Shiratake

Shiratake is the flagship brand of Kawachi Shuzo (now Shiratake Shuzo), the only sake brewery on Tsushima, named after the sacred Mount Shiratake on Tsushima, designated as a National Natural Monument.
It uses subterranean water drawn from approximately 10 meters underground in Keimei no Mori (Keimei Forest), selected as one of Japan's Top 100 Water Source Forests. This soft water is spring water from Mount Shiratake, promoting gentle fermentation and producing sake with a mild, sweet flavor.
Beloved by Tsushima islanders, this sake fuses Tsushima's natural blessings with traditional brewing techniques. It is cherished as a local sake unique to Tsushima, rarely found outside the island.
