Naha-Departure Tokashiki Island Day Trip | Swimming and Snorkeling in Kerama Blue Waters

A Day Trip from Naha to Tokashiki Island in the Kerama Islands

This tour takes you by boat from Naha to Tokashiki Island, the largest island in the Kerama Islands, where you can enjoy swimming and snorkeling before returning the same day. The total duration ranges from 7 hours 30 minutes to 9 hours 40 minutes, depending on the boat and plan you choose.

Once you arrive on the island, a dedicated shuttle vehicle takes you to the beach, so there's no need to worry about transportation even though the island has no public bus routes. This is a group tour with local meeting points, available in English, Japanese, Korean, and Chinese (Mandarin).

The tour has a rating of 4.3 (based on 298 reviews). Lunch is included in every plan.

Aharen Beach | 800 Meters of White Sand and a Calm Bay

Aharen Beach is one of Tokashiki Island's signature beaches, featuring about 800 meters of continuous white sand. Because it sits within a bay, the waves are relatively calm, making it a comfortable spot for young children to enjoy the shallows.

The water here is remarkably clear, and you can spot coral within walking distance from the beach. Right next door is an observation deck, where the Kerama Blue waters seen from above are considered one of the beach's main highlights.

How long you can stay depends on the boat you choose: a round trip by high-speed boat allows for about 6.5 hours on the beach, while a round trip by ferry gives you about 3.5 hours.

Tokashiku Beach | A Hidden Gem Known for Sea Turtles and Shallow Waters

Tokashiku Beach is a shallow-water beach known for its resident sea turtles. The water is exceptionally clear, and it's said that you have a relatively good chance of spotting turtles grazing on seagrass while snorkeling right off the beach.

Like Aharen, this beach sits within a bay with calm waves. It's popular among divers, but since no public bus reaches it, it's difficult to visit independently. Joining a tour with transportation included makes it much easier to get here.

How to Choose Your Plan and What to Prepare

You can choose between a swimming-only plan or a swimming-plus-snorkeling package, and select from two beaches: Aharen or Tokashiku. If you want more time on the beach, a high-speed boat round trip is worth considering.

You're advised to wear your swimsuit under your clothes before the tour begins. It's also handy to bring a change of clothes, a bath towel, and sunscreen. If you're prone to seasickness, it's recommended to take motion sickness medication about 30 minutes before boarding.

At each beach, optional equipment such as snorkel sets, parasols, and kayaks is available locally, with applications and payment handled on-site. For details, please check the booking page.
