River

Shimanto River is the longest river in the Shikoku region, flowing through the western part of Kochi Prefecture and boasting a total length of 196km. The river begins at Mt. Irazu in the town of Tsuno.
Known as “Japan’s last clear stream,” the river offers beautiful natural scenery for every season of the year.

There are 47 low water crossings across the Shimanto River, designed so that they will not be washed away by the river’s currents when the water level rises.
Particularly famous among them is the “Sada Low Water Crossing (Imanari Bridge),” located the farthest downstream and boasting a total length of 291.6 meters. As it is the closest low water crossing to the city of Shimanto, it is often visited by tourists.

Highlights

  • The beautiful scenery of the no-rail low water crossings, river, and mountains is quite popular.
  • Taking in the river’s scenery from a sightseeing boat is another option.
  • There are many bicycle rental facilities, so taking a bike ride through the abundant nature is a great choice.
  • The low water crossings are also used as residential roads for locals.

    日本三大清流之一,沒有遭到人為的破壞,保持原有自然樣貌。

    也因為是很鄉下的地方,沒有大型的建設開發及工業的污染,所以保有原始純樸的景色,是一條非常乾淨漂亮的河流。
