"Lake Okotanpe
Visited 2024/09/07
Lake Okotanpe is located in the western part of Chitose City, Hokkaido.
It is a small lake located about 7km northwest of Lake Shikotsu, and is located within the special protection area of Shikotsu-Toya National Park. It is a dammed lake formed by volcanic eruptions from Mt. Eniwa.
It is located 300m higher than Lake Shikotsu, has a circumference of about 5km, and a maximum depth of 20.5m.
It is counted as one of Hokkaido's three most secret lakes, along with Lake Onneto and Lake Shinonome.
From the observation deck, if it is sunny, the lake surface shines a beautiful cobalt blue, but in summer it is covered with vegetation and is quite difficult to see.
In autumn, the autumn leaves reflected on the lake surface are beautiful."

Understanding Okotanpe Lake's 'Secret' Nature
The lake's color is a major draw, famously shifting from a striking cobalt blue on clear, sunny days to more muted tones when overcast. This variability means each visit can offer a different visual spectacle. The reviews highlight how the lake 'changes color with the weather,' making it a dynamic subject for photographers and nature lovers alike.
Visitors should manage expectations regarding unobstructed views. The 'secretive and mysterious' quality means you might not see the entire lake at once, but the glimpses you do get are often breathtaking. The effort to reach it is rewarded by a sense of discovery and a connection with a less-trodden natural wonder.
Navigating Access and Road Conditions
Travelers have noted that the road was closed a little way past the observation deck, limiting full exploration. It's crucial to check for any recent updates on road status before setting out, especially if you are relying on a vehicle. The possibility of walking between Lake Okotanpe and Lake Shikotsu is mentioned, suggesting an adventurous alternative for those prepared for a longer trek.
Given these potential limitations, it's wise to factor in extra time for your visit. If road closures prevent you from reaching certain areas, the observation deck still provides a worthwhile view. The experience of reaching this 'secret' lake is part of the adventure, and being prepared for minor access challenges enhances the overall journey.
