Akanko Ainu Kotan | Review by 楊雅雯

Lake Kussharo

Lake Kussharo is Japan's largest caldera lake, stretching approximately 20 kilometers north to south, and the largest freshwater lake that freezes over on its entire surface. Mt. Mokoto, which created Lake Kussharo, is known for its volcanic eruptions that covered the entire Hokkaido region with its ash in ancient times.

For this trip, we drove from Lake Akan to Lake Kussharo. The scenery along the way was very pleasant, with mountains, forests, and lakes coming together to create the natural atmosphere unique to eastern Hokkaido.
Lake Kussharo is Japan's largest caldera lake. Its vast waters are surrounded by mountains and forests, and standing by the shore looking out over the expansive lake really makes you want to slow down.
That's the beauty of Hokkaido. You don't necessarily need any special attractions—just driving and enjoying the scenery along the way is already very soothing.
This Lake Akan → Lake Kussharo route is really worth including in your itinerary!

Lake Mashu

Situated in the eastern part of Hokkaido, u is a caldera lake located within the "Akan-Mashu National Park". Encompassing an area of about 19.6 km² with a circumference of roughly 20 km, the environs of the vast lake have been designated as a special protection area. Due to the steep cliffs surrounding it, direct access to the lake is restricted. However, several observation decks set up around the lake offer panoramic views of its serene surface.

If you're visiting eastern Hokkaido, Lake Mashu is definitely worth adding to your itinerary!
Lake Mashu is a caldera lake located within Akan-Mashu National Park. It is surrounded by steep caldera cliffs, so you can't walk directly down to the lakeshore and can only enjoy the view from the observation decks. The most captivating feature is its clear, deep blue color. When the weather is nice, the sky is reflected on the lake's surface, creating a truly mysterious and peaceful feeling.
We drove here from Lake Akan, and the route was easy, with pleasant scenery along the way. When we arrived at Lake Mashu and looked down from the observation deck, the entire lake was surrounded by mountains and the view was very expansive. Just quietly looking at the lake felt very soothing.
If you're driving around eastern Hokkaido, I highly recommend visiting Lake Akan and Lake Mashu together, taking your time along the way and experiencing Hokkaido's pristine, vast natural scenery.

Lake Akan

Lake Akan is Hokkaido's fifth largest freshwater lake and is known as a habitat for marimo moss balls. Marimo moss balls can be found in freshwater lakes all over the world, but the ones in Lake Akan have international significance due to their beautiful spherical shape with a diameter of more than 15 cm.

The Lake Akan sightseeing cruise is a classic activity when visiting Lake Akan. The boat leisurely circles the lake, offering views of majestic mountains and beautiful scenery along the way. It also stops at Churui Island, where you can visit the Marimo Exhibition and Observation Center and learn about Lake Akan's precious marimo up close. The entire trip takes about 85 minutes, with a comfortable pace that doesn't feel rushed.
Surrounded by Mount Oakan and Mount Meakan, Lake Akan offers captivating volcanic lake scenery and is also an important home of marimo and Ainu culture. After the cruise, take a walk along the lakeshore, soak in the Lake Akan hot springs, and sample the local food. It's a leisurely, relaxing trip where you can enjoy nature, culture, and food all at once!
A sightseeing cruise is well worth taking when you visit Lake Akan. Taking your time to look around and explore is the best way to travel here.
