Ishigaki itineraries: timed island-hopping plans
Five plans built on the operators' timetables, with the boat you take out and the boat you take back. Pick one, then change the stay or the islands in the planner.

Leave after breakfast, be back for a late lunch in Ishigaki.

Use Ohara Port: it is the sheltered crossing and the Yubu Island cart depot is a short bus ride away.

Both are sheltered routes with frequent boats.

Only Anei sails here, on open ocean, and the boat does not run at night.

One sheltered two-island day, one Iriomote day, and a third that can absorb a cancellation.
How these plans are made
Each plan runs the same rules as the island-hopping planner: earliest published boat that works, the longest printed crossing time, 30 minutes between boats at Ishigaki, no backup sailings. The island steps come from the island guides, where every fact links to its source. Times are rebuilt whenever the timetable data changes (last check 3 Nov 2026).
Not sure which island fits? Compare them first. Weather can change everything: which routes cancel first.
