Appreciation towards Kengo Kuma and Associates for providing the following description:

由隈研吾设计的饭山文化中心位于长野饭山县，建筑不远处便是2015年开通的北陆新干线车站。这个文化综合体由两个礼堂和一个社区中心组成，不同的功能区之间是宽敞的过道空间“Nakamichi”。建筑师以带有屋顶的拱形游廊“Gangi”为原型，将这种常见于日本多雪地区的传统建筑形式以现代建筑的手法演绎出来。建筑的屋顶部分由木材和钢材的混合结构支撑起来，此外也利用了本地的木材、夯实的土壤和当地生产的纸张。建筑师用朴实的材料和开放的空间营造出一种不常见于公建设施的温馨氛围。建筑的立面采用了COR-TEN耐腐蚀高强度钢和日本松木，起伏的造型让建筑与其后的绿色山林相得益彰，宁静安稳的形象与附近高速通过的铁路形成了鲜明的对比。

The town of Iiyama is located in Nagano prefecture, whose Japan Railway station lies on the Hokuriku Shinkansen line, which started its service in 2015. The project is a cultural complex of two halls and a community center, and we connected the spaces with an interiorized passage which we call Nakamichi.

We got a hint from roofed arcades called “Gangi”,  which can be found in snowy regions in Japan. Its intimate space formed by a wooden frame and “doma (earth floor)” was revived here as a modern version of Gangi.

The roof of Nakamichi is supported by mixed structure of wood and steel. The entire space is made of such elements as locally produced timber, soft and moist floor like natural earth, washi paper made by local craftsmen, and creates an atmosphere that could not be felt in a typical publicly-funded facility often described as a closed box.
The whole building is shaped like a hill and covered with a façade of COR-TEN and Japanese larch, morphing into the green rise at the back, making a contrast with the trains running nearby.
