The first generation owner Masazo Tachikawa opened the loach restaurant called Isesho
Isegen was originally founded by Masazo Tachikawa in 1830, when the 11th Generation of the Tokugawa Shogun was ruling the country. At that time, the restaurant was called Isesho (いせ庄)and was located in the area near Ginza. Later, the second generation owner Genshiro Tachikawa relocated the restaurant to its current location (Kanda) and re-named the restaurant “Isegen”(いせ源). The new restaurant name was derived by taking a part from Isesho and another part from the owner’s name Genshiro (源四郎).
