Japan Heritage story
Otaru, the heart of Hokkaido: a merchant city saved by its people
北海道の『心臓』と呼ばれたまち・小樽
The writer Kobayashi Takiji called Otaru the heart of Hokkaido. Railways, a busy port and banks made it northern Japan's leading city, and when it faded, its citizens fought to save the canal and warehouses that make it one of Japan's best-loved tourist towns today.

The story
Otaru started as a herring fishing ground. Hokkaido's first railway was built to carry coal from inland mines to its port, and as settlers poured into Hokkaido, Otaru became their supply base, with stone warehouses lining the shore. After the Russo-Japanese War it was the gateway to southern Sakhalin, and up to 25 banks gathered along the Iro-nai bank street, designed by Japan's leading architects, including Tatsuno Kingo for the Bank of Japan.
When coal gave way to oil, trade collapsed and the Otaru Canal filled with mud and sunken boats. The city planned to fill it in for a road. Citizens fought back for ten years: young people held the Port Festival in Otaru, which drew 60,000 people, and gathered 97,000 signatures in two months. Part of the canal was saved as a promenade, and the movement became a model for townscape protection across Japan.
