A distinctive feature of unfiltered sake is that the yeast is left intact, giving it a fresh, active aroma.

It has been pasteurized (low-temperature sterilized), so it is safe to drink.

The bottle is a cool black bottle that exudes Japanese style, with kanji characters sprinkled with glitter for a stylish look.

The temperature in Koga in winter drops to between 0 and 10 degrees.

This harsh cold suppresses yeast activity and slows fermentation.

This preserves the flavor and quality of Koga Ninja Sake.

It is produced at a brewery with 150 years of history in this area, which is blessed with soil and water that are perfect for sake brewing.
