Yashima

Yashima is a distinctive flat-topped, roughly table-shaped plateau rising abruptly from the coast just east of central Takamatsu, and it combines panoramic views, dramatic history, and a sacred pilgrimage temple in one memorable destination. The name means 'roof island,' for the plateau once was an island before the shallow channel silted up, and its steep sides and level summit give it an unmistakable silhouette. From the top, visitors are rewarded with commanding vistas over the island-studded Seto Inland Sea in one direction and the city of Takamatsu and the Sanuki mountains in the other.

The plateau is steeped in one of the most famous episodes of Japanese history. In 1185, during the Genpei War between the Taira and Minamoto clans, the Battle of Yashima was fought here, and the waters and shores around the plateau are woven through the epic Tale of the Heike. The most celebrated moment is the legend of the archer Nasu no Yoichi, who, at the request of the taunting Taira, shot down a fan mounted on a pole atop a rocking boat with a single arrow — a feat of skill immortalized in literature and art. Sites around Yashima commemorate the battle, and the history adds a layer of romance to the sweeping scenery.

Atop the plateau sits Yashima-ji, the 84th temple on the famous 88-temple Shikoku pilgrimage circuit associated with the monk Kobo Daishi. The temple's main hall, treasure house, and grounds draw white-clad pilgrims and casual visitors alike, and its Tanuki shrine, dedicated to a legendary shape-shifting raccoon dog said to protect the mountain, is a local favorite. The temple lends the summit a serene, spiritual atmosphere amid the viewpoints.

From the western edge of the plateau, a popular tradition is kawarake-nage, in which visitors fling small unglazed clay disks out over the cliff toward the sea, a ritual believed to cast away misfortune — and a genuinely fun thing to do while taking in the view. This western overlook is also a superb spot to watch the sun set over the Inland Sea, its light scattering across the water and silhouetting the islands. A newer observation deck and rest facilities have enhanced the summit experience.

At the foot of the plateau lies Shikoku Mura, an excellent open-air museum of relocated traditional buildings, making it easy to combine the two. The summit is reached by a shuttle bus from Yashima Station, or on foot via the old stone pilgrim path for those wanting a hike; the Kotoden railway connects the area to central Takamatsu.

With its blend of natural spectacle, legendary history, active pilgrimage temple, and lucky rituals, Yashima offers a richly layered half-day out. Clear weather brings the best views, and a late-afternoon visit timed for sunset over the Seto Inland Sea is especially rewarding, capping a day exploring the eastern edge of Takamatsu.
