Three ways to reach Kumejima Island from Naha: Kumejima Ocean Jet high-speed ship (82 min, ¥7,800), Kumeshosen ferry (3-4 hours, ¥3,450), and RAC flight (30 min, ~¥15,000). Ocean Jet launches May 1, 2026 from Naha Tomari Port.
Kumejima Island is located approximately 100 km west of Okinawa’s main island. Until 2026, the only options were a slow ferry or expensive flight. The launch of Kumejima Ocean Jet on May 1, 2026 introduces a third, game-changing option: a high-speed jetfoil that cuts travel time to just 82 minutes.
Option 1: Kumejima Ocean Jet (High-Speed Ship)
Departing from Naha’s Tomari Port, the jetfoil “Tsumugi” reaches Kumejima’s Kaneshiro Port in approximately 82 minutes. Equipped with hydrofoils, the vessel virtually eliminates wave-induced motion, making for a smooth ride even in rough seas. Adult one-way fare is ¥7,800, with discounts available for families (¥5,000), early booking (¥5,000 for 61-92 days advance), seniors (¥4,000), and island residents (¥5,400). Reservations are made through Google Forms at ko-jet.com. The Motobu route (approximately 60 minutes, ¥6,800) also connects to northern Okinawa, providing convenient access to Churaumi Aquarium and JUNGLIA theme park.
Option 2: Ferry (Kumeshosen)
The traditional route operated by Kumeshosen runs from Naha Tomari Port to Kumejima Kaneshiro Port in 3-4 hours. At approximately ¥3,450 one way, it’s the most budget-friendly option. The ferry can transport vehicles, making it ideal for travelers who need a car on the island. Daily departures are available, though rough seas can cause cancellations during winter months and typhoon season.
Option 3: Flight (RAC)
RAC (Ryukyu Air Commuter) operates daily flights between Naha Airport and Kumejima Airport. Flight time is approximately 30 minutes, making it the fastest option. Standard one-way fares start around ¥15,000, though advance purchase discounts can reduce this. Seat availability is limited, especially during peak travel periods.
Which Option Should You Choose?
For day trips: Kumejima Ocean Jet is the only realistic option, as the ferry takes too long and flights are expensive. For overnight stays on a budget: the ferry offers the best value. For business travelers or those short on time: flights are fastest, but the Ocean Jet offers a compelling middle ground at one-third the price. For families: the Ocean Jet’s family discount (¥5,000) makes it the best overall value when factoring in time savings.
