Early morning offers the best conditions for viewing the mountain's reflection, when winds are typically calm and the water surface is most still. The reflection is particularly dramatic in early summer (June-July) when snow still covers Mount Rishiri's peak. Avoid windy days or afternoons when breezes disturb the water's surface.
The complete circuit along the wooden boardwalk is approximately one kilometer and takes 20 to 30 minutes at a leisurely pace. Photographers and birdwatchers often spend longer, sometimes up to an hour, to capture the scenery and observe wildlife.
No, the pond is closed from early November to late April due to winter conditions. Heavy snow makes the boardwalk inaccessible and potentially dangerous. Plan your visit between late April and early November for the best experience.
A car is not essential but convenient. Local Soya Bus service runs from Oshidomari Port with buses every 2-3 hours during summer (¥310, 5 minutes to Himenuma Iriguchi stop), followed by a 20-minute uphill walk. Organized bus tours, rental cars, or taxis are alternative options. Bringing a rental car on the ferry from Wakkanai is expensive, so consider renting directly on the island.
Admission to Himenuma is completely free. However, visitors should budget for transportation costs to reach Rishiri Island and local bus fares or vehicle rental on the island itself.
