Shiretoko Peninsula, a UNESCO World Heritage site, is the stronghold of Japan's Ezo brown bear, the country's largest land predator, with roadside, boat, and guided river treks delivering sightings from May through October. Salmon season in September concentrates bears along Shiretoko Goko lakes and river mouths, while spring treks reveal mothers with cubs on snow-dusted slopes as they emerge from dens. Commercial day trips from Utoro and Rausu combine coastal boat watches with forest trekking on one of Asia's most accessible brown bear circuits.
