Frequently Asked Questions

A. Tokashiki Island is the largest of the Kerama Islands and is known for clear water and beautiful beaches. Sea conditions can feel very different depending on wind direction, so on your arrival day, check the water first and choose the calmest bay for swimming. With the strong sun, a hat and drinking water are essentials.
A. From Naha to Tokashiki, the Ferry Tokashiki takes about 70 minutes and costs 1,690 yen for adults, while the Marine Liner Tokashiki takes about 40 minutes and costs 2,530 yen for adults. On days with higher waves, the high-speed boat can feel rougher, so people who get seasick often find the ferry easier. If you get seasick, getting a good night’s sleep the day before can help.
A. The Tokashiki Village environmental cooperation tax is 100 yen per person for junior-high students and older, and it’s paid together when you purchase your boarding ticket. Having coins helps speed up payment and can shorten lines in busy seasons, so bringing a 100-yen coin is handy. If you get seasick, getting a good night’s sleep the day before can help.
A. The two main beaches are Aharen and Tokashiku, and the safest choice is whichever has calmer sea conditions that day. Aharen has more facilities and suits beginners, while Tokashiku tends to spread out crowds, making it a better fit if you want a quieter time. With the strong sun, a hat and drinking water are essentials.
A. A day trip is possible for beach time, but you’re tied to boat schedules, so focusing on one beach usually leads to a better experience. Taking a shower near the port before your return and using a large towel for privacy while changing can help you avoid waiting for changing rooms. If you get seasick, getting a good night’s sleep the day before can help.
A. There are shuttles and local routes between the port and major beaches, but rentals are convenient if you want to visit multiple beaches. Because there are many hills, bicycles require stamina, and in summer it’s easy to run low on water—planning “shorter transfers, longer beach time” can help the day go smoothly. With the strong sun, a hat and drinking water are essentials.
A. During summer vacation and long weekends, accommodations fill quickly and boat seats also get crowded. For first-timers, securing things in the order of “lodging → boat → rentals” helps you avoid getting stuck. If your main goal is beach time, staying multiple nights gives you flexibility to work around bad weather. If you get seasick, getting a good night’s sleep the day before can help.
A. With strong sun, a rash guard and marine shoes are comfortable to have. Fine sand can damage phones, so a waterproof pouch is useful, and it can feel chilly on the return boat, so packing a light extra layer can help. If you get seasick, getting a good night’s sleep the day before can help.
