On the edge of a caldera – Northern Mountain Restaurant and Daikanbo Lookout

5 November 2024

Driving along the Aso Skyline Highway is a “must do” on a road trip in Kyushu. It is a 45 kilometer route that winds along the mountain ridge of the Aso Outer Mountain Ring. Renowned for its stunning panoramic views, this scenic route provides many opportunities to experience the natural beauty of the region. The road is actually on the northern edge of the Aso Caldera.

A caldera is a large depression formed when a volcano erupts and collapses. In the case of Aso Caldera, this massive eruption occurred 90,000 years ago and formed the many unique natural features and landscape in Kyushu. We had seen them at Nabegataki Falls and also Kikuchi Gorge in the morning.

Aso's caldera stretches 25 kilometers north to south and 18 kilometers east to west which is almost the world’s largest caldera. In the center of the caldera, there are five volcanic peaks where they are referred to collectively as Mount Aso (阿蘇山). One of them, Mount Nakadake, is still spewing volcanic gases but yet accessible to visitors.

We drove on the Aso Skyline Road (Highway 45) from Kikuchi Gorge towards Aso city where we planned to stay for the night. There are many breathtaking vistas of the Aso caldera and the majestic mountains that define the landscape.

There were a number of observation spots along the way. We stopped at the Nishiyunoura Scenic Overlook where we planned to have lunch in the Kitayama or North Mountain Restaurant located there.

Nishiyunoura Scenic Overlook

We arrived at the Nishiyunoura Scenic Overlook and went to the North Mountain Restaurant located there. It was already past lunch time at 2 PM and even then, there were people waiting for seats. This restaurant is popular with bikers. We saw many of them in their smart leather outfits waiting for seats as well. We wrote our names on the waitlist and went to enjoy the views from the lookout point.

We could see the checkerboard patterns of the fields and Aso City below. In the horizon, we saw the 5 mountain peaks that formed a silhouette of a person lying down. A signboard showed the names of the five peaks.

Lunch at the North Mountain Restaurant

After 30 minutes of enjoying the views and braving the strong winds at the caldera’s edge, we were seated inside.

Menu in Japanese that we used Google Translate to decipher.

The North Mountain Restaurant serves the Akaushi beef from the rare Japanese brown cattle breed that is raised solely in the Aso region. The menu outside the restaurant was in Japanese. A friendly solo woman traveller who understood Japanese saw us using Google Translate on our phone and helped us with the menu. The menu includes pork cutlet with curry rice, horse sashimi, beef steak and hamburgers.

The restaurant’s famous Akaushi rice bowls came in three sizes S, M and L. The only difference is the amount of rice. My wife ordered the small beef rice bowl that came with soup, tofu, pickles and salad.

A highly recommended and popular item is the double red beef bowl called Super Baikuudon (bike bowl) for 2800 yen. This is probably targeted at bikers who have a big appetite. I ordered the Baikuudon, planning to share some of the beef with my wife.

Look at the red and juicy slices of beef.

Although it is slightly tougher than the typical wagyu beef, the Akaushi beef with the special sauce was delicious.

After lunch, we continued along the Aso Skyline eastwards. This road is also nicknamed as the Milk Road. This road was serving as a route for transporting milk from the dairy farms in the Aso valley. We saw many farms along the scenic drive.

Although there are numerous scenic places to stop, we went directly to Daikanbo since it offered the best views and is Aso's most famous lookout point.

Daikanbo Lookout Point

Daikanbo (大観峰) is a natural observatory located on the highest peak on the northern rim of Mount Aso’s caldera. Daikanbo, which means large observatory, is named for its panoramic views of the Aso caldera, the five central peaks of Mount Aso, Oita’s Kuju Mountain range and the rolling grasslands inside the caldera. Entry to the lookout point is free and the best views were only a short walk from the free car park.

At Daikanbo, which is 936 meters above sea level, we could see the best views of ‘Nehanzo’, the sleeping Buddha silhouette formed by the five Aso central mountains of Mt. Neko, Mt. Takadake, Mt. Nakadake, Mt. Eboshi, and Mt. Kishima. We could see clouds of gas emitting from the active Mount Nakadake.

The sun rays through the clouds on this day was truly beautiful.

Autumn grass blowing in the wind.

The wind at the edge of the caldera was quite strong and Daikanbo is a good spot for paragliding.

It was nice to watch the paraglider sailing over us.

The setting sun would paint the autumn grasslands orange but we could not stay to watch the sunset.

Daikanbo is also a good place to watch the sunset. We did not stay for the sunset as we had to arrive at our hotel before 6 PM, in time for dinner.

From Daikanbo, we headed down the mountain road into the caldera towards Aso City. We would be staying at Minshuku Asogen for one night before heading up to see the 5 volcanoes within Mount Aso up close.

Our stay at Minshuku Asogen in Mount Aso and viewing the One Piece Statue of Usopp

5 and 6 November 2024

I told my family that we would be staying overnight in a hotel inside a volcano’s caldera. Their first reaction was “Huh, is it safe?”

Yes but…. anything could happen. Volcanoes are unpredictable.

Aso Caldera was formed 90,000 years ago in a massive volcanic eruption. The super eruption released so much magma and with such force that the land beneath caved in, creating a giant basin or crater in the land.

The size of the caldera measures 25 kilometers north to south and 18 kilometers east to west, almost half the size of Singapore. Aso City is located on the flat plain on the northern part of the caldera, together with 5 other volcanic mountain peaks in the center. One of them, Mount Nakadake, is still active today.

We chose to stay one night at a hotel within the Aso caldera so that we could explore the area around Mount Nakadake the next morning.

We had seen Aso City from above at Daikanbo, a popular lookout point on the northern edge of the caldera. From there, we drove down the mountain road to Aso City center.

One Piece Statue of Usopp in Aso City

We made a stop at the Aso JR Station. Our aim was to view the One Piece Statue located outside the Aso train station.

On April 14, 2016, Eiichiro Oda, a manga artist and creator of the series One Piece, donated ¥800,000,000 to help reconstruct his home city of Kumamoto after it was struck by two earthquakes. He also wrote supportive messages, and drew art for local products. In 2018, Kumamoto Prefecture awarded Mr. Oda the People’s Honor Award. After rebuilding Kumamoto, the governor Ikuo Kabashima announced that they would build statues of the Straw Hat Pirates to thank Eiichiro Oda for his help.

The Luffy Statue was installed at the Kumamoto Prefectural Promenade to symbolize Kumamoto’s post-disaster recovery. Subsequently, additional statues of the One Piece Pirates were installed all over Kumamoto Prefecture, including Usopp in front of Aso Station.

At the site of each statue, there are collectable figures for sale. These are sold on a first come first serve basis. Most of the statues of popular characters were already sold out but we managed to buy the statue of Usopp at the Michi-no-eki Aso Information Service Center. 

Information on the Kumamoto Revival Project and locations of the statues.

The information center also serves as a grocery and souvenir store. I checked with the staff about the conditions at Mount Nakadake for the next day. If the conditions are right, visitors could drive up a toll road to view the crater of the still active volcano. I received not so good news that it would likely be closed since the wind was forecasted to be blowing from the West.

The lady also provided information about the One Piece Revival project and locations of all the other One Piece Statues in Kumamoto, where to buy the figurines, and the opening hours of the stores.

We bought the Usopp One Piece figurine at the Aso Information Service Center.

Did a brief stop at the JY station to watch this train rolled in.

From there, we topped up the petrol tank in our car before checking into Minshuku Asogen.

Minshuku Asogen is a two-storey guesthouse located on the outskirt of Aso City. There are ample parking spaces in front. The only downside of the car park is that the ground is unpaved and had small pebbles. So we had to lift our suitcases a short distance to the front door which was not a big problem for us. The lobby is spacious and decked in wood provides a warm and homey feel. 

We were assigned a spacious and clean Japanese style room on the second floor. The friendly woman staff that checked us in was quite strong and helped carry one of the suitcases to our room.

The room has a tea set, refrigerator, small flat screen TV, air conditioning and heating. There is a toilet with basin in our room but no baths. We went to shower and bath at the private bath house located in a separate building across the main accommodation building. 

There are 4 private family baths that are free to use between 16:00-22:30 at night and 6:30-9:00 in the morning. Just go to the reception to retrieve the keys and then lock the bathroom when we used it. The layout and fitting inside are all the same.

The water in the hot tub is not natural spring water. Instead Asogen uses normal water with added baking soda electrolytic cleaning solution. The artificial sodium bicarbonate springs is supposed to soften the surface of the skin and turns oils and secretions on the skin into an emulsion, washing them away, leaving skin feeling clean and smooth.

Compared to a ryokan, a minshuku is cheaper but more basic in terms of comfort and service provided. I had booked a stay with dinner and breakfast as I read that the multi-course dinner at Asogen is quite generous and good. Meals are made using ingredients grown in the rich natural environment of Aso.

Dinner was served in a private room on the ground floor. Drinks were not included. We ordered some soft drinks to go with our dinner.

Chawanmushi dish. A savory Japanese egg custard dish steamed in a cup.

We had the chance to taste the horse meat sashimi again. Horse meat sashimi is a specialty of Kumamoto and is typically served in Aso’s guesthouses and restaurants. The high quality meat served at Asogen had a good balance of lean meat and marbled meat.

Horse sashimi served at Asogen with garlic and dipping.

The main course is a yakiniku course with Kumamoto Prefecture's world-renowned premium Wao branded A5 grade wagyu beef and Higo beef. The beef came from cattle bred with pure water and air and has a melt-in-the-mouth texture. The portion of wagyu beef for our yakinuku was so generous considering the fine marbling and high quality of the meat. The dipping sauce for the yakiniku is Asogen's own special secret sauce.

Grilling our beef on the charcoal fire. Less than 30 seconds on each side to get a melt-in-your mouth grilled beef.

Rice dish with miso soup, vegetable tempura and pickles are homemade by the proprietress.

Unlike a ryokan where the beddings were prepared for us by the staff, we had to retrieve the futons and beddings from a cupboard inside our room and lay them out on the tatami mats ourselves. The task was not difficult.

There was a small flat screen TV with HDMI port that I hooked up my Android TV box to. The Wi-Fi was fast enough for me to stream live football at 5 AM in the morning.

Watching my favourite team play.

We had booked our breakfast time during check-in. At the appointed time, we showed up at the private dining room and our Japanese style breakfast was all laid out for us. It was a typical Japanese style breakfast with freshly cooked white rice made with sun-dried rice, miso soup and side dishes. The side dishes included the yucky, sticky natto that I did not touch, grilled mackerel, egg mayo with tomato and various types of pickles.

We were provided with a raw egg from free ranging chickens that we could cook ourselves on a table-top stove with bacon and sausage in it.Having fun cooking our egg.

Overall, it was an excellent, value for money stay in Minshuku Asogen. For the price we paid, we got a decent room, good service and a really nice multi-course dinner with generous portions of high grade wagyu beef for our yakiniku.

Visiting Mount Aso – Komezuka, active volcano Mount Nakadake and Kusasenri grassland

8 November 2024

We stayed overnight at Minshuku Asogen located in Aso City so that we could visit Mount Aso and its volcanos in the morning. From Minshuku Asogen, we followed the directions given by Google Maps but could not find the inconspicuous turn-off from Highway 57. After a few unsuccessful attempts, going up and down Highway 57, we decided to ditch the route Google Maps recommended and just follow the road signs to Mount Aso instead.

The road signs pointed us to use Prefectural Road 111 that will lead us all the way to the Aso Volcano Museum and Mount Nakadake.

Highway 111, also known as the Aso Panorama Drive, is a scenic drive up the mountain. We drove slowly, looking out for Komezuka, an 80 meters high volcanic cone that is supposed to be quite photogenic. 

We saw a small hill that looked like a overturned bowl of rice with a small depression on its top, located on the rigth side of the highway. We found a safe place to park our car by the side of the road (Google Maps location here).

With Komezuka in the background.

Komezuka is said to have been formed by an eruption about 3,300 years ago. The depression at its top is actually the crater of the volcano.

We stopped once more at a spot further down highway 111 to view Yomezuka from another angle. In autumn, the Japanese pampa grass swaying in the wind made the view more scenic.

The mountains in the background is the rim of the Aso caldera. Japanese pampa grass is in the foreground during autumn.

We parked our car at a free car park (location here) next to an observation deck. This lookout point offers a good view of Mount Aso’s mountains, the grassland called Kusasenrigahama and the large parking area outside the Aso Volcano Museum.

The wind was quite strong here. Our hiking jackets kept us warm and comfortable while we enjoyed the views.

We saw Nakadake, the active volcano in Mount Aso, spewing white clouds of steam and gas. I took some time-lapse videos of the gases and steam emitting from Nakadake and the clouds above it.

Kusasenrigahama (“Grassland of a Thousand Miles” ) is the dormant floor of an ancient volcanic crater. It is quite vast and ponds could be seen on it.  Behind the grassland is Mount Eboshidake.

There is another observation deck to our left but we did not go there. Instead, we took a short walk down to the Aso Volcano Museum.

Trail leading down from the observation deck to the Aso Volcano Museum. 

The best way to enjoy a visit to Mount Aso is to drive up to the edge of Mount Nakadake and view the crater within. This could be done of the eruption alert level is low. I was checking the website https://www.aso-volcano.jp on a regular basis on this day.

The good news was that the alert level was low, so the toll road up to Nakadake crater was opened. The bad news was that the wind direction was blowing gases in the wrong direction. Most areas were restricted due to gas emissions. Visitors could only view the crater from the visitor center, not from the edge of the crater. Hence, we decided not to go up to the crater.

Our Plan B, if we could not drive up to the Nakadake crater, was to do a 2 hour loop hike up and down Eboshidake. The weather was not looking good and we could see storm clouds swirling on top of Mount Eboshidake. So Plan B was aborted too.

Plan C was to chill at a cafe and take a walk around Kusasenrigahama. We had coffee at the Kusasenri Coffee Roastery. The drip coffee was very good. We also bought some Kumamoto souvenirs from the shop next to the cafe.

We crossed the road and entered into the Kusasenrigahama grassland. The weather seems to be slightly better compared to when we arrived.

We hiked up a small knoll on our left to get a closer view of Nakadake volcano. Although the eruption alert level was 1, there were quite a lot of gases being emitted from the crater.

After we had enough of Nakedake, we went to see the horses at Kusasenrigahama. Visitors to Mount Aso could ride horses from the operators located on the vast grassland. Business is not too bad. We saw many visitors riding horses around the grassy plains.

We spend some time to take photos of the horses. They are bigger than I expected and so well groomed.

It was about noon time when we left Mount Aso. The plan for the rest of the day was to have lunch and visit a few places in southern part of Mount Aso called Minami-aso.
