only Kanazawa, but also Japan.
