Book accommodation early — Kumejima hotels fill up during GW. Popular activities like Hatenohama tours also sell out. See our Hatenohama Guide for planning details. The KOJ makes a day trip feasible if overnight stays are unavailable.
Golden Week (April 29 – May 6) is one of Japan’s busiest travel periods, with millions of people taking advantage of the consecutive holidays. For the 2026 Golden Week, Kumejima Ocean Jet offers a unique opportunity to visit Kumejima Island via the newly launched jetfoil service. The 82-minute journey from Naha makes it possible to enjoy a day trip or short getaway to this beautiful island.
Booking early is strongly recommended, as seats fill up quickly during Golden Week. The Google Forms reservation system opens several weeks before the holiday period. If your preferred dates are fully booked, consider traveling on the first or last day of Golden Week when demand is slightly lower. Accommodation on Kumejima also books up fast during this period, so securing your hotel reservation before booking ferry tickets is advisable.
Kumejima Island during Golden Week offers a perfect blend of beach activities, cultural experiences, and natural beauty. The island’s famous Hatenohama sandbar tours operate daily during this period, weather permitting.
