Buildings of Hashima
Architectural documentation for the HashimaXR reconstruction
Reconstructing a Vertical City: Hashima Island contained over 70 numbered structures within its 6.3 hectares, including Japan's first reinforced concrete apartment building. The documentation gathered here represents the research foundation for 3D reconstruction, combining CAD data, archival photographs, and architectural surveys.
Buildings on Hashima served multiple functions in the hyper-compressed urban environment: residential apartments, mining infrastructure, community facilities, religious sites, and commercial spaces. Many buildings were connected by elevated walkways and underwent multiple expansions over the island's operational period (1890-1974).
Landmark Buildings
Historically SignificantGlover House
Japan's first reinforced concrete apartment building. Originally 4 stories, expanded to 7 shortly after completion. The L-shaped building has a central atrium and was reconstructed in 1953 by replacing lower-floor steel bars while leaving upper floors intact.
Named for a rumored connection to Thomas Blake Glover. By closure, it served as housing for subcontractors rather than its original use as miners' housing.
Hōkoku-ryō (報国寮)
Hashima's largest apartment building. U-shaped structure built in phases: North wing (7F, 1945), expanded to 8-9F (1947), East wing (9F, 1949), rooftop kindergarten (1953), South wing "New 65" (10F, 1958).
The "New 65" south wing was the island's tallest building with private flush toilets, while north/east wings used communal facilities.
Hashima Shrine
The highest point on the island. Unusually constructed of concrete rather than traditional wood. Site of the annual Sanjinsai (Mountain God Festival) held on Sundays around April 3rd.
The sight of islanders running down the "stairway to hell" while carrying the portable shrine (omikoshi) was a unique spectacle of festival culture in an urban environment.
Shōwakan (Cinema)
Art Deco movie theater with balcony seating. Company-operated with two screenings from 6pm on weekdays. Films premiered here before Nagasaki city, attracting visitors from off-island.
Also hosted theatrical performances and concerts. Declined with television proliferation, shifted to adult films, closed 1970. Used as ping-pong hall in final years. Mostly destroyed by 1991 typhoon.

Hummingbird House (ちどり荘)
Municipal housing for teachers and school staff, reflecting the island's investment in education for the children of workers.

Senbukuji Temple
Buddhist temple combined with company housing. Served the spiritual needs of the community alongside the Shinto shrine at the island's peak.
Commercial Zone
Shops & ServicesCommissary
Company store/commissary combined with miners' housing. Essential retail facilities in a community entirely dependent on supplies brought by ship.
Pachinko/Mahjong Parlor

Snack Pub / Ryokan
Company housing that also contained hospitality businesses: snack pub Hakusuien and Ryokan Seifusō. Served both residents and occasional visitors.
Subcontractor's Kitchen
Wooden structure (unusual on the concrete island) that served as housing and kitchen for subcontractor workers. The Kinoshita family lived here briefly in 1959.
Mining Zone
Industrial InfrastructureColliery Facilities
The surface facilities of the colliery occupied the flat southwestern part of the island—approximately 40% of habitable space. These buildings housed the machinery and infrastructure supporting the undersea mine.
No. 2 Pit Winding Room
Winding room for the No. 2 Pit shaft, housing the machinery that raised and lowered the mining cage carrying workers to and from the undersea tunnels.
No. 2 Pit Tunnel Entrance
Entrance to the No. 2 Pit tunnel system. The mine extended approximately 1 kilometer below the island and several square kilometers under the seabed.
No. 2 Pit Sorting Machine
Coal sorting machinery for the No. 2 Pit, where coal was graded and processed before loading onto ships.
Loading Infrastructure
Loading cranes (Q), dolphin pier (R), and loading pier (S) facilitated the export of coal and import of supplies—the island's lifeline to the outside world.
Conveyor Belt / Coal Pile
Coal conveyor systems and storage piles. The belt conveyor (ベルトコンベアー) moved coal from processing to loading facilities.
Recreation
Leisure FacilitiesSwimming Pool
Swimming pool for residents. Children swam here and in the sea during summer months—one of the few recreation options on the densely built island.
Tennis Court
