Suo-Oshima周防大島
Go for 1–2 nights by car, or a summer beach day from Iwakuni or Hiroshima; without a car, skip — buses are too infrequent.
Suo-Oshima is a rural Seto Inland Sea island in Yamaguchi, joined to Honshu by the Oshima Bridge at Obatake. It sells itself as the Hawaii of Japan because many early emigrants to Hawaii left from here. Beaches, ridge-top viewpoints, mikan orchards and a small emigration museum are the draw. Getting around without a car is slow, so most visitors come by car for a summer day or one night.

Getting around
A car is the practical way: sights sit on ridge roads and the coast, and buses run infrequently. Cabs exist but are expensive. The island is also a cycling destination, though the hills are real. The bridge connects at Obatake on the Sanyo Main Line.
