A day circuit through two of western Honshu's great contrasting landscapes. Akiyoshidai is Japan's largest karst plateau — 130 to 420 m of open grassland studded with over 40,000 white limestone pinnacles above a 10 km cave system. Hagi, an hour north, is an exquisitely preserved Edo-period castle town on the Sea of Japan — birthplace of five Meiji-era prime ministers and still enclosed within its original street grid. The loop from Yamaguchi fits both in an unhurried day.
