The Akishio submarine was transported from the harbor to its permanent land-based display pedestal using a specialized heavy-lift vessel and a rail-based slide system.
The museum interior uses a 'submerged' lighting design to simulate the feeling of being underwater.
The submarine on display, the Akishio, served in the JMSDF for nearly 20 years before its conversion into a museum piece.
The museum complex is positioned to overlook the active Kure naval shipyards, often providing views of modern warships in the harbor.
The JMSDF Kure Museum's official nickname, 'Iron Whale,' refers to the massive silhouette of the Akishio submarine rising from the museum's concrete base.
The JMSDF Kure Museum, known as the 'Iron Whale Museum,' is the only facility in Japan where visitors can board a retired actual submarine. The museum features the Akishio (SS-579), a Yushio-class submarine that was decommissioned in 2004 and transported onto land for public exhibition. The interior of the submarine preserves the original crew quarters, bridge, and sonar equipment. The main building focuses on the history of the Japan Maritime Self-Defense Force and the evolution of mine warfare technologies. Visitors walk through three floors of exhibits detailing mine countermeasures and the history of the Kure Naval District. The structure is physically connected to the Yamato Museum via a pedestrian walkway, creating a comprehensive maritime history complex.
The exterior viewing platform that allows you to capture the entire length of the Akishio submarine hull against the harbor backdrop.
Visit the Yamato Museum first to purchase a combined view, or simply transition between the two sites as they are adjacent.
Pay close attention to the narrow hatchways when boarding the submarine, as the interior spaces remain in their original, compact military configuration.
Photography is strictly prohibited in certain sensitive areas of the submarine interior; look for signage before using your camera.
Do not attempt to touch the control panels or technical equipment inside the submarine, as they are fragile historical assets.
Closed on Tuesdays. If a national holiday falls on a Tuesday, the museum typically closes the following Wednesday.
Avoid bringing large bags or bulky backpacks, as the interior of the submarine has very tight corridors and ladders.
