Kankakei, Shodoshima, Shozu, Kagawa, Japan
The second largest of the Inland Sea’s islands, mountainous and rural Shodo Island is famous for its Kankakei Gorge, where maple and gingko trees blaze in a colorful display each fall, as well as the fine beaches along its 126 kilometers (78 miles) of coastline. The island’s name means “small bean,” but it is, perhaps surprisingly, better known as a center for olive cultivation. Just across the water in the port of Takamatsu, on Shikoku, the world’s first all-glass lighthouse is a big hit with visitors. After dusk falls, it is illuminated from within by red lights, making it not just a beacon for ships but a favorite of photographers.
