I was very lucky. This time when I went to Aso, I happened to encounter the crater opening, so I could check in the volcano up close.
We made an appointment for Aso Boy at the manual window three days in advance, but failed to make an appointment, so we took the ordinary JR to Aso. So if you want to take a special train, it is best to make an appointment online in advance.
Aso Volcano is free, but the transportation cost is not cheap. Excluding the cost of going to and from Aso Station, it costs 730 one way and 1460 round trip from Aso Station to Aso Mountain. There are 5 stations on this line. Generally, Kusa Chisato will come down to take a look. It is recommended to buy a pass for 1500 yen. From Aso Mountain to the crater, the one-way cost is 600 yen, and the pass cannot be used. So it costs 2660 yen for a round trip.
In addition, you must pay attention to the time. We went to Kamishiromi Kumanoza Shrine first. When we arrived in Aso, there was only the last bus to Aso Mountain, so we didn’t get off Kusa Chisato. It was so beautiful to see Kusa Chisato on the bus. Don’t miss it. I’m really sorry.
The last bus from Aso Station to Mt. Aso is at 14:55, and the last bus to the crater is at 15:30. The last bus to the crater is at 15:45.
In addition, if you get on the bus from Kusa Senri and take the last bus back to Aso Station, you must leave time for the return JR. because you may not be able to squeeze into the shuttle bus.
The scenery is amazing, it is worth a visit, and if you have enough time, you can also take a helicopter.
