About the Aso area
The Aso area is home to the world’s biggest inhabited volcanic caldera, known as Mount Aso or 阿蘇山. It’s also Japan’s largest grassland area and home to some gorgeous scenery. Nakadake, the active volcano at the center of Mount Aso is rare; not only is it one of Japan’s most active volcanos but also because when conditions are safe you can go right up to the edge of the crater and look inside.

Getting to & getting around Aso
The Aso region covers an area of roughly 350 square kilometers, as it’s a very rural area public transport is limited. There is so much to see that using public transport you could easily spend several days looking around, however if time is an issue we reccomend either renting a car or taking a private tour.
Aso Volcano Current Status
Level 1 - since April 2022 This is the volcano's safest level. However, currently it is not possible to look inside the crater as the volcanic gas warning system needs repairing and there is a delay in getting the parts. You can of course still see the crater from a short distance and enjoy the Aso area. Click on the title to check if the current status has changed.
