About Chiyogasaki Battery

Chiyogasaki Battery is a Western-style battery constructed by the army on Hiraneyama, where the Aizu Domain built a fortress in the late Edo period. Due to its well-preserved original appearance, it has been designated as a national historic site, alongside Sarushima Battery, as it holds significance in understanding Japan’s modern military and fortress construction techniques. It has also been recognized as a component cultural property of Japan’s heritage.

Moreover, it serves as a satellite facility for the “Yokosuka Route Museum,” which connects the history, culture, and nature of Yokosuka City through various routes, turning the entire city into a vast museum experience.

Atmosphere of the Underground Facilities

One of the distinctive features of the Chiyogasaki Battery Ruins is the opportunity to explore the underground facilities, including the gun emplacements and associated ammunition depots. The ambiance of these subterranean spaces is sure to provide a unique and photogenic experience.

Facing the Sea

Perched atop a hill approximately 65 meters above sea level, the Chiyogasaki Battery Ruins offer stunning views of the surrounding seascape. While the ascent to the battery ruins involves navigating uphill slopes, the reward is panoramic vistas overlooking the Uraga Strait of Tokyo Bay. On clear days, you can even catch sight of the Boso Peninsula nearby.
During chilly winter days, looking out over the Kuriohamma Bay side may afford views of majestic Mount Fuji in the distance.
