Tokyo University of Mercantile Marine Administration Building: A Library Shaped Like a Ship
Across from Building 1 stands a smaller two-story structure that goes today by the name Administration Building, though it began life with a different purpose. When the campus was rebuilt after the Great Kanto Earthquake, this building went up in 1932 (Showa 7), at the same time as its larger neighbour, and it opened as the school library. Its outer walls wear the same scratch tile, and its detailing borrows the vocabulary of Building 1, so the two read clearly as siblings from a single campaign of reconstruction.
The building is of reinforced concrete with a floor area of about 400 square metres. What people tend to remember is its form, which is said to have been conceived with the image of a ship in mind, a fitting idea for a school that sent its graduates to sea. The clearest expression of that idea is at the back, where a rounded section projects outward like the curve of a hull or a stern. On a campus of mostly rectangular buildings, that curve gives the former library a profile you can pick out at once.
Why It Is Protected
The building is a Registered Tangible Cultural Property, listed on 12 December 1997 and announced on 8 January 1998 under registration number 13-0005. It was registered as a model of design, the same criterion applied to Building 1 and Building 2. Registration, the lighter of Japan's two heritage frameworks, is well matched to a structure that has stayed in continuous institutional use rather than being set aside as a monument.
Taken with Building 1, this former library shows how a single design language was carried across a campus. The shared tile, the related detailing, and the deliberate curve at the rear are not accidents but choices, the work of the Ministry of Education and the Ministry of Finance shaping a group of buildings that would speak with one voice. The listing recognises that coherence, and the ship-like rear that gives the group a touch of wit.
Seeing It Today
Walk around to the back if you can, because the curved projection is the detail worth the trip and it is easy to miss from the front. From there the ship idea stops being a caption and becomes something you can see in the wall itself. The building now houses an advanced science and technology research centre, its interior long since adapted to laboratories, so the rooms are not open, but the exterior tells its own story.
The Administration Building sits within the open grounds of the Etchujima campus, which belongs to Tokyo University of Marine Science and Technology and can be entered on foot when the gate is up. Reading it beside Building 1 and then walking on to the Meiji Maru, the Important Cultural Property ship kept nearby and open to board without charge, lets you follow the maritime theme from a library shaped like a hull to a hull you can actually stand on.

Q&A
- What was this building originally used for?
- It was built in 1932 as the school library, at the same time as Building 1. It later took on administrative and research functions and is now used as an advanced science and technology research centre.
- Is it really shaped like a ship?
- The building is said to have been designed with the image of a ship in mind. The clearest sign is the rounded section that projects from the rear, which suggests the curve of a hull.
- Why does it look so much like Building 1?
- The two went up together during the post-earthquake reconstruction, share the same scratch-tile finish, and were shaped by the same government offices. They were meant to read as a matched group.
- Can I go inside?
- No. It is a working research building and its interior is not open to visitors. You can view the exterior, including the curved rear, from the campus grounds when the gate is open.
- What is the best thing to pair it with?
- Building 1 across the way for the shared design, and the Meiji Maru a short walk on, an Important Cultural Property ship open to board for free.
