GOTOKEN Sekkatei is a long-established French restaurant loved by not only local Hakodate citizens but also tourists. The restaurant keeps the traditional recipes from its start in 1879, which use plenty of ingredients matched to the climate of Hakodate. The main building of GOTOKEN Sekkatei was designated as a 1935 building, a country-registered tangible cultural property. It is a building that conveys the old Japanese architecture of Japan.
