Only have 7 days? Takamatsu and Naoshima for two days, one night in the Iya Valley, a day in Kochi, then Dogo Onsen and the Shimanami Kaido.
Times are typical. Trains and buses in Shikoku are infrequent, and a rental car opens up Iya, Cape Ashizuri and the rivers.
Shikoku's 88 temples form a loop of about 1,200 km, traditionally linked to the monk Kukai. Walking all of it takes 40 to 50 days; most people now go by car or bus, or walk it in sections over several years. Pilgrims in white are called o-henro-san, and people along the route still offer them food or a place to rest, a custom called settai.

The Wild Coast: Cape Ashizuri is sheer granite cliffs and a white lighthouse above open ocean, with a pilgrimage temple at the edge. The Niyodo River has repeatedly topped Japan's national water-quality rankings — the water reads a blue so saturated it doesn't look real from above.
Kochi Castle & Katsuo: One of twelve castles in Japan with its original keep, and the only one whose main-bailey palace also survives. Hirome Market serves katsuo tataki — bonito seared over rice straw — at communal tables, daily. Go at lunch and you eat alongside people who drove two hours for it.

Matsuyama & Dogo: Matsuyama Castle sits on a 132-metre hill — one of Japan's twelve original castles, its keep rebuilt in 1854. About 15–20 minutes away by tram is Dogo Onsen, one of Japan's oldest hot springs. The 1894 bathhouse still takes guests, fully reopened in 2024 after a five-year restoration.
Shimanami Kaido: 70 kilometres across six Seto Inland Sea islands via seven bridges, ending at Onomichi in Hiroshima. Rental terminals line the route, and you can drop your bike at a different one. The full crossing takes six to eight hours — one of the great cycling routes in Asia.

Naoshima: Benesse has spent over three decades turning a copper-smelter and fishing island into a permanent art destination. The Chichu Art Museum is buried underground, lit by natural light only, with permanent works by Monet, James Turrell, and Walter De Maria — timed tickets must be booked ahead.
Sanuki Udon & Kotohiragu: Kagawa is called Udon Prefecture — some shops open soon after dawn, and the best have lines before the door unlocks. Kotohira-gu demands 785 stone steps to the main hall. Ritsurin Garden in Takamatsu takes two hours to walk and earns them.
