Japan’s smallest main island: four prefectures of pilgrimage temples, Iya Valley vine bridges and the Setouchi art islands.

Shikoku is Japan’s smallest main island, separated from Honshu by the Inland Sea and from Kyushu by the Bungo Channel. Four prefectures wrap a mountainous interior, the famous 88-temple Kobo Daishi pilgrimage circles the entire coast, and the Setouchi art islands sit just offshore. Foreign visitors are rare here, even though three world-class draws (Iya Valley, Matsuyama / Dogo Onsen, Kochi’s Pacific coastline) sit within a one-week loop of each other.

FAQ

How many days for Shikoku?

3 days minimum for Takamatsu + Naoshima/Teshima + a day in Iya Valley. A week unlocks all four prefectures (Takamatsu → Iya Valley → Matsuyama → Kochi). Pilgrims walking the 88 temples need 30-60 days; bus tours condense to 10.

Can I do Shikoku without a car?

Yes for Takamatsu, Matsuyama, Kochi (all on the JR network) and the art islands (ferries). For Iya Valley, the Oboke gorge is reachable by JR + tour bus, but the deeper kazura-bashi vine bridges essentially need a rental car or a local guided tour.

Best base in Shikoku?

Takamatsu for art-island day trips and Sanuki udon. Matsuyama for Dogo Onsen and a real working castle. Most international visitors who try Shikoku do a 3-night Takamatsu base; serious island-trippers add a Matsuyama leg.

Is Shikoku worth visiting if I only have 2 weeks for Japan?

If you’re focused on Tokyo/Kyoto/Hiroshima, Shikoku adds 3-4 days and is best as a Naoshima art-island extension. If you want lesser-visited Japan and have 2 weeks, dropping Hiroshima for Shikoku gives you something most travellers miss.
