Shiraishi Island白石島

Go for one night in Jul–Aug if you want a beach; otherwise skip — the ferry and the single restaurant make a day trip thin.

Shiraishi is a Seto Inland Sea island of about 350 people, part of Kasaoka in Okayama Prefecture. It is a summer island: a public beach, sea kayaking and windsurfing, a free beach campsite and the Shiraishi Odori dance on 14–16 August. Outside July and August most facilities shut and the island is a quiet walk.

  • 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.

Watch out

Safety

Very safe. The real risks are the last ferry, summer heat and swimming without a lifeguard: check the timetable and the sea conditions before you swim.
  • Ferries are limited and the last boat back to Kasaoka leaves in the evening: check the Sanyo Kisen timetable before you commit to a day trip.
  • San-chan's is the only real restaurant; it opens Jul–Aug and may close early on weeknights unless you call ahead.
  • Self-caterers should buy food in Kasaoka — the supermarket is next to the ferry terminal and train station.
  • Most guesthouses take cash; the only ATM is at the post office during business hours.
  • Mobile coverage is fine on major carriers; free Wi-Fi is at the port and some lodgings.
