Northern lights in Shiretoko tonight

Utoro is the main settlement on the western side of Shiretoko Peninsula. The coastline faces north over the Sea of Okhotsk with no significant light source on the horizon. Bortle Class 2. The car park at the cape north of Utoro gives an unobstructed north-facing position above the sea. In winter the drift ice that arrives in January-February extends the dark foreground further. The small amount of illumination from the village is low and directed downward; moving 1-2 km north of the main settlement eliminates it entirely. This is among the darkest accessible coastal positions on Hokkaido.

The Shiretoko Five Lakes area is 12 km from Utoro along the peninsula road. At night the elevated boardwalk gives a platform above the surrounding forest canopy with an unobstructed northern view. Bortle Class 1-2. The lake surfaces reflect aurora when conditions are calm. The peninsula road beyond the Five Lakes is closed in winter (October to May), making the Five Lakes the furthest accessible point from Utoro by car. The absence of any settlement within 15 km in any direction gives conditions comparable to the most remote spots in Hokkaido.

The road to Kamuiwakka Falls continues beyond the Five Lakes in summer, reaching further into the interior of the peninsula. This road is closed October to late May, limiting winter access. When the road is open in early autumn (September to mid-October), positions along it give Bortle Class 1-2 conditions with an open north-facing horizon above the tree line on the coastal ridges. For winter visits, the Five Lakes area (12 km from Utoro) gives the best accessible dark sky on the peninsula. Note the road closure before planning - checking the Shiretoko Nature Centre website is advised.
