Otaru Canal is the signature of Otaru City, and is famous for sight-seeing. There are original stone warehouses on one side of the canal (which now house restaurants and such), and the other side has a stone-paved path for pedestrians. Its scenery makes visitors feel that Otaru is a harbor city. The canal was constructed in 1923, and its purpose was for big ships to dock outside warehouses for loading. After years, this canal got to be very dirty and clogged with sludge, as hard as that may be to believe looking at it now. In 1986, the was restored to its present condition. You can enjoy walking along it both in summer and winter.
