Located on Tokashiki Island, Aharen Beach is the easiest snorkeling excursion within the Kerama Shoto National Park boundaries. With its clownfish, butterflyfish, bright corals, giant clams and hundreds of other marine species, Aharen gives a fine glimpse of Okinawa’s reef life.

Update: a large part of Aharen Beach coral reef is currently closed. The protected area is marked by buoys and a rope, and a supervisor on the beach ensures that snorkelers respect the regulations. We do not know whether this measure is temporary or not. In the meantime, know that large areas of the reef can no longer be snorkeled. Most of the pictures on this page have been taken outside the current authorized snorkeling areas, before the actual regulations.

How to get to Aharen Beach snorkeling spot?

Aharen Beach is located on Tokashiki Island, one of the most visited islands in the Kerama archipelago. Most tours to the islands depart from Naha, Okinawa’s capital city, which is the archipelago’s gateway.

Boats to the Kerama Islands, including tours to Tokashiki, leave from Tomari harbor, next to the city center. The closest monorail stop is Miebashi (美栄橋), a 10 minutes walk to the jetty. The express boat is the most convenient (a 35-minute ride to reach the island) but you might prefer the cheaper ferry (70 minutes).

The easiest way to reach Aharen Beach from Tokashiki island jetty is the bus shuttle waiting for passengers each time a boat arrives (¥400 per person per trip). You can also rent a vehicle or grab one of the island’s rare taxis. Aharen is a tiny village, you will have no trouble finding its adjacent beach.

Aharen Beach snorkeling tips and recommendations

There are only 2 areas where snorkeling is allowed at Aharen Beach: the overcrowded (supervised) Swimming area (area 1 on the map, life vest compulsory) and the much less crowded (unsupervised) Restricted Swimming area (area 2 on the map).

The threadfin butterflyfish is easy to spot at this location.

Area 2 is definitely the best for snorkeling, as it is larger, deeper, and features more coral patches. Snorkeling from the beach you will first cross sandy areas (↕2-3ft/0.5-1m), then reach the reef area (3-12ft/1-4m).

Aharen Beach reefs are overall well preserved, although some areas can be damaged. In the best-preserved areas, vibrant, bright-colored gardens await snorkelers. These areas support rich underwater life, including blue damselfish, pairs of butterflyfish, Moorish idols, and giant clams.

Coral reef at Aharen Beach
Some parts of the reef are lively and colorful.

Several clownfish species can be spotted in the area, but you are most likely to see the tomato clownfish, which is found even in very shallow areas (less than 3 ft/1 m deep). However, if you love those cute creatures, don’t miss a visit to Furuzamami Beach where they literally abound.

Most of the time Aharen Bay is sheltered from waves and currents, hence it is ideal for beginners. Mind the boat channel before entering the water: it is located on the spot’s central part, between the two snorkeling areas.
