We explore the city of Sasebo in this edition, revealing its hidden history and cultural charms.

What is Japan Heritage Naval Stations—Yokosuka, Kure, Sasebo, and Maizuru?

During the Meiji period, Japan selected four favorable natural ports—Yokosuka, Kure, Sasebo, and Maizuru—as national projects for constructing naval stations and establishing the Naval Stations, the headquarters of the former navy, to prepare a naval defense capability on par with the Western powers. The once quiet farming and fishing village transformed rapidly into a city that spearheaded Japan’s modernization efforts, drawing the latest technology of the time and the swift development of infrastructure such as water supply and railroads. Many of these facilities are still in operation more than a century later, and the underlying spirit of a bygone era can be felt on a stroll through the city.
This dynamic story was certified as a Japan Heritage Site in 2016 as Naval Stations—Yokosuka, Kure, Sasebo, and Maizuru—Dynamic cities for experiencing the centers of Japanese modernization.

Five Notable Japan Heritage Spots in Sasebo

Sasebo City is dotted with an overwhelming number of impressive remains that are still in active operation. Here are a selection of unique spots around Sasebo where you can get a feel of the pulse of history.

1. Old Sasebo Wireless Transmission Facility (Hario Radio Tower) [Component Cultural Property]

Built in 1922, this longwave communication facility is designated as a national important cultural property. The three radio towers that stand 136 meters tall are the oldest freestanding concrete radio towers in Japan. They are the culmination of the results of research gathered by the engineers of the Sasebo Naval Station since the Meiji period, and are also the foundation of modern concrete technology. The overwhelming scale and beauty of the towers are truly achievements of the technology of the time. Soaring into the sky, the towers convey to visitors the powerful dynamism of modernization.

2. Remains of the Imperial Japanese Army Sasebo Fortress Marude-yama Battery Observatory [Component Cultural Property]

One of five army batteries was built around the city to protect the port, with the main battery (built in 1901) comprising an observation post, a howitzer position, and a cannon position. Among them, the armored canopy of the observatory site is one of the most precious remains, existing in only two places in Japan. Today, the area has been developed as a trail course, where visitors are able to take in the stunning views of Kujuku Islands as well as feel the power of the battery remains. Since most of the tour is on foot, comfortable sneakers are recommended.

3. Sasebo Naval Station Triumphant Return Memorial Hall (Sasebo Citizens’ Cultural Hall) [Component Cultural Property]

This magnificent building was constructed in 1923 to commemorate the service of naval vessels belonging to the Sasebo Naval Station Office during World War I. The contrast between the massive walls and white stone is simply stunning, and the building is a national registered tangible cultural property. After being returned from the U.S. military following World War II, the building was revitalized as the Sasebo Citizens’ Cultural Hall. The site where naval ceremonies were once held is now cherished as a venue for civic cultural activities such as concerts. The second-floor gallery displays a model of the destroyer “Yukikaze,” constructed in Sasebo, and panels showcasing the modern history of Sasebo. The building is a heritage that has survived the turbulence of history and continues to support the culture of the city.

A massive crane that was imported from England and completed in 1913—it is a national registered tangible cultural property. With an overwhelming size of 62 m in height, 81 m long rotating section, and one of the world’s largest lifting capacities, it was once the workhorse of the naval shipyard. An extremely rare industrial heritage, there are only three of the same type existing in Japan, and only ten remaining around the world. The sight of the crane that remains in active operation is a source of pride for the shipbuilding town of Sasebo, and is a familiar landmark symbolizing the scenery of the port.

5. Mukyudou (naval defense corp, guard battery group) [Component Cultural Property]

During World War II, teachers and students of the then Miyamura Elementary School spent about two years hand-building this huge air raid shelter. Inside features classrooms, teacher’s desk, and even a kitchen area, food storage, and toilets for use during emergency shelter, with intricate construction of such a high level of quality that it is hard to believe it was built by children. A precious historical heritage that conveys the severity of wartime conditions at the time, and the resilience of the children who did everything to survive—Mukyudou provides a way to appreciate just how precious peace is.
