[2025 Okuwa Attraction] Travel Guide for Atera Valley (Updated May)

Atera Valley refers to almost the entire valley of the Atera River, which originates in the Central Alps. Because it is a rapids river, there are many rocks, but in places where the flow is calm, the river water is crystal clear and shines an emerald green. It is also known as Atera Blue, and it is simply beautiful. There is a narrow, paved forest road, and a campsite upstream. As I happened to stop by this time, I would like to come properly prepared next time. Public vehicles are not allowed to enter during holidays such as Golden Week and summer, but shuttle buses are available.

| Nagano's hidden gem: Atera Valley. Visit Narai-juku in the morning to experience the local culture, and then head to Nagano's hidden gem in the afternoon to enjoy the natural scenery. 👣【Atera Valley】Located in Okuwa Village, Kiso District, Nagano Prefecture, the river here is crystal clear and has a beautiful emerald color, known as "Atera Blue." The riverbanks are lush with vegetation, and the trail along the river is about 6.3 km long. 📖 The reason for the green color of the stream is similar to Jiuzhaigou. The stream contains a large amount of dissolved mineral ions, which cause the optical phenomenon of "Rayleigh scattering," scattering the "shortwave" blue-violet light in sunlight. ✨ Atera River is a branch of the Kiso River system. The further you go into the mountains from the entrance, the more the water appears blue-green, resembling emeralds! Along the way, there are some famous spots, such as Inukaeri Pool, Kuma Pool, and Ushi Pool, each with its own legend about hunting dogs, cows, and bears (reminds me of the various strange hot springs in Ranma ½ ♨️). ♨️ Speaking of hot springs, Atera also has a hot spring. From the entrance, walk 20 minutes to the right to enjoy the hot spring, which is open for day trips! 🚃 From Nagoya, take the JR Chuo Line towards Matsumoto and get off at Nojiri Station, then walk for 20 minutes. From Matsumoto Station, take the Shinonoi Line and get off at Nojiri Station. ⚠️ If you are staying at Atera Onsen, do not follow the route given by Google Maps. Get off at Nojiri Station and walk for 30 minutes. There is also a bus, but the bus service is infrequent.

This was one of the most picturesque spots I was able to visit in Japan back in 2023 My 3 month trip in Japan included car hire and a stay in a Japanese Ryokan and car hire through the Nagano mountains where I saw the most amazing historical post towns (which I will share) This is Atera Valley! 📍Address: Atera Valley 阿寺渓谷 Nojiri, Okuwa, Kiso District, Nagano 399-5504, Japan 🚘 2 hour drive North East of Nagoya City 🚊Chou Line to Nojiri Station (from Nagoya) If you’d like more information on my trip and how I got here and other things to do comment below and I’d be happy to help! #asiatravel #japan #ateravalley #traveljapan #solotravel #scenicspots #picturesque

📍 Atera Valley, Nagano Prefecture 💞Reasons for recommendation This is an emerald green river located deep in the mountains near the border between Nagano and Gifu prefectures🌞 During the summer, there are restrictions on private cars, so you can park your car at a parking lot along the way and take a shuttle bus or a rented bicycle🚵! I chose a bicycle because I wanted to be able to move freely regardless of time and get off at places with great views to see and take photos! ! It's a mountain path, but it's an electric bicycle, so it's easy🎵 Families can enjoy it too! Bicycle rental fee: 1,000 yen per hour (It took about 1.5 hours round trip to the end of the mountains) If you don't take too many photos and take it easy, you can get back in an hour🌞 The deeper you go into the mountains, the deeper the blue becomes, and there are places along the way where you can play in the river (※There are some dangerous places) Please follow the rules and enter in a safe place. I think the best way to get there is by car 🚗 🙆 ※The Okusa Village website has detailed information about Atera Valley When setting it on your navigation system, I recommend setting it to Atera Valley Second Parking Lot 🅿️ ! 4-5 hours from Tokyo 4 hours from Nagoya It's quite deep in the mountains, but why not go and check it out! ! #aug_trip
