Tsuchibushi Strait

Overview

Tsuchibushi Strait is a strait separating Maejima Island and the main island of Shodoshima, in Kagawa Prefecture. Its most distinctive feature is its narrowness. At its narrowest point, it's only 9.93 meters wide. Because of this, it was certified by the Guinness Book of World Records in 1996 as the "world's narrowest strait," attracting global attention. Crossing Tsuchibushi Strait offers a unique sensory experience due to its narrowness, along with the enjoyment of the surrounding lush nature. Lush mountains and the blue sea spread across both sides of the strait, allowing you to enjoy a stroll while feeling the sea breeze. The Tonosho Town Office, located just across the strait, issues a crossing certificate—a perfect souvenir of your trip. Tsuchibushi Strait is one of Shodoshima's leading tourist spots and attracts many visitors. Experience the mystery of the world's narrowest strait for yourself by visiting Tsuchibushi Strait.
