Shiinoki Cultural Complex, Ishikawa Prefecture, Cultural complex in Hirosaka, Japan

Shiinoki Cultural Complex occupies the former Ishikawa Prefectural Government Building in Hirosaka, Kanazawa. Its long facade is clad in tan scratch tile from Tajimi, divided into tall bays by pale stone strips, with stacked dark windows; the upper storeys are pale grey. The right end steps forward as a lighter block with a round-arched entrance, and the flat roofline carries three thin flagpoles.

Completed on 8 June 1924 as the Ishikawa Prefectural Government Building, it was the first reinforced-concrete building in the prefecture and the oldest reinforced-concrete prefectural office in Japan. It was designed by Kenkichi Yabashi, who also worked on the National Diet Building. The prefectural offices moved to Akanemachi in 2003, and the renovated building reopened on 10 April 2010. It was registered as a Tangible Cultural Property on 24 June 2021.

The name comes from the shiinoki (chinquapin) trees flanking the entrance, a pair about 300 years old and a national natural monument called Dōgyō no Shiinoki. The formal name, Ishikawa Prefectural Government Memorial Shiinoki Guest Hall, was chosen from 1,200 entries; the hiragana spelling was meant to convey warmth. Today the hall hosts exhibitions, seminars and a café-brasserie by Paul Bocuse.

The complex sits on the south side of Kanazawa Castle Park at Hirosaka 2-1-1, a short walk from the Hiroshaka/21st Century Museum bus stop and about five minutes on foot from Korinbo. The Kanazawa Castle Park side is glazed, while the main front facing the city hall keeps the 1924 facade. The building has a base-isolation structure and two elevators added in 2010.

The two stone oak trees on the grounds are estimated to be around 300 years old, meaning they were already standing long before the building was constructed. It is rare to find trees of that age in the center of a city like Kanazawa.
