Mashū-maru is a well-preserved former train ferry that once connected Honshu and Hokkaido on the historic Seikan route, before the opening of the Seikan Tunnel. Today it functions as a memorial museum and a striking example of Japan’s maritime and transport history. The exhibition includes original crew uniforms, navigation and engine equipment, safety gear, bells, and detailed materials documenting the ferry service that operated here from 1908. Highlights include the preserved bridge and control room, as well as passenger seating areas that clearly evoke long-distance travel in mid-20th-century Japan. The open deck was closed, most probably because it is considered not safe in winter, but even from inside views of Hakodate Port were awesome. Most explanations are in Japanese, with some English descriptions available, though not consistently throughout the exhibition. That said, with modern translation tools, this does not pose a real obstacle for visitors who are genuinely interested in the subject. Museum is open from 9 am. Entrance fee is 500 yen for adults.

I decided to visit this ship since I had some time. To get on board, you have to climb a long flight of metal stairs—it’s not like you can just walk straight from the land. At the top, there’s a small souvenir shop. I thought the ticket counter was beyond the shop, so I almost tried to leave through the door before I noticed the counter on my right. I’m sure the staff thought I was trying to sneak in without paying, but that wasn’t the case! When I visited, it wasn’t very crowded, and honestly, there isn’t much to see on the ship—it’s quite old. The most fun part was the photo prop section, where you can try on any of the costumes on display and take your own photos. There’s no pushy photographer trying to make you buy photos, which was a relief. The view from the ship was also quite unique and worth enjoying.

Mashū-maru (摩周丸) memorial ship stands as a striking floating monument to Japan’s post-war transit history. Before the engineering marvel of the undersea Seikan Tunnel opened in 1988, connecting Honshu and Hokkaido meant braving the treacherous Tsugaru Strait by boat. The Seikan Renrakusen (train ferries) weren't just passenger vessels—they were engineered to carry entire freight trains directly inside their lower decks. Today, the Mashū-maru serves as a hands-on museum dedicated to that era. One of the absolute highlights is the degree of access visitors get. You can walk straight onto the ship’s bridge, complete with original radar scopes, telegraphs, radios, and nautical controls. Unlike many museums, you’re encouraged to touch the dials, step up to the helm, and take in panoramic views of Hakodate Port. Seeing the massive vehicle tracks inside the belly of the vessel brings home the technical complexity of loading rolling stock onto a sea vessel subject to tides and rough waves. Fans of maritime signaling will appreciate the radio room where you can practice sending Morse code, sound nautical horns, and explore intricate dioramas of the ferry fleet's operations. Preserved seating areas, including 1st-class lounges and Japanese-style carpeted seating areas, offer a fascinating glimpse into 1960s–1980s travel culture. The Mashū-maru offers a charming, authentic alternative to conventional indoor museums. It provides crucial historical context for how Hakodate developed as the primary gateway to Hokkaido. Given its incredibly low entry fee and proximity to the station and Hakodate Morning Market, it’s a highly recommended stop on any Hakodate itinerary.

This is a must-do when visiting Hakodate - a wonderful hands-on experience for all ages. Great views of the bay and city and very much a highlight of our visit. A small fee and value for money.

Fascinating museum and clearly this is a major activity. Artwork is brilliant and engineering of the float exquisite.
