Founded in 1673, Daiichi Brewing Company is the oldest brewery in Tochigi Prefecture which has endured many challenges over time. At the end of the 19th century the brand Kaika (開化) was born, coinciding with the westernization of Japan. In 1936, they changed the character to Kaika (開華) to express the elegance in their sake, and in 1998 they switched to only producing premium grade sake. They are both historic and innovative, incorporating newer brewing techniques, and unmistakenly loved dearly by locals, as you can find them holding outdoor festivals on brewery grounds every summer.
