The Kumejima Ocean Jet launches May 1, 2026, inaugurating Okinawa’s first jetfoil service. The Boeing 929 hydrofoil “Tsumugi” (230 passengers) will connect Naha (Tomari Wharf) to Kumejima (Kaneshiro Port) in approximately 82 minutes in summer (April–November) and ~101 minutes in winter (December–March) and Naha to Toguchi Port in approximately 60 minutes in summer and ~69 minutes in winter. One-way fare: ¥7,800 (Naha–Kumejima).
What’s Launching
Okinawa’s first-ever jetfoil service begins commercial operation on May 1, 2026. The vessel “Tsumugi,” a refurbished Boeing 929 formerly known as JR Kyushu’s “Beetle,” will serve two routes: Naha–Kumejima (82 min) and Naha–Motobu (60 min). This represents a transformative addition to Okinawa’s inter-island transport network.
Why It Matters
Kumejima has been accessible only by flight (~30 min, expensive) or ferry (~3–4 hours, slow). The KOJ creates a third option that balances speed and affordability, making Kumejima a realistic day-trip destination from Naha for the first time. The Motobu route also offers a traffic-free alternative to reach northern Okinawa attractions like JUNGLIA and Churaumi Aquarium.

Kumejima Ocean Jet is set to launch on May 1, 2026, introducing jetfoil high-speed ferry service between Naha and Kumejima Island. The Boeing 929 jetfoil vessel “Tsumugi,” with a capacity of 230 passengers, will reduce travel time from approximately 3.5 hours (conventional ferry) to just 82 minutes. This launch represents a transformative improvement in accessibility for Kumejima Island.
The service will also operate a secondary route between Naha and Tokuchi Port in Motobu (approximately 60 minutes), providing a new access option for northern Okinawa including Churaumi Aquarium and the Junglia theme park. Fares start at ¥7,800 for adults on the Kumejima route and ¥6,800 on the Motobu route, with discounted rates available for children, seniors, and island residents.
