This extraordinary soy sauce is made exclusively for the Ohsawa Japan Company. Uncompromising when it comes to quality, Ohsawa's brew master uses the finest ingredients: special washed Oshima Island "umi no sei" sea salt, "yuuki" soybeans and wheat ecologically grown by farmers with a deep commitment to sustainable agriculture. Each step of the traditional process is carefully performed by hand. In honor of George Ohsawa, we are using his Japanese family name, "Sakurazawa" as the brand-name of this exceptional soy sauce. Aged 24 months.
