What Is a Dry Dock (Dock Inspection)?
Every ferry in Japan undergoes mandatory annual dry dock (dock inspection) lasting 1–3 weeks. During this period, some routes suspend service or operate with substitute vessels. This guide lists the 2026 dry dock schedule for all Okinawa ferry routes.
Japanese law requires all passenger vessels to undergo periodic inspections in dry dock. This typically means 1–3 weeks per year when a route operates with reduced service or is temporarily suspended. Planning around these periods is essential for island-hopping itineraries.

How to Check & Prepare
Dock schedules are announced 1–2 months in advance on each operator’s website. During dock periods: book accommodation with flexible cancellation, have a backup plan (alternative route or flight), and confirm the schedule directly with the operator before purchasing tickets.
