Iichiko is a renowned Japanese producer of shochu, a traditional Japanese spirit made from various ingredients like barley, sweet potatoes, and rice. Founded by Sanwa Shurui, Iichiko is famous for its commitment to high-quality production and innovation.

Headquartered in the Oita Prefecture of Kyushu, Japan, an area known for its clean water and natural beauty, Iichiko has become a global leader in the shochu industry. Iichiko's most notable products include its flagship barley-based shochu, iichiko Saiten, which is crafted using unique methods such as the "all Koji" fermentation technique. This involves using barley Koji, a special mold that helps break down the starches in barley into sugars, enhancing the flavor profile of the spirit.

The production also focuses on the single distillation process, preserving the delicate aromas and flavors of the barley.
