Guide
Yashima is a 292-meter-high plateau that serves as a symbol of Takamatsu City, Kagawa Prefecture. Its name comes from its distinctive roof-like shape. This landscape is an andesitic volcanic plateau formed approximately 12 to 15 million years ago, characterized by a unique "mesa" topography shaped by erosion.
Historically, Yashima was a vital military stronghold during the Genpei War (the Jisho-Juwa War) at the end of the Heian period. It was a site of intense conflict where the Taira clan, fleeing with Emperor Antoku, was pursued by the Minamoto clan. Today, it is part of the Seto Inland Sea National Park, where rich nature and history coexist with stunning scenery.
The history of Yashima is deep, with remains of settlements from the Yayoi period and the ruins of Yashima Castle from the Asuka period. The Genpei War legends are central to its identity, including the tale of Nasu no Yoichi shooting an arrow at a fan and the "Funakakushi" where the Taira clan hid their ships.
Spiritually, the area is home to Yashima-ji, a temple associated with the Shikoku 88 Temple Pilgrimage. Legend says the monk Ganjin was involved in its founding. The temple's main hall and the Eleven-faced Thousand-armed Kannon statue are designated as Important Cultural Properties. During the Edo period, the area was preserved and developed by the Takamatsu lords, building a strong cultural foundation.
The greatest draw of Yashima is the panoramic view of the Seto Inland Sea from the summit. The sight of islands floating in the calm sea alongside Takamatsu City is truly spectacular. Additionally, the summit features the rare Shin-Yashima Aquarium, where you can interact with marine life high above the sea.
Historical-lovers will appreciate the reconstructed gates of Yashima Castle and the sites related to the legends of Nasu no Yoichi. The area also offers a sense of timelessness through Yashima-ji Temple. For nature enthusiasts, the northern area features lush forests of nutmeg trees, perfect for a refreshing walk.
Yashima offers different charms in every season, but it is especially beautiful on clear days when the Seto Inland Sea sparkles, or during the golden hour of sunset. The view from the Yashima Skyway changes beautifully with the shifting colors of the sea and the city lights at night.
Summer is a wonderful time for hiking due to the refreshing sea breezes and lush greenery. Facilities like the aquarium and historical sites remain popular year-round. Since the parking areas and surrounding facilities are open until around 22:00, you can also enjoy the tranquil atmosphere of the night scenery.
There are diverse ways to enjoy Yashima. History enthusiasts can trace the paths of the Genpei War, visit the castle ruins, or pray at Yashima-ji. Families often flock to the Shin-Yashima Aquarium for an engaging experience with marine life.
Nature lovers can explore the well-maintained trails in the northern zone. Walking through the nutmeg forests is a great way to refresh both mind and body. As you walk, you can observe the unique geological features of the volcanic plateau and feel the history of the earth.
At the foot of Yashima, you can enjoy Kagawa's famous local cuisine. The area is dotted with restaurants serving Sanuki Udon and the famous chicken-based dish, Honetsuki-dori. Its proximity to Takamatsu City makes it easy to combine a visit to Yashima with other sightseeing plans.
Yashima is divided into the South Ridge (with tourist facilities) and the North Ridge (rich in nature). While many paths are well-maintained, sturdy walking shoes are recommended if you plan to use the hiking trails. Carrying water and sun protection is also advised.
