Aso

Aso is a city sprawling across a massive volcanic caldera, characterized by rolling grasslands, surrounding mountains, and an active volcanic crater at its center. The landscape combines open pastures with steep volcanic slopes, creating a dramatic terrain shaped entirely by geological forces.

The region appeared in ancient Japanese chronicles and underwent several transformations across centuries before three municipalities merged to form the modern city in 2005. This consolidation reshaped local governance and strengthened regional cooperation.

The Aso Shrine anchors the spiritual life of the area, and locals continue to gather there for seasonal festivals and daily worship despite past challenges. Visitors notice how the shrine grounds feel integrated into everyday community life rather than isolated as a historical monument.

Visitors can reach Aso by train on the JR Kyushu Hohi Main Line or by car using several major routes, with rental vehicles readily available in the region. Plan sufficient time to explore the vast area, as attractions are spread across different parts of the caldera.

The Kusa-Senrigahama grasslands within the caldera offer horseback riding tours across natural pastures surrounded by volcanic rock formations. This rare combination of riding activities within an active volcanic landscape sets the area apart from other destinations.
