Setouchi.

ASIA-PACIFIC/JAPAN/34.3853° N, 133.4532° E

Salt air and diesel smoke settle over the water as ferry ramps drop along the Seto Inland Sea. Spanning hundreds of islands between Honshu and Shikoku, this calm basin runs on maritime rhythms: morning fish auctions in Onomichi, citrus orchards terracing steep granite slopes, and concrete art pavilions planted into sleepy fishing hamlets. It rewards anyone willing to swap bullet-train speed for island-hopping timetables, cold udon noodles, and quiet harbours.

What to do in Setouchi

Setouchi spans the sheltered waters between Honshu, Shikoku, and Kyushu. Life here moves along ferry routes, bridge crossings, and quiet ports where morning catches dictate lunch menus. It suits travellers who prefer regional trains over frantic itineraries, cycling along seaside causeways, and exploring contemporary art installations built into century-old fishing villages.

When to go to Setouchi

Spring and autumn bring mild days, clear skies over the Inland Sea, and pleasant cycling weather on the bridges. Summer runs hot and humid, though island sea breezes help. Winter is dry and crisp, ideal for Hiroshima oysters.

Getting around Setouchi

The Sanyo Shinkansen connects main Honshu bases quickly. Ferries run frequently from Takamatsu and Uno to Naoshima and Teshima. Renting a bicycle for the Shimanami Kaido or taking local trains along the coast is simple and reliable.
