The Shikoku Mountains form a central mountain spine running roughly east-west across Shikoku island, separating the island’s northern and southern coastal plains. The range includes Shikoku’s highest summit, Mount Ishizuchi at 1,982 metres.

The ranges are the product of tectonic uplift and volcanic activity that shaped Shikoku’s interior; they historically formed natural barriers between communities on the island’s north and south coasts. Many peaks have long been associated with mountain worship and local pilgrimage routes.

The range stretches across central Shikoku, influencing parts of Ehime, Kōchi, and Tokushima prefectures and forming the island’s primary watershed.

  • Highest peak: The highest summit reaches 1,982 metres, making it the tallest peak on Shikoku and one of western Japan's more prominent mountains.

What to See #

  • Mount Ishizuchi: Mount Ishizuchi, the highest peak in the range and on Shikoku, rises to 1,982 metres and is a popular destination for hikers and religious pilgrims.
