When the snow begins to melt and the Okhotsk sea ice recedes, Shiretoko National Park undergoes a dramatic transformation. For those looking to get up-close-and personal, there is no better way to experience this awakening than through Picchio Shiretoko, a leading eco-tour operator dedicated to sustainable wildlife conservation.
Spring in Shiretoko (late April to early June) is a season of “firsts”: the first bear sightings after hibernation, the first alpine flowers peeking through the soil, and the first songs of migrating birds.

The Shiretoko Five Lakes (Goko) are the crown jewel of the peninsula. In spring, the “Vegetation Protection Period” begins around April 20th. This is a rare window where you can walk the ground trails before the high-intensity “Bear Active Season” (starting May 10th) necessitates more stringent safety measures.
Why Spring? The mountains of the Shiretoko Range are still capped with brilliant white snow, reflecting perfectly in the glass-like surfaces of the five lakes.
The Picchio Advantage: Their expert guides help you spot bear claw marks on trees and identify the tracks of Ezo deer and red foxes that are highly active during this season.
Known as the “Maiden’s Tears,” Furepe Waterfall is a cliffside marvel where water trickles directly into the Sea of Okhotsk. In spring, the frozen starbursts of winter melt into a gentle flow.
Flora & Fauna: The trail to the falls passes through vast grasslands where you’ll likely encounter Ezo deer grazing on the fresh spring shoots. It’s also a prime time for birdwatching as migratory species return to the northern forests.
Even in spring, the wild doesn’t sleep. Picchio’s Wildlife Night Drive is one of Shiretoko’s most popular experiences.
The Experience: From the safety of a guided vehicle, you’ll head into the national park after dark. Using high-powered spotlights, guides help you locate the glowing eyes of Ezo deer and foxes. It’s a mysterious, educational adventure that offers a completely different perspective of the forest than a daytime hike.
What sets Picchio apart is their commitment to coexistence. Picchio began in Karuizawa as a bear conservation group and brought that expertise to Shiretoko. By joining their tours:
You contribute directly to bear conservation and local environmental protection.
You learn the “Shiretoko Rule”—how to enjoy nature without disturbing the delicate balance of Japan’s last true wilderness.
Booking Tip: Spring weather in Shiretoko is unpredictable. Picchio provides free rentals of rubber boots and rain gear, but you should layer up! Even in May, the breeze from the Sea of Okhotsk remains very chilly.
