Kerama Islands Half-Day Whale Watching Tour from Naha

Naha harbour and the run to the Keramas

The trip starts with pickup from your hotel or chosen point in Naha, up to 60 minutes before departure, followed by a short transfer to the harbour. After a safety briefing and life jacket fitting, the boat leaves the breakwater and heads west across the open sea towards the Kerama Islands, a run of roughly 40 to 60 minutes depending on where the whales were last seen.

On the way the guide explains the whales' migration and what to look for: a puff of spray on the horizon, a dark back rolling at the surface or a splash of white water. Everyone on board helps to watch, and this Kerama Islands whale watching tour often finds its first whale before the islands are reached.

The Kerama Islands: a winter nursery

The Kerama Islands, about 40 km west of Naha, are a cluster of small, steep islands whose sheltered, warm waters make one of the main humpback breeding grounds in the North Pacific. The whales were once hunted here, but since hunting stopped they have returned in strong numbers, and whale watching around the Keramas has been an important winter activity for local islanders for more than three decades.

The islands became a national park in 2014, protecting both the land and the surrounding sea. From the boat you see their forested ridges and white beaches rising out of the clear 'Kerama blue' water, and the guides use high viewpoints on the islands and radio contact with other boats to find where the whales are on each trip.

Humpback whales up close

Humpback whales spend the summer feeding in the cold waters of the northern Pacific and travel thousands of kilometres south to Okinawa to breed. Adults reach 13 to 15 metres and weigh around 30 tonnes, yet they are famously acrobatic: they leap clear of the water in a breach, slap the surface with their long white flippers and lift their tails high before deep dives. Each tail's pattern of black and white is unique, so researchers identify individual whales by photographing it.

Mothers with newborn calves rest in the calm water near the islands, while males sing long, complex songs that can last for hours. The boat follows strict rules on distance and speed, so the whales are never chased. Sightings are frequent in season, but whales are wild animals and their behaviour is never guaranteed.

Best time for whale watching in Okinawa

The humpback season around Okinawa runs from late December to early April, with the most whales usually seen in February and early March. Morning departures often have calmer seas, while afternoon trips suit late risers and leave the morning free for Shuri Castle Park or the Tsuboya pottery district. Booking at least two days ahead secures your hotel pickup.

Winter in Okinawa is mild, around 15 to 20 degrees, but the north wind on deck feels cold, so bring a warm layer and a windproof jacket. Seas can be choppy, so take seasickness medicine before boarding if you are sensitive. If wind or waves make the trip unsafe, it is cancelled and we help you rebook or refund.
