Takachihokyo

Takachihokyo is a gorge with steep basalt cliffs rising around 80 meters above the Gokase River, displaying distinctive hexagonal columnar formations. These natural walls were created as lava from Mount Aso cooled and solidified, defining the gorge's overall character.

The gorge was carved out by volcanic activity from Mount Aso thousands of years ago, when molten lava cooled and fractured into geometric columnar shapes. This volcanic origin explains the distinctive geological patterns that remain visible today.

The gorge holds deep spiritual meaning in Japanese mythology as the place where the sun goddess Amaterasu emerged from her cave, returning light to the world. This mythological connection shapes how people relate to the landscape today.

The best way to explore the gorge is by rental boat, which allows close views of the cliffs and the 17-meter Minainotaki waterfall. These boat services operate during the warmer months, so visitors should plan accordingly.

The hexagonal rock patterns form through a natural process where cooling lava splits into regular geometric columns, a phenomenon seen in basalt formations worldwide. Many visitors are struck by this geometric precision, not expecting such order in naturally formed stone.
