Tsuken-jima is a flat 1.88 km² farming island off Uruma that you reach in 15 to 30 minutes by boat from Heshikiya port, and its carrot fields give it the nickname Carrot Island. About 380 people live in the village by the port.

Tsuken lies about 5 km south-east of the Katsuren peninsula, off the mouth of Nakagusuku Bay. The island is low and ringed by reef, and its soil suits root vegetables so well that about a fifth of Okinawa's carrots come from here. Before the war Tsuken was known for its daikon. A carrot-shaped observation tower near Tumai beach looks over the fields and across to the main island.
The village sits around the fishing port on the south side, and the beaches spread around the rest of the shore. Tumai beach has about 800 m of white sand on the west coast and sits about ten minutes on foot from the port. Yajiri beach on the north side faces the small rock of Afu. Tradition says the cave of Shinugu Gama, which opens onto a sandy beach, is where Akainko was born, and Okinawans remember him as the first maker of the sanshin. The spring at Hotugaa got its name from a dove that led villagers to water in a drought.
The Battle of Okinawa reached Tsuken in 1945, and islanders were moved to Haebaru on the main island and could not return until 1949. Okinawa's first lighthouse went up here in 1896, and its brick base survived the war on the southern cliffs, where the view runs south to Kudaka. About 2 km of the west coast remains a US military training area.
Getting there
Kamiya Kanko runs five boats a day from Heshikiya port on the Katsuren peninsula: the high-speed New Kugani takes about 15 minutes on the first and last runs, and the car ferry Kugani takes about 30 minutes in between. Passenger tickets are sold on the day at the Heshikiya terminal and cannot be booked; cars need a phone reservation.
Getting around
Most people walk or bring a bike, since the island is flat and about 7 km around. From 21 July 2026 to 31 March 2027 Uruma City is running a paid electric-car service on the island as a trial, at ¥300 a section for adults.
Riding on Tsuken-jima
Tsuken is flat, topping out at 39 m, and its farm roads wind between carrot fields that cover about a third of the island. Bicycles ride the ferry for ¥200 each way (¥400 return) on Kamiya Kanko's May 2025 fare table, and the company says bikes need no reservation in principle and asks riders to phone ahead because space depends on the day's cargo. About 2 km of the west coast is a US military training area.
December to March
Kamiya Kanko warns that weather can change or cancel sailings, and it posts each morning on its website which runs will go and which boat takes them. The north-east monsoon blows from December to March, and sea temperatures stay around 21–23 °C.
Worth knowing
- Buy your ferry ticket at the Heshikiya terminal and be on board five minutes before departure; Kamiya Kanko sails on time.
- Parking around the Heshikiya terminal is free and shared with the fishing port, and the ferry company warns it can take a while to find a space.
