Founded in 1733 (Kyoho 18), Taketsuru Brewery is located in Takehara City, Hiroshima Prefecture. Takehara flourished during the Edo period as a suitable location for producing high-quality salt, and the spirit of craftsmanship cultivated by Takehara merchants in that environment became the driving force that raised Hiroshima Prefecture's sake brewing, which had lagged behind, to a national level during the Meiji era. Taketsuru Brewery, whose predecessor was also a salt manufacturer, inherited that spirit, becoming the first in Hiroshima Prefecture to use the authentic Nada-style kimoto brewing method in 2004, reviving the traditional wooden barrel brewing method in 2009, and by 2016 all of its products were pure rice sake, the original form of Japanese sake. With a rich umami flavor and crisp finish rooted in the climate and soil of Takehara, its theme is not to "not interfere with" food, but to "enhance" it. "Ozasaya" is the family name from the Edo period.
