Founded in 1822, the brewery discovered an ideal well on its grounds with the perfect water quality and abundant supply for sake brewing. The water was named 'Kasen' after a historical saying, 'This is truly a spring to celebrate.' Even today, the brewery uses water drawn from this well. Surrounded by centuries-old zelkova trees, the brewery has always prioritized quality over quantity, adhering to the philosophy of 'crafting carefully and selling carefully.' Their long history of consecutive awards at sake competitions is a testament to this commitment.
