Aharen Bay, Okinawa

How to get to Aharen Beach snorkeling spot?

Naha will probably be your first step in Okinawa: it is also the departure point to Tokashiki Island. Head to Tomari harbor, it is close to the city center (the nearest monorail stop is Miebashi (美栄橋); you will then have to walk for about about 10 minutes to the jetty). There are several options to reach the Kemara archipelago. The express boat is most convenient (35 minutes, round trip about $40) but you might prefer the cheaper ferry (70 minutes, round trip about $25). Schedules depend on the season. Be careful, as there can sometimes be only one or two round trips per day.

The easiest way to reach Aharen beach from Tokashiki island jetty is the bus shuttle waiting for passengers each time a boat arrives (about 20 minutes, Y400/single trip). You can also rent a vehicle or take one of the island’s rare taxis. Aharen is a tiny village, you will have no trouble finding its adjacent beach.

Entering the water at Aharen Beach

Our advice: enter the water on the western part of the beach, on your right when facing the sea.

Aharen Beach snorkeling tips and recommendations

When you leave the beach you will first swim across monotonous sandy areas (↕2-3ft/0.5-1m), then reach the reef area (3-12ft/1-4m). Water depth increases significantly beyond the reef.

Coral reef at Aharen, Tokashiki Island

Aharen beach reefs are overall well preserved, although some areas have regrettably decayed. In the best preserved areas, coral formations build delicate shaped, bright colored gardens. Underwater life thrives in them: fluorescent blue damselfish swimming above coral, couples of butterflyfish, Moorish idols, giant clams nesting in crevices… Several clownfish species can be spotted in the area. You are most likely to see tomato clownfish, which is not afraid of shallow areas (often seen in less than 3ft/1m deep). However, if you love those fascinating fishes, head instead to Furuzamami Beach where they literally abound.
