The museum building is intentionally constructed in the shape of a sail, serving as a landmark visible from the harbor.
Sasebo was designated as a Naval District in 1886, a primary catalyst for the city's urban transformation documented within the museum.
The collection includes detailed records of the decommissioned vessels that were once stationed at the Sasebo Naval Base.
The museum houses a specialized exhibit detailing the process of ship salvage and maritime rescue operations conducted by the JMSDF.
Some exhibits are presented on high floors to provide a direct visual perspective of the harbor where the actual naval base resides.
The JMSDF Sasebo Museum Sail Tower is a dedicated maritime history facility documenting the evolution of the Japan Maritime Self-Defense Force and the former Imperial Japanese Navy in Sasebo. Housed in a distinct seven-story structure designed to resemble a ship's mast, it provides a comprehensive overview of Sasebo's strategic development as a naval port. The exhibits utilize dioramas, historical artifacts, and multimedia displays to illustrate naval operations and the daily life of personnel. The museum functions as a research repository for naval archives and specialized regional history. Its location overlooks the Sasebo harbor, emphasizing the geographical link between the facility and the maritime infrastructure it documents. Visitors can examine tactical maps and authentic weaponry that defined the region's 20th-century history. The facility serves as the primary educational node for understanding the military heritage of Western Kyushu.
The observation deck level offers the best vantage point for panoramic shots of the Sasebo harbor and its naval vessels.
