A living earth, emitting volcanic smoke. A mysterious lake emerging beyond the mist. And the memories of the Earth, resting deep within the forest. Surrounding the Kussharo Prince Hotel, you can experience the scenery that reminds us that the Earth is still alive. At Mt. Io, steam continuously rises from the ground, revealing the rugged form that the Ainu people called "the naked mountain." Lake Mashu shows its unique expressions, whether it is shrouded in mist or shining with clear blue. In the forests of Wakin Peninsula, memories born from volcanic activity 30,000 years ago lie in slumber. Why not feel the pulse of the Earth, using Kussharo Prince Hotel as your base?

The season of sea of clouds is coming‼︎☁️ Let me introduce the magnificent panorama spots that fill Lake Kussharo and Lake Mashu (around June to October). ☁️Stay in Teshikagacho and head to the sea of clouds spots☁️ In Teshikagacho, you can see the sea of clouds at Lake Mashu during the early mornings from June to October. The Mashu and Kussharo area has several observation decks where you can overlook the mist gathered in the caldera from above, allowing you to enjoy the sea of clouds from various angles. 【Lake Mashu No. 1 Observation Deck (Lake Mashu Kamuy Terrace) & 3rd Observation Deck】 Lake Mashu maintains relatively low water temperatures throughout the year. When the warm summer temperatures and sunlight warm the air above the lake surface, updrafts are likely to occur. As a result, the area becomes enveloped in mist, creating the "Misty Lake Mashu." It is a rare phenomenon for mist to accumulate as a "sea of clouds" over Lake Mashu. At the 3rd observation deck, if the season and conditions align, you can see the double sea of clouds over the Kussharo caldera. If you're lucky, you might also catch a glimpse of the elusive waterfall mist flowing into Lake Mashu. *Image 1 【Tsubetsu Pass Observatory】*Image 2 The view of the sea of clouds from the 947-meter observation deck is breathtaking! It's the best time to witness the divine sea of clouds at sunrise. The scenery captivates fans. Around July 1st / 3:45 AM, August 1st / 4:15 AM, September 1st / 4:45 AM 【Bihoro Pass Observatory】*Image 3 This is the place to see the vast sea of clouds! As a world-renowned scenic spot, Lake Kussharo is so large that it cannot fit into the viewfinder. It's the best spot to see the big sea of clouds. 【Mokoto Pass Observation Deck】*Image 4 You can see the sea of clouds even if you sleep in a bit! With a higher elevation than Tsubetsu Pass, and after sunrise at Tsubetsu Pass, you can take photos with the light coming from this direction. Depending on the cloud conditions, you can also observe the flow and collision of clouds. 🚨Be fully prepared‼︎ Not only during seasonal changes like spring and autumn, but early mornings can be surprisingly cold. Please dress as warmly as possible. If it gets too hot, you can take off layers, but strong winds may prevent you from staying at the location. Layering your clothing for easy adjustments is recommended. For more details, please check Teshikagacho Navi.

🚨 This is the last year‼︎ Be sure to check it out‼︎ The stamp rally for the "2nd Generation Kushiro Shitsugen Norokko Train" has started on April 24th, marking its final operation this year. 🚂✨ You can collect various designs of the "2nd Generation Kushiro Shitsugen Norokko Train" stamps at six participating post offices!
