Former National Raw Silk Conditioning Houses, Historic former silk inspection house in Shinminato, Kobe, Japan

The Former National Raw Silk Conditioning Houses is a four-storey reinforced-concrete building, five storeys in part, completed in 1932 in Kobe's Shinkō district. Its exterior is unified by Gothic motifs, and it stands next to the former Kobe Municipal Raw Silk Conditioning House. Since 2008 it has formed the New Wing of the Design Creative Center Kobe (KIITO), with a hall, galleries and project spaces.

Built in 1932, the facility became crucial for testing raw silk quality before it could be exported worldwide. It marked a shift in how Japan managed its silk production, moving from local practices to standardized international procedures.

The building stands in the Shinminato district beside the Kobe Customs House and the former Kobe City Raw Silk Conditioning House, and since the 2008 closure of the testing facility it has served as the annex of the Design and Creative Center Kobe (KIITO). Its floors now hold a hall, galleries A and B, a kitchen, project spaces and a fabrication workshop.

The building stands in the Shinkō district of Chūō-ku, Kobe, a five-minute walk from the Port Liner Trade Center Station and about twenty minutes on foot from the Sannomiya stations. It now forms the New Wing of the Design Creative Center Kobe (KIITO), alongside the older former Kobe Municipal Raw Silk Conditioning House. The New Wing holds a hall, galleries A and B, a kitchen, project spaces and a fabrication workshop.

The building was designed by Akira Oshio, an army engineer who also worked on the chemical analysis building of the former Osaka Arsenal and the former Ibaraki Prefectural Government building. It stands next to the former Kobe Municipal Raw Silk Conditioning House, and since the Kobe City purchase both serve as the New Wing of the Design and Creative Center Kobe (KIITO).
