Mount Aso

Yes, Mount Aso is an active volcano in Japan that has regular eruptions and ongoing volcanic unrest. While it is open to tourists, access to the crater is often restricted or temporarily closed due to volcanic activity, gas emissions, or bad weather, so visitors should check the current status before going. The volcano shows continuous signs of unrest, including sulfur dioxide emissions and occasional volcanic tremors. The most recent major eruption of the main crater occurred in October 2021, but smaller events and steam emissions are frequent. The area around the crater is often restricted to prevent injury from poisonous gases or the risk of eruption. Access is sometimes permitted, but visitors should stay informed about current conditions. Due to toxic gases, the area around the crater is not recommended for people with heart or lung conditions, including asthma.

A far cry from the flashing lights of Tokyo and the bustling crowds of Osaka, the volcanic caldera of Aso provides visitors with a fulfilling sense of peace and serenity. Embark on scenic drives, gorgeous hikes, and bathe in volcanic hot springs, all while surrounded by untouched natural beauty.

Mount Aso is a volcano located in Kumamoto Prefecture on Kyushu Island, Japan. It is one of the largest active volcanoes in Japan and is very famous for the caldera formed by a previous eruption. It is registered as a World Geopark.
