Koshoyu Itsutosedzukuri is a special selection Japanese soy sauce brewed and aged for five full years, delivering a bold, umami-rich flavor with an 18.55% salt content. Made in limited quantities using traditional methods, each 200ml bottle reflects the patience and care of artisanal brewing.
The ingredients are chosen with care: domestic organic whole soybeans from the Michinoku region, domestic organic wheat, and sun-dried coarse salt. Its bold, savory profile makes it ideal for dishes where soy sauce takes center stage, including soba dipping sauces, salad dressings, and rich glazes.
This slow five-year fermentation is what sets the sauce apart, building the kind of deep, complex flavor that can't be rushed. You can choose a sleek black gift box for gifting, or skip the box if it's for your own kitchen.
Keep it at room temperature, away from direct sunlight, before opening. Once opened, store it in the refrigerator below 10°C, and enjoy its peak taste within its one-and-a-half-year shelf life.
