Rules in force · 5
- East Asia ↗Every border in East Asia is a full international border, Hong Kong and Macau included: an entry permission for one never covers the next.
- East Asia ↗Ferries between Korea, Japan and China cancel in rough seas and typhoons; keep a flight or a spare day behind every sea leg.
- Japan ↗IC cards (ICOCA/Suica) are topped up with cash at station machines.
- Japan ↗Smoking while walking is banned in most city centres; use designated areas.
- Japan ↗Shinkansen bags 160–250 cm (L+W+H) need a seat reserved with the oversized-baggage area.
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.
