Taiyo Sake Brewery was established in 1945 when 14 breweries from Murakami City and Sekikawa Village merged. Some of these original breweries date back to the Edo period, preserving their history and traditions. The combined knowledge and experience of these breweries initially produced a sake brand called 'Koshi no Tama.' Five years later, the name was changed to 'Taiyozakari.' The name 'Taiyozakari' reflects the idea that many small streams of dedication to brewing delicious sake can merge to become a great river, flowing towards the vast ocean.
