Naha:Kerama Islands 2 Fun Dive/Whale watching Limited time

Blue water, big islands, and whales in winter. This full-day outing takes certified scuba participants from Naha to two or three sites around Tokashiki, Zamami, or Aka Island. I like the high-speed boat ride between islands and the chance to request a focus such as turtles, small fish, big fish, or underwater rock formations. I also like that equipment, towels, hot water, and Naha transfers are included. The main catch is simple: you need a C-card, and the day can be tiring if you are prone to seasickness.

The experience costs $140 per person and lasts about seven hours. That is a fair price for a boat-based trip with tanks, weights, full rental equipment, an instructor, and winter whale watching included from mid-January through March. Still, bring your own lunch, confirm pickup carefully, and remember that whales and specific sites depend on weather and sea conditions.

Key points to know before booking

• Two or three Kerama sites: The route usually centers on Tokashiki, Zamami, and Aka Island, with the exact locations chosen according to conditions and your interests.
• Whales from January through March: Whale watching is included on the Kerama route from January 12, with the detailed operating note specifying January 15 through March 31. Sightings are likely, not guaranteed.
• Certified participants only: You must hold a C-card and bring your certification and dive log.
• Full equipment included: Tanks, weights, rental gear, towel, tea, changing room, toilet, hot water shower, and a boat coat are provided.
• Useful winter comfort measures: A 5mm one-piece suit, 3mm hooded vest, heated cabin, engine heater, and boat coat help on cooler days.
• Naha pickup only: Hotel pickup and drop-off are available within Naha city. Elsewhere, you meet and finish at the local departure point.

Leaving Naha for the Kerama Islands

Your day begins early. The boat departs at 8:00 AM, and the operator sends the pickup time by email the day before. You need to wait outside your Naha hotel, so check your messages and hotel address carefully. If you do not provide a clear location, you may be expected to meet locally.

The transfer service is limited to Naha city. That is convenient if you are staying near the city center, but it is not a door-to-door service for hotels outside Naha. If you drive to the port, customer parking is available, with paid parking listed at 500 yen per day when meeting there.

The published schedule includes van travel before and after the boat portion, with the total outing lasting about seven hours. The exact shape of the day depends on the sea route, site conditions, and how much time the boat spends moving between locations.

The fast boat ride is part of the appeal. You will see other islands as you travel across the water, and the ride gives you a sense of how spread out the Kerama group is. It also means you should prepare for wind and spray. Sunglasses, sunscreen, swimwear, dry clothes, and seasickness medicine are sensible additions to your bag.

Choosing your underwater focus

This is not a fixed sightseeing route with the same three stops every day. The crew mainly works around Tokashiki, Zamami, and Aka Island, then selects the best available points for that day. Wind, waves, visibility, and current can all affect the plan.

You can write requests in the booking comments. You might ask for large fish, small fish, turtles, underwater terrain, or another interest. The crew will try to match the route to your level and wishes, but the final decision belongs to the staff because safety and sea conditions come first.

That flexible approach is useful for experienced certified participants who want a certain type of underwater scenery. It also helps people returning to scuba after time away. The instructors aim to adjust the pace and explain things clearly, and English and Japanese support is available.

The experience is best understood as two main underwater sessions, with the possibility of a third site depending on the day. Some outings also include snorkeling after lunch. The exact balance is not guaranteed, so you should ask about the planned number of sessions if that detail matters to you.

What the two or three sites offer

The Kerama Islands are known for clear water and varied marine life. The available experience includes the chance to see many kinds of fish, sea snakes, turtles, and small sharks. One outing also included a whale sighting from the boat on the return to Naha, which shows how much extra wildlife interest the route can add in winter.

The first site is usually where you settle into the day. You will check your equipment, enter the water, and get a feel for visibility, current, and water temperature. If you have not used your gear recently, tell the instructor before entering. This is exactly the sort of situation where a patient guide can make the outing more comfortable.

The second site gives the day its main variety. You may find another reef setting, rock formations, or different marine life, but the exact character changes with the route. The operator owns two boats, which helps it plan around the day’s conditions and respond to requests where possible.

A third site may be included when time and sea conditions allow. Do not treat it as a promise of three full underwater sessions. The description says two to three points, while customer accounts describe two morning sessions followed by snorkeling. That makes it wise to clarify what your booking includes if you are planning around a strict number of sessions.

The Chibishi Islands are not included. That matters if you have seen other Naha boat trips advertised around those islands. Here, the focus is the Kerama route around Tokashiki, Zamami, and Aka.

Winter whale watching from January to March

From January through March, whale watching is included on the Kerama route at no extra charge. The information gives two start dates, January 12 and January 15, while the operating period is stated as running through March 31. Confirm the exact date for your departure when booking.

The boat crew may watch for humpback whales while traveling between the islands or returning to Naha. You could hear whales or see them from the boat, but nature does not follow a timetable. Weather, waves, visibility, and whale behavior can prevent a sighting even when the crew makes every effort.

This seasonal feature adds real value to a winter trip. You are already going offshore for the underwater sessions, so whale watching does not require a separate boat ticket or another day. It also gives non-underwater moments a clear purpose during the ride.

Winter conditions need not mean a miserable day on the boat. The stated water temperature around the Kerama Islands does not fall below 22°C, while the average winter air temperature in Okinawa is around 20°C. The operator uses a 5mm one-piece suit with a 3mm hooded vest, plus a free boat coat, cabin heater, and engine heater. The cabin is kept at about 25°C.

Hot Okinawa soba and oden are provided for lunch according to the winter comfort information, but the bring-along instructions also tell you to pack lunch. To avoid confusion, ask what lunch arrangement applies to your date. On January 1, the operator holds a traditional mochi-pounding event with all-you-can-eat mochi for people who order lunch.

Summer extras: shaved ice and swim rings

August and September bring a different kind of comfort: shaved ice service. That is a small touch, but a welcome one after time in a wetsuit and warm tropical air.

Free swim-ring rentals are also available, but you must reserve one in advance. This is useful if someone in your group wants a relaxed float between activities. It is not a substitute for swimming ability or an arranged safety service, so make the request when booking rather than hoping one will be available on the day.

A rental camera is included only by reservation. If you want photographs, ask for it ahead of time. A GoPro costs 3,000 yen with an SD card, while a rental camera SD card costs 2,000 yen. You may bring your own SD card for the camera, which can reduce the extra cost.

One customer specifically praised the pictures included with the outing. That makes the camera option worth considering if you want a record of turtles, fish, or the clear water without handling your own camera underwater.

Equipment, staff, and comfort on board

The $140 price includes full rental equipment, including tanks and weights. It also covers a towel, tea, changing room, toilet, hot water shower, and boat coat. Those inclusions matter because buying or transporting your own gear can add cost and hassle during an Okinawa trip.

The operator also provides pickup within Naha. Add the value of the boat, staff, tanks, and basic facilities, and the price is reasonable for a full-day Kerama outing. It is less attractive if you already have a boat, tanks, and transport arranged, but most visitors will not.

The instructors are described as veteran staff who can support people who have not been underwater for a while. One customer singled out a female instructor for being kind and attentive. Another praised the staff as professional and the boat as clean and well equipped. Those are important qualities on a day when you depend on the crew for gear checks, boat movement, and water entry.

The trip can run even with one participant, so solo bookings are accepted. Special arrangements such as a birthday or commemorative underwater session can also be requested. These plans need to be discussed in advance rather than assumed to be part of the standard program.

Who should book this experience

This trip fits you well if you:

• Hold a current C-card and want a boat trip from Naha
• Prefer small-group attention and the option to request marine-life themes
• Want equipment and Naha transport included
• Like the idea of combining underwater sessions with island scenery
• Are visiting between January and March and want a chance to watch whales
• Are returning to scuba after a break and want instructor support
• Are traveling alone and need an operator that accepts single bookings

It is not suitable for uncertified participants. Children under 10, pregnant women, wheelchair users, people with mobility limits, and people with heart, respiratory, kidney, blood pressure, diabetic, epilepsy, vertigo, recent surgery, or other listed medical concerns should not book it. People with a cold are also excluded.

Minors need parental consent. The program does not accept unaccompanied minors, and people over 95 are not eligible. The operator also prohibits alcohol, drugs, smoking in the vehicle, fishing, touching marine life, and bringing pets except assistance dogs.

Practical tips for a smoother day

Bring your C-card and dive log, even though the operator provides the tanks and weights. Pack sunglasses, sunscreen, swimwear, a change of clothes, personal medication, and lunch unless you have confirmed another arrangement.

Take seasickness medicine before departure if you are prone to motion sickness. The high-speed boat and open-water conditions can be demanding, and waiting until you feel ill is usually too late.

Write your preferred marine-life subjects in the booking comments. Ask about the camera, swim ring, lunch, and any special event at the same time. If you need the winter loan coat or have concerns about staying warm, tell the staff early because supplies are limited.

The destination can change suddenly, or the entire plan can be canceled because of weather and sea conditions. Free cancellation is available up to 24 hours before departure, but same-day changes caused by nature are part of the reality of an offshore excursion.

Should you book the Kerama trip?

Book it if you are certified, want a reasonably priced boat outing from Naha, and care more about good conditions than a guaranteed list of sites. The strongest points are the clear Kerama waters, the flexible site selection, attentive instruction, included equipment, and the added chance of whales in winter.

Think twice if you need a guaranteed three-site schedule, cannot handle boat motion, or want a simple shore-based activity. You should also confirm the lunch plan and pickup details before paying.

For the right participant, this is a practical way to spend a full day around Tokashiki, Zamami, and Aka. Bring your certification, prepare for changing sea conditions, and let the crew choose the safest, most rewarding route.
