Standing on the rim of the caldera

Mount Aso is famous for its caldera (a vast hollow left behind by a volcanic eruption), formed by enormous eruptions long ago. Daikanbo is the highest point on the northern side of the ring of mountains that encircles this caldera (known as the outer rim), at 935.9 m above sea level.

It stands about 400 m above the Aso Valley spread out directly below, with the town and farmland of Aso city. Looking out over the towns and rice fields sitting inside the hollow, with the Five Peaks of Aso (the five mountains rising in the middle of Aso) lined up beyond them, you really get a feel for just how big the caldera is.

Named by a writer of the Meiji and Taisho eras

This spot was originally called Tomigahana. In 1922, Tokutomi Soho, a journalist and historian from Kumamoto, gave it the name Daikanbo. It means "the peak with the great view", a name that describes the scenery exactly.

Seas of cloud and starry skies

On early mornings from autumn into winter, you may see an unkai, or "sea of clouds", when the Aso Valley is blanketed in cloud. At night there are few lights nearby, so it is also a popular place for stargazing.

The lookout has souvenir shops and places to eat, plus proper parking.

Getting there

Driving is the easiest way to get here: about 90 minutes from central Kumamoto, about 60 minutes from Kumamoto Airport, and about 30 minutes from JR Aso Station or the Michi-no-Eki Aso roadside station.

There is a bus from JR Aso Station that takes about 40 minutes, but it only runs on Saturdays, Sundays and public holidays. Services are infrequent, so check the timetable before you go.

Tips

If you want to see the sea of clouds, aim for a clear early morning between autumn and winter. It is colder up in the mountains than down on the plains, so bring a jacket.
If you go stargazing, take care driving on the mountain roads at night.
