Myoko Kogen in Summer: Hidden Trails, Onsen & Activities for a Perfect Green-Season Stay

When most people think of Myoko Kogen, they think of deep powder and skiing. But the "Green Season" (summer) is actually the locals' favorite time of year.

While Tokyo and Osaka are hot and humid, Myoko remains cool and breezy. It is quiet, uncrowded, and full of nature. Whether you want to hike a volcano or just sit by a lake with a coffee, this is the perfect place to escape the city heat.

Here is how to make the most of Myoko’s summer.

1. Explore the Hidden Trails

Myoko Kogen offers some of the best hiking in the Nagano–Niigata region. You don't need to be an expert climber; many trails are flat and easy for families.

• Imori Pond Nature Trail: A very easy, flat walk. On a clear day, you can see the reflection of Mount Myoko on the water. It is perfect for morning photography.

• Naena Waterfall: Known as one of Japan’s "100 Best Waterfalls." The walk to the falls takes about 15 minutes through the forest and is very refreshing in July and August.

• Sasagamine Plateau: A high-altitude area perfect for picnics and cycling. The air here is noticeably cooler than in the main village.

• Mount Myoko Hiking Route: For experienced hikers only. This is a challenging climb with rewarding views of the volcanic landscape at the summit.

2. Lake Nojiri Activities

You don't have to stay in the mountains all day.

Just 11 minutes away by car, Lake Nojiri offers a completely different vibe. You can rent a canoe, go pedal boating, or try Stand Up Paddleboarding (SUP). The lakeside is lined with small cafes and restaurants where you can eat lunch with a view of the water.

Local Tip: Try the grilled corn sold at the shops near Naena Waterfall or Lake Nojiri. It is a local summer specialty.

3. Summer Onsen (Hot Springs)

Hot springs are not just for winter. After a day of walking or cycling, an outdoor bath (Rotenburo) is incredibly relaxing.

• Akakura Onsen: famous for its "skin-beautifying" water.

• Ikenotaira Onsen: features black, mineral-rich mud baths.

• Myoko Onsen: quiet, public baths surrounded by deep green forests.

4. Where to Stay

Summer is the best time to rent a private chalet. Without the need for ski drying rooms or shuttle buses, you can enjoy a more relaxed style of travel.

Places like Kasa Kita offer full privacy and spacious living rooms, making them perfect for families or groups who want to BBQ and relax on a deck. It is a peaceful retreat that feels like a true home away from home.

Final Thoughts

Myoko Kogen is a year-round destination. The Green Season offers cool air, empty trails, and a slow pace that you cannot find in the city. If you want a break from the heat and crowds, pack your walking shoes and head to the mountains.
