Etsu Pacific Ocean Water Gin is distilled at the Asahikawa Distillery in Hokkaido. Hokkaido is the second largest of the four main islands in the archipelago, but the second least populated. It lies north of the island of Honshu, from which it is separated by the Tsugaru Strait.

It is surrounded by the Pacific Ocean to the east, the Sea of Japan to the west, and the Sea of Okhotsk to the north. In the Meiji era (1868-1912), the island received its present name: Hokkaido, meaning "the way to the North Sea".

Fresh water from the mountain spring and sea water from the Sea of Japan are added to carefully selected botanicals such as juniper berries, bitter orange peel, licorice root, angelica root and coriander to create this unique gin that captures the Japanese coastline in a bottle.
