Lunch break before Akiyoshidō Cave
If you drive in from the Yamaguchi City side in the morning, have a meal and use the toilets at Mitō before heading to Akiyoshidō Cave. It makes the arrival easier.
Michi-no-Eki Mitō → Akiyoshidō Cave. Allow roughly 20 minutes by car.
Eating here is especially useful when the sightseeing area is crowded.
