🐦 Through Caldera Paddy Fields and Scenic Mountain Views: A 22km Ptarmigan Loop 🐦
Aso City in Kumamoto Prefecture, set within one of the world’s largest volcanic calderas, rests peacefully beneath the majestic peaks of the Aso-Kuju National Park. Blessed with fertile volcanic soil and crystal-clear spring water, the basin features vast emerald rice fields framed by the towering outer rim. This rich agricultural tradition has sustained local communities for centuries alongside deep-rooted spiritual beliefs tied to the volcanic mountains.
