Both Zamami and Tokashiki are part of the Kerama Islands, both leave from Tomari Port in Naha, and both have the clearest water you'll find in Okinawa. The choice comes down to what you want from the day: Zamami has the better reef snorkeling and sea turtle encounters, Tokashiki has the wider white-sand beach and works better as a day trip. If you have two nights, do both.
Here to snorkel? Zamami. Furuzamami Beach has coral right off the shore and Ama Beach has sea turtles at high tide. Here for the beach? Tokashiki. Aharen Beach is wider, whiter, and calmer. Only have one day? Tokashiki. The Marine Liner gets you there in 40 minutes, giving you more time on the sand. Staying overnight? Zamami. After the last ferry takes the day-trippers back to Naha, you'll have the reef to yourself.

Where does Zamami win?
Snorkeling is the clear answer. Furuzamami Beach has shallow coral starting a few meters from the sand, and the reef is full of tropical fish within wading depth. You don't need a boat tour or even fins to see something worth your time. Ama Beach, a 10-minute walk from the port, is where sea turtles feed during high tide. You can swim alongside turtles right from shore, no boat tour needed.
Zamami is also the better overnight island. It's small enough to walk across in an hour, and scooter rentals are available on the main street near the port. The guesthouses serve dinner (book ahead), and the pace drops to near-zero after the last ferry leaves. If you're here to unplug and spend a full day in the water, Zamami earns the overnight.
Where does Tokashiki win?
Aharen Beach is the wider, whiter, more classically beautiful beach. The sand stretches further, the water is calm, and there's a village bus from the ferry port for ¥400. As a pure beach day, Tokashiki delivers more space and better swimming conditions than Zamami. The snorkeling is decent but shallower, and the reef is less dramatic than Furuzamami's.
Tokashiki also works better as a day trip because the Marine Liner high-speed ferry takes 40 minutes, compared to Zamami's 50. That extra 20 minutes round trip adds up when you're trying to maximize beach time. Both islands have limited accommodation and food: guesthouses and pensions, a handful of restaurants that close early. Book your guesthouse meals in advance regardless of which island you pick.
How do you get there?
Both ferries leave from Tomari Port in Naha, a short taxi or monorail ride from the hotel district. The Queen Zamami high-speed ferry runs to Zamami (50 minutes, about ¥3,200 one way) and the regular ferry takes about 2 hours for roughly ¥2,150. The Marine Liner Tokashiki runs to Tokashiki (40 minutes, about ¥2,530) with a regular ferry at 70 minutes for about ¥1,690.
The Queen Zamami sells out every summer weekend. Book as far ahead as possible, especially for Saturday departures. Tokashiki's Marine Liner has slightly less demand but still fills up during peak season. Both ferries can be canceled in bad weather, particularly during typhoon season from August through September. Have a backup plan for your Naha day if the boats aren't running.

Can you do both?
With two nights in the Keramas, yes. Stay overnight on Zamami, take the inter-island ferry (called the Mitsushima) to Tokashiki the next morning, spend the day at Aharen Beach, and catch the afternoon Marine Liner back to Naha. The Zamami-to-Aka leg runs several times daily without reservation (about ¥300, 15 minutes). The Zamami-to-Tokashiki leg requires advance reservation by 5pm the day before. If nobody books, it doesn't run. Reserve at the Zamami Port office or call ahead.
If the Keramas leave you wanting more island time, Ishigaki and Miyako are the next step. Ishigaki adds jungle, mangroves, and its own ferry island network. Miyako has the beaches that make postcards. Both are a short flight from Naha. Our beaches and snorkeling guide covers all the car-free options, including how the Keramas compare to the main island's spots.
