Former Mitsui Bank Otaru Branch

The Former Mitsui Bank Otaru Branch is a Renaissance-style structure with classical proportions and carved stone details throughout its facade. Inside, a vaulted ceiling defines the main hall, creating a sense of height and formality typical of early 20th century banking architecture.

Construction was completed in 1927 under architect Sone Tatsuzō, reflecting the economic expansion of northern Japan during that era. The building represents when Otaru was a major financial hub and new banking structures symbolized regional prosperity and modernity.

Today the building serves as a contemporary art space where exhibitions connect modern works with its classical surroundings. Visitors experience how current artistic practices interact with the period details of the interior.

The building is located near Otaru's harbor district and is easily reached on foot from the town center. Visitors should take time to observe the architectural details both outside and inside, as the structure offers much to appreciate for those interested in early 20th century design.

The interior features rotating projection art displays that showcase the natural seasonal changes of Hokkaido throughout the year. This contemporary addition merges the historical structure with modern visual technology.
