Aso Caldera & Crater
Rim to crater across an ocean of grass
For walkers and drivers who want to see one of the world's largest calderas from the edge, from the floor and from the lip of the crater itself.
- 1
Aso Shrine and Monzenmachi
Take the JR Hohi Line from Kumamoto to Aso Station, about 90 minutes, and pick up a rental car or taxi there; the shrine is ten minutes east. Arrive around 9:00, before the crater shuttle traffic. The great gate was rebuilt after the earthquake, and the lane in front of it, Monzenmachi, has spring water flowing from spouts every few doors, so bring a bottle to fill.
45 MinutesCost: Free 
2Daikanbo lookout
Drive about 20 minutes north up the caldera wall onto the Milk Road, the rim road named for the dairy pasture it runs through. Daikanbo is the highest point of the northern rim, with a car park and a ten-minute walk to the viewpoint. From here the five central peaks line up like a sleeping figure, and the whole caldera floor of towns and rice fields is at your feet.
1 HourCost: Free
3Kusasenri grasslands
Come back down and take the Panorama Line up the central peaks, about 40 minutes, to Kusasenri by 12:00. It is a flat green meadow inside an old crater, with two ponds and grazing horses, and the smoking Nakadake behind it. Walk the loop around the ponds, then eat in the restaurant at the Aso Volcano Museum opposite, whose exhibits explain what you are about to look into.
1 HourCost: Free- 4
Nakadake crater
A shuttle bus or your own car covers the last stretch to the crater car park; the road is tolled and it closes whenever gas levels or the alert level rise, so check the board at Kusasenri first. When it is open, a short paved walk brings you to the fence above a turquoise lake steaming in a grey bowl, with concrete shelters along the rim. People with asthma are asked not to go up.
1 HourCost: ¥500–1,000 - 5
Komezuka and an onsen
On the way down, stop at Komezuka, a small perfect cone of grass with a dimple in the top, viewed from the roadside; you cannot climb it, but the short path to the viewpoint takes ten minutes. Then finish around 16:00 at one of the day-use hot springs at Uchinomaki near Aso Station, where the bathwater is heated by the mountain you have just been standing on.

Tips
A car is the honest answer for this day: buses from Aso Station reach Kusasenri and the crater, but not Daikanbo, so without one drop the rim and do the central peaks by bus instead.
The grassland loop and the crater rim are exposed with no shade: hat, windproof layer and shoes for gravel; the rim is always several degrees colder than the caldera floor.
Aso is dairy country, so the soft-serve and milk at the Milk Road farms are the snack, and akaushi, the local red beef, is the lunch worth sitting down for.
Daikanbo is a morning shot, with the sun behind you and the peaks lit, and on autumn dawns a sea of cloud fills the caldera below it.
