In the shadow of modern Sapporo lies a buried truth: the Ainu, Hokkaido's indigenous people, whose voices were systematically silenced by Japanese colonizers in the 19th century
You are a lead surveyor for the Hokkaido Development Commission, dispatched to Sapporo in the late 19th century.
Governor Kuroda Kiyotaka has tasked you with overseeing the region's transformation
Discover Sapporo, Hokkaido's capital, where Meiji expansion sculpted an urban landscape between Ainu heritage and nascent modernity.
Your journey begins in front of the Sapporo Clock Tower, an Important Cultural Property of Japan. Erected in 1878, this 13.5-meter-high wooden tower served as the bell tower for the Northern Japanese Army's military drill ground, symbolizing the Meiji government's colonial establishment in Hokkaido. Here, you perceive the first ambitions for development, with the clock imported from the United States marking the time of a new era for the city of Sapporo. 300 meters away, the site of the former government building from 1881, demolished in 1911, recalls Hokkaido's first colonial administrative center (1871-1881), marking the Meiji expansion into Ainu lands.
Continue towards the Hokkaido Government Office, another Important Cultural Property of Japan. This Neo-Baroque building, constructed between 1888 and 1898, became the seat of the colonial government of Hokkaido. Its 15,000 m² area and 49-meter central tower testify to the administrative power deployed for the region's management. It was here that assimilation and development policies were orchestrated, shaping the destiny of Sapporo and its inhabitants. You feel the imprint of this era, where every stone laid told a story of colonization and territorial transformation.
The route then leads you to Odori Park, created in 1871 by Kiyota Hiroshi. This 1.5 km linear park, 45 to 80 meters wide, was designed as a public green space, central to Sapporo's planned urban development from 1869. It served as a demarcation between the western and eastern districts, a vital axis for the new city. Although modern, the Sapporo TV Tower, built in 1957 at the eastern end of the park, symbolizes Sapporo's post-war reconstruction and offers a view from 90.4 meters over this historic urban plan. The park has also hosted the Sapporo Snow Festival since 1950, a major event for the city.
The Soseigawa River, canalized in 1880 for urbanization, flows through the heart of Sapporo. Approximately 2.5 km long within the city, it was used for irrigation as early as 1870, demonstrating early engineering to support the city's growth. The Sapporo Beer Museum, opened in 1987, is in the immediate vicinity of the Clock Tower. It is housed in the former Sapporo Beer factory, built in 1890, which was Japan's largest at the time. This site is dedicated to the history of Sapporo Breweries, founded in 1876 by Seibei Nakagawa, a key player in Hokkaido's industrialization.
As you complete your exploration of Sapporo, you have traversed a century of history, from the Meiji colonial establishment to post-war reconstruction. Each monument, from the Clock Tower to the Government Office, through Odori Park and the vestiges of industrialization, tells a chapter of Hokkaido's transformation. This thematic circuit of Sapporo, following in the footsteps of pioneers and builders, offers you a unique perspective on the city's heritage, a blend of ambition and resilience, where the forgotten voices of the Ainu still resonate beneath modern edifices. It is a deep immersion into the history of Sapporo, a city that constantly reinvents itself.
