Zenibako, in the southwestern part of Otaru city on the Sea of Japan coast of Hokkaido, is a coastal community adjacent to the historic port city of Otaru whose canal district, canal glass workshops, and music box culture have made it one of Hokkaido's most visited cultural destinations — the elegant Meiji-era stone warehouses converted into shops and restaurants along the Otaru Canal creating one of Japan's most atmospheric historic waterfront townscapes. Zenibako Onsen Hokkaido draws on chloride-rich coastal thermal waters from the marine geological formations of the Otaru Sea of Japan coastline, providing warming maritime baths in a coastal community whose proximity to the Otaru Canal cultural district, the traditional Otaru herring fishing heritage, and the Sea of Japan coastal scenery create an accessibly positioned spa setting for visitors to the greater Otaru historic area. The Otaru Canal historic district with its stone warehouses, glass workshops, and music box museum, the fresh Otaru sushi culture recognized as among Japan's finest, and the Otaru Aquarium coastal wildlife displays create a richly cultural and culinarily distinguished spa destination on the Hokkaido Sea of Japan coast.
