The Spring Traverse: Sounkyo to Kushiro

A fast-paced journey through Hokkaido's ephemeral spring landscapes.

Hokkaido's spring runs late and fast. Snowmelt off the Daisetsuzan range turns the Ishikari River into a genuine whitewater run for about six weeks, moss phlox turns entire hillsides shocking pink for roughly the same short window, and Shiretoko's most-visited walking trail switches from open access to guided-only exactly when the bears wake up and start moving. This trip is built around that compressed calendar, moving east across Hokkaido entirely by private car with an English-speaking driver, taking in mountain passes and lakeside viewpoints at whatever pace the group wants rather than a train timetable.

It starts in central Hokkaido, moving to the mountains at Sounkyo, a gorge town with a genuine rafting outfitter and two waterfalls ranked among Japan's best, then heads east toward Abashiri, catching Higashimokoto's moss phlox hillside and, if timing allows, the tail end of cherry blossom season at a lesser-known park outside the city. From there it's on to Shiretoko for a guided walk through Five Lakes territory, then south through the Mashu and Kussharo lake district to Kushiro, with stops at viewpoints along the way that no train window ever quite captures, finishing with spring canoeing on the marsh.
