Best Seasons to Visit Eastern Hokkaido

Spring: Late Blooms & New Life


Spring comes slowly to Eastern Hokkaido. Unlike mainland Japan, the region stays cold well into April—snowfall in March isn’t uncommon, and patches of snow often linger into early spring. Mornings and evenings remain chilly, so layered clothing is a must.

As the land awakens from its long winter, fresh greenery and wildflowers emerge, bringing a palpable sense of renewal.

Wildlife becomes more active too. If you’re lucky, you might spot red-crowned cranes (tancho) leading their newly hatched chicks through wetland grasses.

Summer: Cool Air & Active Days


Summer in Eastern Hokkaido is refreshingly mild—especially compared to the rest of Japan. While inland areas like Kitami can get warm during the day (above 25°C), coastal regions stay cool and pleasant. Evenings can be brisk, so a light jacket is always good to have.

This short but glorious season offers a wide range of outdoor activities: hiking and trekking, birdwatching, canoeing, horseback riding, fishing, cycling, and scenic cruises. It’s the perfect time to explore without the crowds or humidity common elsewhere in Japan.

Autumn: Crisp Skies & Fiery Leaves


Autumn brings more dramatic weather shifts and increased rainfall, but it also signals the start of some of the region’s best sightseeing. Coastal areas prone to summer fog often clear up, revealing crisp, blue skies and vivid landscapes.

From late September into October, Eastern Hokkaido’s forests burst into brilliant red, orange, and gold. The dry, sunny days typical of Hokkaido autumns make it ideal for trekking, canoeing, or cycling through vibrant scenery that feels entirely different from summer.

Winter: Ice, Wildlife & Crystal Skies


Despite the low temperatures, winter in Eastern Hokkaido often means clear skies and magical light. Snowshoeing, ice fishing, winter canoeing, and drifting ice adventures—whether by cruise, walking tour, or fat bike—let you immerse yourself in a frozen world that feels like a dreamscape. This is also peak season for rare raptors like Steller’s sea eagles and white-tailed eagles, which migrate here to overwinter along the coasts and frozen rivers.

Dress warmly with a thick down jacket, thermal layers, insulated snow boots, gloves, and ideally goggles or a face mask to block cold winds—and you’ll be rewarded with one-of-a-kind experiences.
