What is Karasawa Cirque?

The geography term “cirque” means a crescent-shaped or bowl-shaped valley, with steep sides, formed by glacial erosion. Karasawa Cirque is one of the most gorgeous spots in Kamikochi (or even Japan) for Koyo (autumn leaves) viewing, located at an altitude of 2,300m above sea level. The best time to see autumn leaves around the Karasawa area is usually from late September to early October. It is also an important base for climbing to the peaks of Hotaka Mountain.

Planning Your Hike

Hiking Map

Mountains are connected, so you can actually hike from anywhere. But in this blog, we will give directions on how to hike from Kamikochi, which is the easiest and most popular route.

Course Time

The total hiking distance is about 30 km long. This time we had a 2 days, 1 night hiking plan, staying overnight at the Karasawa Hutte.

If you are a slow walker or you happen to start your hike late or you are still new to hiking, I recommend you stay at Yokoo Sanso, instead. Your hiking plan might look something like this.

Day 1: Kamikochi Bus Terminal > Yokoo Sanso (overnight)
Day 2: Yokoo Sanso > Karasawa Cirque > Yokoo Sanso (overnight)
Day 3: Yokoo Sanso > Kamikochi Bus Terminal

Whatever hiking plan you make, ensure that you are able to reach the mountain lodge or campsite at around 2-3PM (or the latest at 4PM).

Restaurants and Toilets

As shown on the map, toilets and restaurants are everywhere along the trail. In Kamikochi you pay to use toilets. There is no change, so it is recommended to prepare some 100-yen coins with you. Also, note that they are bio toilets, so don’t expect a typical Japanese high-tech toilet you see elsewhere.

Mountain huts usually offer lunch menus, snacks and drinks for non-staying hikers. The farther you go, the higher the prices, which is understandable, considering the transportation cost. For example, one can of Coca-Cola sold at Karasawa Hutte costs 400 yen, about 3 times the normal price.

Mountain Huts and Campsites

An advance reservation is required. Showing up on the day without a reservation increases the burden of the operation staff. Also, no matter what the reason is, if you have booked and you can’t make it, please inform the lodge. They may contact the rescue team to search for you because assuming you are lost. However, those who stay in a tent don’t need to reserve beforehand.

Note: Most mountain huts don’t accept credit cards, so please bring enough cash.

*Approx. price is per person including 2 meals. / **Shower only, no soap and shampoo allowed.

For the latest information, please contact each mountain hut directly.

Tokusawa lodge is the most well-equipped one out of the four. They even provide you with free Wi-Fi and basic amenities like in typical hotels. Yokoo Sanso is also a quite comfortable mountain lodge, especially for newbie hikers, because they have a public bath for you to wash out dirt.

Karasawa Hutte and Karasawa-koya are the most popular ones for those going to Karasawa Cirque, owing to its location and superb views. But in comparison, I would say Karasawa Hutte is probably a little more popular than Karasawa-koya. During the ‘Koyo’ season, it is so crowded that you might have to share one futon (bed) with other two strangers. Reservation is available 1 month prior (by phone only).

Summit your trekking itinerary

Anyone going further than the flat area of Kamikochi needs to summit a trekking itinerary. The mailbox is located at the entrance of Kamikochi Information Center, next to the toilets. There are forms for filling provided at the post. But our advice is to download the form online and fill it out beforehand for a smoother process.

Hiking Route

Kamikochi Bus Terminal

Normally, people start hiking at around 06:30 – 08:00. If you start later than that, you’d better speed up or plan to stay at Yokoo Sanso. From the bus terminal to Yokoo Sanso, it is about 10 km long and it takes about 3 hours. This section is mostly a flat area with gentle slopes, making it the perfect warm up before the real hike.

Right after sunrise, Kamikochi bus terminal starts to get crowded with avid alpinists.
The privilege of early visitors is being able to see the Kappa Bridge without flooding tourists.

If you don’t want to sleep on a night bus or wake up at 04:45AM to catch a bus to Kamikochi, staying at one of the hotels in Kamikochi the night before is highly recommended.

From the bus terminal, you can walk on both sides of the Azusa River but if you choose to walk on the right shore (the opposite side of the bus terminal), you have to cross the Myojin Bridge to get back to the trail.

After about an hour, we see the first landmark on this hiking trail, a lodge and restaurant, Myojin-kan. There’s still a long, long way to go, so we walk past without stopping.

The zigzag peaks in the back are Mt. Myojin.

The trail is easy to follow, as we will be walking along the Azusa River more than half of our journey.

Look out to the left, you will see the crystal-clear river from time to time.

The next stop is Tokusawa, which is only about 2 hours from the Kappa Bridge. If you come here around the middle of May until early June, you will see a carpet of little white flowers called “Nirin-so”. It is one of the signs of spring in Kamikochi.

Surrounded by tree shades, this is a tenting area near Tokusawa Lodge.
Walk, walk, walk!
Twin mushrooms!

Yokoo Sanso

From Tokusawa, it takes about 1 hour to Yokoo Sanso mountain hut. After having a short break at Yokoo Sanso, we cross the Yokoo Ohashi Bridge, and this is where the real hike begins. A rocky trail continues for a few minutes before entering the forest path again.

Hondani Bridge

After approximately 1 hour-walk, you’ll arrive at Hondani Bridge, another fabulous spot on this hike. Listening to the sound of the flowing river while eating and watching the clouds moving slowly from side to side. No wonder why just a simple curry bun bought from 7-11 tastes this good! (Though actually I was secretly craving for those sizzling onions and meat on the frying pan from a couple beside me…)

A curry bun bought from 7-11, it actually tastes quite good. You can always trust Japanese convenient store!
Can I join in, too...? (making sad face)

There are plenty of spaces for everyone to have a seat.
Strange-looking but beautiful clouds.

From this point, the trail gets a lot steeper. On the way climbing up, we saw a lady hobbling down with one leg tied to a makeshift splint made from a hiking pole. She was crying without a sound. (You know how bad it is when you cry silently.) Shortly after that, we saw a rescue team passing, assumed that they were rushing to help that poor lady. So, everyone, please be very careful!

A steep climb of mostly rocks
Maples trees are rarely seen in Kamikochi but we still manage to find them!

Another major landmark is this short section of rocky path, where one side is a huge slope of rocks, while the other side is a jaw-dropping beautiful ravine. However, it is a dangerous spot with high risk of falling rocks, so don’t stop here for too long.

A short breathtaking but dangerous path just before reaching S Gare.

S Gare (S Scree)

This little sign tells you that you have now arrived the point called “S Gare”. “Gare” in Japanese means “a scree slope”. Nothing special, it’s just a sign telling you that there is only about 1 hour left to Karasawa Cirque.

A wood sign with “S Gare” written on. It appears out of nowhere in a place without anything catching your eyes, you probably walk pass it without even noticing.

The passing scenery was mind blowing, but the nearer you get to the Karasawa Cirque, the scenery gets even better as you can see more vivid autumn leaves.

Karasawa Cirque

Finally, after about 6 hours of hiking, we have now reached the Karasawa Cirque! The sceneries before our eyes are just a big wow factor! The Hotaka mountain range looks so close to us (although you need another 4 hours hike to reach Mt. Oku-Hotaka, the highest peak of Hotaka Mountain). And look at those colorful tents below! Did someone just drop a pack of m & m’s on the ground?

Nothing is better than eating while appreciating the beauty of natural wonders, so we ordered a ramen (1,000 yen) and a Coca-Cola (400 yen). Their popular menu “Oden” (Fish cake stew) was already sold out, so we missed out! As the best spots on the terrace were already taken, we had no choice but to sit anywhere unoccupied.

Soy sauce based ramen noodles and Coca-Cola.
Various menus include curry rice, beef bowl, cup noodles, beers and even a soft serve!

Too bad that almost shortly after we had arrived, the sky suddenly got cloudy. We  should have taken more photos when the sky was still clear.

This is the best spot where you can clearly see the peaks of Hotaka Mountain and Karasawa Cirque that looks like scooped out ice cream.

The place we stayed for the night is “Karasawa Hutte”, which is only a few steps below the terrace. It is a very well organized and comfortable mountain hut. It consists of 3 separate buildings.

Reception and cafeteria are in the building above.
Souvenirs and some necessities for hiking are available at the shop.
Spacious, clean and warm cafeteria.

We were assigned a room with bunk beds to sleep with other 6 people. The room was clean but if you need a higher level of cleanliness, you can buy a disposable inner sheet to put inside your bedding. I am not sure but from what I see there are rooms where you sleep side by side with other people like any other mountain huts. By the way, the lights-out time is 9:00PM.

My room for this night.

Breakfast and dinner times are divided into 3 rounds, 30 minutes each. You will be informed your round when checking in.

Our dinner (left) and breakfast (right). You can ask for more rice and miso soup.

Note: Paid toilets (100 yen) are available for non-staying guests (free for staying guests). You should expect a long queue in the morning.

The terrace shop opens from 6AM until 5PM.

Highlights of the Trip

After dinner time, we went out for the highlight of the night. The entire tenting area was lit up beautifully, creating a magical scenery.

The lights shining through from inside these colorful tents with the Hotaka Mountains behind is one of the main events that everyone waits to see. It is said that the record for the highest number of tents is as many as 1,400 in just one night! The building standing individually beyond the tents area is another mountain hut, “Karasawa Koya”.

The next morning was quite busy as we woke up early at 5AM, quickly finished our breakfast and hurried to secure a spot to witness “morgenrot”, a fantastic phenomenon when the rising sun casts its reddish rays across the mountain peaks. This term comes from German words, “morgen” (morning) and “rot” (red). The memorable moment lasts only about 5-10 minutes and will not happen unless the conditions are met. So, yes. We were lucky enough!

Nagano prefecture is surrounded by mountains, including the Japanese Alps. There are several places that you can see morgenrot, even from the downtown. Maybe we can write about that for the next blog entry!


Getting to Kamikochi

Another reason why Kamikochi is such a popular hiking destination is that it is very easy to get to, with various bus routes from all major cities.
