With a history of over 370 years, we are the oldest sake brewery in Aomori. Named after the majestic Mount Iwaki, our sake is crafted using its pure underground water and rice grown in the fertile Tsugaru Plain. From rice washing to koji-making, fermentation, and pressing, every step is done by hand with dedication. Committed to producing only junmai sake, we create a rich, full-bodied, and dry style—distinct even among the bold sakes of the Tsugaru region—while ensuring a smooth, enjoyable drinking experience.
