The starting point was to open the east exit of Hoshakuji Station. The practice of Kengo Kuma aimed at connecting the west and east sides of the station, which had been divided by the railroad. It eventually meant the link between the west and the east of the town of Takanezawa, and between the station and Chokkura Plaza & Shelters, which architects designed in the east exit area. It is not a design of a station as a box, but is as an aperture. The aperture starts at its 'neighbor', Chokkura Plaza.

They first decided to preserve the old warehouse of Oya stone that had existed in the area. Then they took advantage of pores in Oya stone, and used them in the new structural system, in which steel frame and Oya stone are combined diagonally, and added the system to the warehouse. Following the design of this 'neighbor', they extended this diagonal skin to the other 'pore' or 'aperture', which is the station. By such extension and connection, the architets attempted to link not only the station's west exit and east exit, but also the station and its location.

In order to reduce the weight, lauan-made plywood was used for the structure, instead of Oya stone. By using wood, they wanted to revive the humane and warm atmosphere once any station building used to have. The touch of this station building would be conveyed further to the landscape of paddy fields and wooden houses in the town of Takanezawa.

"Our emphasis was that by creating 'pores', things could be pulled together and restore the community that had been long fragmented." Kengo Kuma
