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.

Watch out
Safety
- 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.
