Shinchiku Prefecture Office (now Hsinchu City Government)

The Shinchiku Prefecture Office (新竹州庁, Shinchiku Shūchō) is a landmark Japanese colonial-era government building standing at No. 120, Zhongzheng Road, North District, Hsinchu City, Taiwan. Built in 1925–27 and designated a monument in 1998 (now a National Monument, 國定古蹟), it is one of the best-preserved prefectural office buildings from the Japanese period in Taiwan and remains in administrative use as the Hsinchu City Government headquarters.

Historical Background: Shinchiku Prefecture

When Japan reorganized Taiwan's administrative divisions in 1920, the island was divided into five prefectures (州, shū) and two sub-prefectures (廳, chō; three from 1926). Shinchiku Prefecture (新竹州) was established with its seat at Shinchiku (present-day Hsinchu City), governing a vast area that encompassed modern-day Hsinchu City, Hsinchu County, Taoyuan City, and Miaoli County. Prior to the 1920 reform, the area had been administered as Shinchiku Chō (新竹廳) since 1901.

The existing administrative facilities were inadequate for the expanded prefectural government, prompting the colonial authorities to commission a new purpose-built office. Construction began in 1925 (Taishō 14); 1926 (Taishō 15 / Shōwa 1) is often given as the completion date, but the ridge-raising ceremony (上棟式) is recorded on 26 November 1927, after which the building came into use, and the entrance portico was extended in 1932 (Shōwa 7) to give the building its present imposing facade.

Architectural Features

The Shinchiku Prefecture Office exemplifies the 'Japanese-Western hybrid' (和洋混合, wayō kongō) style favoured for official colonial buildings in Taiwan during the Taishō and early Shōwa eras. The two-story structure is built of reinforced brick (加強磚造) on a U-shaped (ㄇ字形) floor plan, with the open end of the U facing the rear (north).

Key architectural elements include:

• Portico entrance: A projecting double-columned porte-cochère with a triangular pediment, added/extended in 1932, giving the main facade a monumental quality.
• Twin flanking towers: Short square towers rise above the roofline on either side of the central entrance, creating a symmetrical and authoritative composition.
• Exterior cladding: Red brick walls accented with grey washed-stone (洗石子) horizontal bands, window surrounds, and decorative cornices.
• Roof: A Japanese-style wooden-framed sloped tile roof (木架瓦造斜屋頂) sits atop the Western-style building body — the defining 'hybrid' feature.
• Interior corridors: Roman-arched hallways with columns, balconies on east, west, and south sides, and generous ceiling heights designed for natural ventilation in Taiwan's humid subtropical climate.

The overall effect balances Western neoclassical authority with Eastern architectural sensibility, characteristic of Japanese colonial civic architecture across Taiwan.

The Prefecture During the Second World War

As Japan's military campaigns expanded across the Pacific from 1937 onward, the Shinchiku Prefecture Office became the administrative hub for wartime mobilization across its vast jurisdiction. The prefectural governor (州知事) coordinated:

• Military conscription and labour mobilization: Organizing Taiwanese subjects for military service, labour battalions (軍夫), and industrial war production.
• Civil defence: Establishing air-raid shelters, blackout regulations, and neighbourhood watch associations (隣組) under the wartime community mobilization system.
• Resource allocation: Managing rice rationing, metal collection drives, and the requisitioning of materials for the war effort.
• Kōminka movement: Implementing the 'imperialization' (皇民化) policies that sought to assimilate Taiwanese into Japanese imperial subjects, including name-changing campaigns and Shinto shrine worship.

Shinchiku Prefecture held particular strategic significance due to the presence of the Shinchiku Airfield (新竹飛行場), a major Imperial Japanese Navy air base, which was consequently targeted by Allied forces.

On 25 November 1943, the United States Army Air Forces launched a surprise bombing raid on Shinchiku Airfield — one of the first American air attacks on Taiwan during the Pacific War. Subsequent Allied bombing raids struck Hsinchu City in 1944 and 1945, targeting military and railway infrastructure. The Prefecture Office building itself survived the war intact, owing to its sturdy reinforced-brick construction and its distance from primary military targets.

Postwar Transition

Following Japan's surrender on 15 August 1945, the Republic of China assumed control of Taiwan on 25 October 1945 (known as Retrocession Day / 光復節). The Shinchiku Prefecture Office was handed over to the new Chinese administration. Initially, it served as the Hsinchu County Government (新竹縣政府) office. In February 1946, when Hsinchu County's administrative seat was relocated to Taoyuan, the Hsinchu City Government (新竹市政府) moved in. After the county and city were merged in 1950 the county government returned to the building, and it has housed the city government again since the county government moved to Zhubei in 1989.

Heritage Designation and Preservation

On 23 June 1998, the Shinchiku Prefecture Office was designated a provincial monument by the Taiwan Provincial Government; after the provincial government was streamlined it was reclassified as a National Monument (國定古蹟), in recognition of its architectural excellence and historical significance as a representative example of Japanese colonial administrative architecture.

After being damaged in the 1999 Chi-Chi earthquake, the building underwent restoration from 2000 to April 2005 to recover its original appearance while accommodating modern civic functions. The surrounding plaza has been landscaped, and nighttime illumination highlights the building's architectural details.

Hsinchu City Art Gallery (新竹市美術館)

The Hsinchu City Art Gallery occupies a separate building nearby: the former Hsinchu City Hall (新竹市役所), a two-story red-brick building of about 1925 that is itself a municipal monument. It was converted into the Hsinchu City Art Gallery and Reclamation Hall (新竹市美術館暨開拓館) in 2007. In 2016, it was renamed simply the Hsinchu City Art Gallery (新竹市美術館), serving as a venue for contemporary art exhibitions and cultural events. This adaptive reuse demonstrates how colonial-era administrative buildings in Taiwan have been thoughtfully repurposed for cultural and civic functions.

Today, the Shinchiku Prefecture Office stands as one of the most significant surviving examples of Japanese colonial government architecture in Taiwan — a tangible reminder of the island's complex colonial history and its wartime role within the Japanese Empire.
