Former Hokkaido Bank Head Office, Historic bank building in Otaru, Japan

The Former Hokkaido Bank Head Office consists of a stone main building of two storeys above ground with a partial basement, doubled in size during the Taisho era, and a 1931 reinforced-concrete annex of three storeys above ground and one below. The main building was erected in July 1912 for the former Hokkaido Bank, unrelated to today's Hokkaido Bank. Its facade has changed little, though window and door frames were converted to aluminium sashes.

Built in July 1912 as the head office of the former Hokkaido Bank, an institution unrelated to today's Hokkaido Bank. In 1944 it was absorbed into Hokkaido Takushoku Bank, and the building later served as the Hokukai Maritime Bureau. Chuo Bus acquired it on 24 August 1965 and still uses it as its head office.

Since 1996 part of the building has housed "Wine Cafe & Shop Otaru Vine". The name replaces the W of Wine with the B of Chuo Bus and of Bank, and also echoes the German word Wein. The bank entrance now faces the wine shop, while the bus company's entrance sits beside the rear annex.

The building stands about seven minutes on foot from Otaru Station, and the Chuo Bus stop "Nihon Ginko Kinyu Shiryokan (Otaru Vine-mae)" is right beside it. The main entrance now serves the wine cafe and shop Otaru Vine; the Chuo Bus head office entrance is around the back, next to the annex.

The building's name is a pun: Otaru Vine takes the W of Wine and replaces it with the B of Chuo Bus and the B of Bank, while also echoing the German word Wein. The bus company has owned the former bank since 1965 and still has its head office here. The main entrance now belongs to the wine cafe; the bus company entrance is around the side by the annex.
