Where is Setouchi?
The Setouchi region is the area bordering the Seto Inland Sea, encompassing parts of Honshū, Shikoku, and Kyūshū and forming a corridor between western Japan and the Kansai region. The Inland Sea is sheltered by the surrounding mountains, resulting in a temperate climate with relatively low rainfall and mild winters, making it one of Japan’s most stable weather zones.
What is the historical significance of Setouchi?
Historically, Setouchi has served as a vital maritime route, enabling trade and cultural exchange between eastern and western Japan, as well as with the Asian continent. Kitamaebune merchant ships carried manufactured goods such as cotton, mosquito nets, and combs from western Japan through the Inland Sea, out into the Japan Sea through the Kanmon Strait and up the Japan Sea Coast all the way to Hokkaidō, bringing back commodities like fish and rice from northern Japan. Setouchi was home to pirates and maritime clans that evolved into Japan’s navy. During the feudal era, its strategic position fostered the rise of castle towns and port cities, and later, industrial development along the coast. The region played an important role in the modernization of Japan and retains a fascinating legacy distinct from that of central Japan.
What is the gastronomy of Setouchi like?
Setouchi’s cuisine reflects its maritime geography, with specialties such as fresh sea bream, anago eel, and citrus from the islands. Kagawa’s Sanuki udon and Hiroshima’s savoury okonomiyaki are notable regional dishes that reflect local traditions and ingredients. The region is also known for its excellent sake. Two cities, both named Saijō, face each other across the Inland Sea, and both are celebrated producers of Japan’s traditional beverage. It was at Saijō in Hiroshima that fragrant ginjō sake was first developed.
What adventure awaits in Setouchi?
For the adventurous traveller, Setouchi has great appeal thanks to the variety of activities to be enjoyed. The Inland Sea is perfect for fishing, kayaking, and SUP, while its islands and coasts are great for cycling and hiking, or just lazily swimming off its beautiful beaches. With its wide geographic range, the area offers many culinary adventures too.
What is there to see and do in Setouchi?
The region is also renowned for its diverse scenery—quiet island villages, coastal landscapes, and historic merchant port towns. Places like the art islands of Naoshima and Teshima, the vermilion torii of Miyajima’s Itsukushima Shrine, and the Shimanami Kaidō cycling route reflect Setouchi’s blend of natural and cultural heritage.
