Shiwaku Islands

The Shiwaku Islands (塩飽諸島, Shiwaku-shotō) are a group of nearly 30 small islands scattered across the tranquil waters of the Seto Inland Sea, situated between Kagawa and Okayama Prefectures. These islands boast a rich maritime legacy, having once served as the stronghold of the Shiwaku Navy, a respected seafaring force active during Japan’s Sengoku (Warring States) period. The Shiwaku sailors were renowned for their exceptional navigational skills and semi-autonomous status, entrusted with protecting vital shipping routes. Today, the islands offer a captivating blend of natural beauty, traditional culture, and historical depth, making them an ideal destination for travelers seeking an authentic taste of regional Japan away from the crowds.

Among the standout islands is Honjima, the largest and most historically significant, where visitors can stroll through well-preserved Edo-period neighborhoods and explore relics of the naval past at the Former Government Office. In contrast, Takamijima offers a more contemporary experience, known for its modern art installations that form part of the acclaimed Setouchi Triennale art festival. Outdoor enthusiasts can enjoy scenic hiking trails, cycle along quiet coastal roads, or simply relax and soak in the serene island atmosphere. With each island offering its own unique charm, the Shiwaku archipelago invites travelers to slow down, uncover hidden histories, and experience the harmonious blend of tradition and nature.
