Sarushima Island

Overview

Sarushima Island, a deserted island in Tokyo Bay, is a captivating spot where you can escape the urban hustle and bustle and immerse yourself in nature and history. The island boasts historical structures, including Japan's first coastal fort, built by the Edo shogunate, and the Sarushima Battery, part of the Tokyo Bay Fortress constructed during the Meiji era. These structures stand as testaments to their crucial role in defending Tokyo Bay. In 1847, during the late Edo period, the shogunate built a coastal fort on Sarushima Island to protect Edo (present-day Tokyo) from foreign threats. This was the first such fort in Japan. Later, during the Meiji era, it came under the jurisdiction of the Army and Navy Ministries, leading to the construction of the Sarushima Battery, a massive fortification designed to repel enemy ships. Fortunately, it was never used in actual combat and now stands as a precious historical relic, preserved in its original state. Beyond these historical structures, the island offers abundant natural beauty, with unique rock formations, caves, and lush forests. The Sarushima Battery, located on the southern part of the island, is rumored to have been the inspiration for the movie "Castle in the Sky," making it a popular destination for anime fans. Sarushima Island is a true "urban oasis," a perfect place to enjoy both history and nature. In recent years, it has become a popular spot for families and couples, offering activities such as swimming, barbecues, fishing, and leisurely walks. Though a small island in Tokyo Bay, Sarushima is a treasure trove of history and natural beauty—a true "island paradise."
