Yashima is a plateau mountain with an elevation of 292m, serving as a beloved symbol of Takamatsu City, Kagawa Prefecture. Its name originates from its unique shape, which resembles a roof. This topography is an andesitic lava plateau formed by volcanic activity approximately 12 to 15 million years ago, characterized by a distinct 'mesa' structure shaped by erosion.
Historically, Yashima is renowned as a vital military stronghold during the Genpei War (Jisho-Juhei War) at the end of the Heian period. It was a site where the Taira clan, supporting Emperor Antoku, retreated, leading to fierce battles with the pursuing Minamoto clan. Today, it is part of the Seto Inland Sea National Park, where rich nature, history, and beautiful landscapes coexist.
The history of Yashima is deep, with remains of Yayoi-period settlements and the ruins of Yashima Castle from the Asuka period. The legends of the Genpei War are inseparable from its identity, including the tale of Nasu no Yoichi shooting the fan target and the 'Funakakushi' (hiding of ships) where the Taira clan hid their fleet.
Religious significance is also profound, with Yashima-ji Temple, one of the 88 temples of the Shikoku Pilgrimage, located here. Legend says the temple was founded by the Chinese monk Ganjin. The main hall and the Eleven-faced Thousand-armed Kannon statue are designated as Important Cultural Properties of Japan. During the Edo period, the area was maintained and protected by the Takamatsu lords, establishing its cultural foundation.
The greatest draw of Yashima is the panoramic view of the Seto Inland Sea from the summit observatory. The view of islands floating in the calm sea alongside the Takamatsu cityscape is truly spectacular. Additionally, the 'New Yashima Aquarium' at the summit offers a rare experience of interacting with marine life atop a mountain.
Historical ruins are also a must-see, including reconstructions of the Yashima Castle gates and sites related to the legend of Nasu no Yoichi. The area blends history with nature, featuring lush forests of Japanese evergreen oak in the Hokurei area.
Yashima shows different faces throughout the seasons. The view is especially breathtaking on clear days when the Seto Inland Sea sparkles, or during sunset when the sky turns colorful. The scenery changes with the light of the sea and the city lights, making every visit unique.
In summer, the lush greenery and cool sea breezes make it ideal for hiking. Facilities like the aquarium and historical buildings offer stable enjoyment regardless of the season. At night, some areas and parking lots remain accessible until around 10:00 PM, allowing for a serene night view.
There are diverse ways to enjoy Yashima. History enthusiasts can explore the ruins of Yashima Castle and visit the temple to trace the footsteps of the Genpei War. Families often enjoy the New Yashima Aquarium, a popular spot for children to learn about marine life.
Nature lovers can utilize the well-maintained trails in the Hokurei zone for hiking. Walking through the evergreen oak forests provides a refreshing experience. Beyond just the view, visitors can observe the unique geological features of the lava plateau.
The foot of Yashima is surrounded by areas where you can enjoy Kagawa's local delicacies. Famous 'Udon' shops and restaurants serving 'Honetsuki-dori' (bone-in chicken) are scattered nearby. Its proximity to Takamatsu city makes it easy to integrate into a larger sightseeing itinerary.
Yashima is divided into the South Ridge (with tourist facilities) and the North Ridge (rich in nature). While main paths are well-maintained, sturdy walking shoes are recommended for hiking.
