1 operator run this water, from 30 min. Kohama has an airport 26 km from the quay, so this is a crossing you can make one way and fly the other.
One row per operator and speed. Where a service is sold as fast and its average does not clear 45 km/h, the word appears in quotation marks — the boat is fast craft, the crossing is not.
If this crossing does not suit, these quays also reach Kohama without a change. It is the question a single-route page cannot answer about itself and an atlas can.

Our records for the Ishigaki–Kohama crossing were read on 11 August 2026 and describe the network as it ran that week. We hold no month-by-month variation, so this page cannot tell you whether a crossing runs in February.
If you are travelling well outside August 2026, confirm with the operator before you plan around it.
No fares. Not for this crossing, not for any crossing, not for any mode.
No departure times. A weekly rate is a lower bound on how often the crossing runs — never a clock.
