Tadotsu, town in Nakatado district, Kagawa prefecture, Japan
Tadotsu is a small port town in Kagawa Prefecture, on the northwestern coast of Shikoku island, that developed around maritime trade. The old town center sits close to the water and is made up of former warehouses, merchant residences, and narrow streets running down toward the harbor.
Tadotsu separated from the nearby city of Marugame in the late 17th century and quickly grew into a major trading port for goods such as sugar, cotton, and salt. Specialized cargo vessels known as Kitamae-bune made regular stops here, connecting the town to the broader sea routes across the Seto Inland Sea.
The name Tadotsu is closely tied to sea trade, and walking through the old port districts still gives a sense of how merchants and sailors once shaped the place. Warehouses and old merchant houses remain standing along the waterfront, showing how commerce once defined the layout of everyday life here.
The old town is easy to explore on foot since historic buildings such as the Shiota Warehouse and the Goda Family House are close to one another. Stopping at the municipal museum before walking through the port area helps put the surroundings in context.
The writer Ryotaro Shiba once compared Tadotsu to Hyogo, one of the most important ports in Japan at the time, to underline how central this small town was to the country's maritime network. Coming from such a respected author, the comparison reflects how seriously the town was regarded beyond its modest size.
