This building was built in 1896 as a powerhouse in this place (Nishidomari-machi, Nagasaki City), concurrently with the formation of the Temporary Taiwan Telegram Construction Department of the Army Ministry of Japan.

The powerhouse (engine room) was equipped with a steam boiler, a pump for filling or discharging water, equipment to move cables, and it had played an active role until 1968 as a power source to move cables between cable laying vessels and four cable storage reservoirs (, which were called “submarine cable storage reservoirs” at that time,) built at the same time.

This building built in the Meiji period was also extremely deteriorating, and it was supposed to be demolished in 1968. However, the year 1968 happened to be the 100th anniversary year of the Meiji period, and the Nagasaki Prefectural Board of Education requested us to preserve the building, saying, “We would like to ask the building to be preserved because the red brick building was one of a few remaining buildings built by means of the Western-style building techniques introduced into Japan in the early Meiji period.” As a result, it was determined to preserve the exterior of the building as it was.

After that, the building was left as it was for eight years until 1975. Then, it was decided to exhibit various materials as the “Submarine Cable Museum” by using this valuable building to pass on the historical records of the submarine cable business to the next generation. Finally, the museum opened in May 1977.
