Sapporo Chikaho Underground Walkway

Officially the Sapporo Ekimae-dori Underground Pedestrian Space, and known to everyone as "Chikaho," this heated underground walkway is one of the quiet engineering triumphs that make winter in Sapporo not merely survivable but comfortable. Opened in 2011, it runs for about 520 metres directly beneath Ekimae-dori, the main north-south avenue, connecting the vast underground concourse of Sapporo Station at one end with Odori Station and Odori Park at the other. From those two hubs it links onward to the older Pole Town and Aurora Town malls, so that on a bitter January day a visitor can travel across the entire commercial core of the city—from the station shopping complexes to Susukino—without once stepping outside into the snow.

Sapporo receives roughly five to six metres of snowfall in an average winter, more than almost any other city of its size on the planet, and the Chikaho is the municipal response to that reality. Wide, bright and kept warm, it fills each morning with commuters, shoppers and students moving briskly between offices, department stores and subway lines. But it is more than a tunnel. Along its length run galleries and open plazas designed to be used as public space: the "Kita San-jo Hiroba" and other widenings regularly host pop-up shops, seasonal Hokkaido food fairs selling everything from Yubari melon to fresh dairy, craft markets, tourist-information counters, art exhibitions and community events. Digital signage and information desks make it a natural orientation point for first-time visitors.

Because it threads beneath the busiest part of the city, the Chikaho is also the most convenient way to reach a surprising number of sights. Direct underground exits deliver you to the doorstep of major department stores, the Sapporo Grand Hotel district, the government and business quarter, and—crucially—to Odori Park, the long green ribbon that hosts the Sapporo Snow Festival, the summer beer gardens and the White Illumination in December. During the Snow Festival in particular, when Odori fills with monumental ice and snow sculptures and the crowds are enormous, the heated walkway becomes an essential circulation route.

For the traveller, the practical value is obvious, but it is worth slowing down rather than simply using it as a shortcut. The rotating events mean there is often something to browse—a regional producers' fair, a student art show, a seasonal illumination—and the people-watching is a window into everyday Sapporo life. Free public Wi-Fi, clean restrooms and clear multilingual signage make it easy to use.

Entry is free and the walkway is open from before six in the morning until after midnight, closing only in the small hours. You can join it from inside Sapporo or Odori station, or from any of the numbered street-level exits along Ekimae-dori. It is not a monument or a museum, but understanding the Chikaho—and the network of underground malls it connects—is the single most useful piece of local knowledge for anyone visiting Sapporo in the cold months.
