Hiking to Mt. Aso’s Nakadake Crater

We finally made it, Totoro!

Roughly a year ago, Mt. Aso’s Nakadate Crater became safe enough to re-open for viewing after the earthquake in 2016 that destroyed the ropeway and made it inaccessible for years. I first visited Mt. Aso in 2017 during Golden Week, but unfortunately there was not a lot I could do besides visit the surrounding parks and zoos. However, after my vacation to Amami Island, I decided I would fly to Kyushu and visit Kagoshima, Kumamoto, and Fukuoka before flying back to Tokyo.

Each day at 8:30am the official Aso Crater website updates listing the restricted areas of the crater. On days where it rains and the fog is heavy, or when the volcanic gases reach a certain level of intensity, entry will be restricted. However if the weather cooperates, usually no zones are restricted and you can see one of the world’s largest calderas! At one time there was a lake in the crater, but unfortunately now it has dried up. Scientists predict it may reform in the future, however. If you look at old pictures, the color of the blue water looks similar to an onsen with an extremely high temperature.

Here is some footage that I caught on my GoPro of Mt. Aso’s Nakadate Crater:

Getting to Mt. Aso’s Nakadate Crater

From Kumamoto Station, the trip to Mt. Aso take about 2.5 hours by train and bus and costs around 3000-3500 yen one way. You can also rent a car and drive here because the area before the crater has a parking lot. Getting to the crater is a bit of the gamble because there is a slight chance that the gases could change and make some areas restricted as you’re traveling there, but I like to take calculated risks. I thought the trip was worth it because I got to see an extremely rare and beautiful area of Japan. I rode the Hohi Line to Aso Station and then stopped for vegetable udon on the station. It was a hearty and delicious meal.

From the station there are two buses that will take you up to the crater. On your way up you will pass many fields filled with roaming cows and see how beautifully green the mountain is. The first bus will stop at a gift shop where you can buy some interesting souvenirs. My favorite were the oppai sake cups and the Kumamon ice cream, but the rocks from the crater were pretty neat too. You can choose to walk to the crater from here which takes around 30 mins, or take another bus which is just a short 10-15 minute ride. Seeing the Kumamon-themed bus was definitely a perk of using public transport.

On average, viewing the crater of Mt. Aso takes roughly 30-45 mins depending on how many photos you wish to take. There are 5 different zones that you can walk around and see it the crater emitting volcanic gases from. Entry into Zone A is always prohibited, but entering the other 4 zones (B1-D) will give you some amazing views. The experience was extraordinary and very memorable to me. I am happy that I made it all the way up here this time because I crossed another item off of my Japan bucket list!

Other Activities in Aso

Getting to Mt. Aso’s crater and back takes almost a full day, but there are other activities around the mountain that you can do if you’re interested. I took a bath at Aso Bochu Onsen while I was waiting for my train back to Kumamoto which felt amazing after all the distance I traveled to reach the crater. There is also Aso Cuddly Dominion for those who enjoy seeing bears. I visited during 2017 and unfortunately don’t have many good pictures but I had a fun time. I also passed by a horseback riding farm on my way up to the crater. If I would have had more time I would have definitely stopped by!

Thank you for reading about my expedition to Mt. Aso. The article series is officially halfway done! In my next article I will be talking about some activities that I did in Kagoshima. Please look forward to it!
