Walking through the Aso Caldera, Historical Walk along the “Bungo Kaido” – A Balanced Look

Imagine walking along a stone-paved route that’s been used for over 400 years, threading through one of the world’s largest calderas with an active volcano looming nearby. This tour offers that experience, starting from Futae Pass with sweeping views of Mt. Aso and the caldera itself. For about $198.83 per person, you spend roughly four hours exploring the natural and cultural landscape of Aso, with pick-up options and small group settings that make the experience intimate and engaging.
What we love about this tour is how it balances geological wonder and local history, all narrated by guides who truly understand the area’s stories. The walk down the historic Bungo Kaido, a route with roots stretching back over four centuries, is a highlight—serene, scenic, and steeped in stories of old Japan. Plus, the chance to enjoy tea with yogurt and sweets crafted from local grasslands adds a tasty, authentic touch.
On the flip side, a consideration is that the tour requires moderate physical fitness—the walk involves some uneven stone paths and a descent from the outer rim of the caldera.

Exploring the Aso Caldera and the Historic Bungo Kaido

The Aso Caldera is a natural marvel, recognized as one of the largest volcanic calderas in the world. From the start at Futae Pass, you’ll be greeted with a spectacular view of Mt. Aso, the still-active volcano that shapes this landscape.

As you step onto the caldera itself, the landscape unfurls in all its grandeur, giving you a sense of the scale and the powerful forces that created it.
