The structure was restored by dismantling into some part which revealed the history or the process of construction during the works. It was also the first example of carbon fibre application into a Japanese conservation procedure.

[What it is]

Kumagawa Rail Road facilities were constructed in the Taisho period and are still in use today, largely maintaining the railway standard design of the period. For its rarity and its value as a factor contributing to the local historic landscape, 19 facilities including a bridge and a station building were nationally registered as cultural properties in December 2014.

[What we did]

JCHC conducted a basic survey and produced registration documents. It is a part of local initiative to regenerate and revitalize the railroad. This is an example of successfully raised local people's motivation for protection and utilization, by recognizing them not just as transportation facilities but also as cultural property.

[What we did]

In collaboration with architect Kenji Hirose, we designed the museum building, which turned out to be Hirose's last work. The simple steel structure with gentle-sloped roofs is designed complying with the natural conditions such as cold winter and strong sea breeze. The inside liberating space is realized by the cast iron columns and wooden roof frames.
