designed by architect kengo kuma, this community complex has built to coincide with the completion of a high speed railway line connecting japan’s hokuriku region. located in iiyama, a town located in the nagano prefecture, the ‘iiyama cultural hall’ features two large halls in addition to a civic center, providing the local population with a place to congregate and socialize.

each space is connected via an intimate passageway that references ‘gangi’ — roofed arcades often found in the country’s snowy regions. the roof canopy is supported by a hybrid timber and steel structure, while other regionally sourced materials, such as locally produced washi paper, help contribute towards creating an inviting and hospitable atmosphere.

the three distinct volumes are independently organized across the plot, each offering pleasant external views. the largest of the halls is a flexible area that primarily serves as a performance space. developed to be as open and as welcoming as possible, the site is oriented towards the town center, and forms a direct relationship with the surrounding environment.

the angular building has been covered with a façade of corten and japanese larch. the scheme seeks to become a catalyst for iiyama, benefiting from the positive impact the train line will have on the newly connected town’s economy. see designboom’s previous coverage of the project here.
