Mitsuboshi Honjin

Mitsuboshi Honjin is the flagship brand of Senryu Shuzo, named after the honjin residence of the Hirado domain adjacent to the brewery. The three-star mark uses the mitsuboshi (three stars) of the Matsuura clan of Hirado.
It is a nihonshu brewed with traditional techniques that stand the test of time, where the koji-making process relies not on machines but on the meticulous temperature management guided by the experience and intuition of the master brewer.
With a history of being founded by order of the Hirado domain, it is a nihonshu brewed while preserving traditional methods as a brewery deeply tied to the region's history. The moto-gura (yeast starter storehouse) still in use today is said to date from the founding during the Genroku era and is a designated tangible cultural property of Nagasaki Prefecture.
