REVIEW · JAPAN SNORKELING TOURS
Okinawa:Naha:Kerama Island Experience 1Dive and Snorkeling
Kerama’s famous blue water is the main event here. From the boat, you can see the seafloor below, then enter for an introductory scuba session and snorkeling at three different spots. It is a lively day in the sea, not a quick dip beside the harbor.
I like the careful teaching and the chance to try both activities in one outing. I also like the friendly, calm support from staff members such as Tina and Christina, especially for first-timers who need help with breathing or equalizing. The main drawback is that conditions control the day, and some planned activities, including a beach stop or high jump, may not happen.
Kerama Blue in Three Specific Stops

- One introductory scuba session: Learn the basic skills on land, practice again at the surface, then go underwater when you feel ready.
- Three boat locations: You can snorkel at three Kerama sites, with the possibility of another underwater session if conditions and the schedule allow.
- Seasonal whale watching: From January 12 through March, the boat also searches for whales, though sightings are never guaranteed.
- A beginner-friendly support system: Instructions come verbally, after equipment setup, and in the water, with staff ready to help nervous swimmers.
- Useful extras included: Gear, towels, boat fee, insurance, tea, hot-water showers, changing facilities, and toilets are included.
- Free underwater memories: The crew takes about three underwater photos and videos at no extra charge. A GoPro with an SD card costs ¥3,000 if you want more control.
Why This Day Works for First-Time Scuba

The strength of this Okinawa boat trip is its mix of gentle instruction and real sea time. You do not simply receive equipment and get pushed overboard. The staff first explain the process in words, then show you how the equipment works after it is set up, and finally repeat the key points in the water.
That three-stage approach matters. Scuba can feel strange at first, especially when you need to breathe through a regulator or clear your ears. The instructions continue after you enter the water, so you can deal with each step at the right speed.
You start by practicing on land. At the surface, you repeat the skills until the equipment feels less foreign. Only then do you move below the surface. This is a sensible pattern for a first session, and it gives you a chance to stop and ask for help.
The staff’s calm manner is one of the most valuable parts of the day. Christina is specifically praised for noticing when someone needed extra support, while Tina helped a less confident swimmer enjoy the outing. That sort of quiet attention is more useful than a loud pep talk when you are nervous in open water.
Still, do not mistake a beginner session for a completely effortless activity. You need to be comfortable in the sea, able to follow instructions, and in good health. Equalizing can be a concern for some people, and you should tell the staff early if you are worried. The crew can help, but they cannot remove every physical demand.

The Boat Ride Out From Naha

The tour includes the boat boarding fee, equipment, towels, and transport according to the experience details. Hotel pickup is also described in the feedback, so confirm the exact pickup area and meeting instructions when you reserve. The day is built around moving between three sites rather than staying in one patch of water.
That movement gives you variety. If your first stop feels intimidating, the next one may offer a better chance to settle in. One person who initially became frightened at the first scuba location was able to try again at the second after receiving help from the guide.
The boat itself is your base between water sessions. You return aboard to talk through what you saw, rest, and prepare for the next stop. Tea, towels, a changing room, toilet, and hot-water shower are included, which makes a real difference after repeated time in the water.
Motion sickness medicine is provided free. I would still bring your usual remedy if you have one and know it works for you, but the included service is a thoughtful touch. A boat crossing can feel very different from calm snorkeling near shore.
The schedule can also change with weather and sea conditions. You may see a white-sand beach or have the chance to jump from a height of four meters, but neither is promised. These are bonuses, not reasons to book the day.
What Happens at the First Water Session

At the first location, expect a short period of adjustment. You look down and may be able to see the bottom clearly through the clean water. Fish can approach close to your feet and face while you remain at the surface.
The staff then guide you through the skills you practiced on land. Once breathing and movement feel manageable, you can try going below the surface for the introductory scuba session. The point is not to race to depth. The point is to become comfortable enough to notice the coral and fish around you.
That slow beginning is especially important if this is your first time. Many people feel excited and nervous at once. I like that the staff do not treat nervousness as a failure. The water-based explanation lets you learn in the exact setting where the skill matters.
The underwater views are the reward. You can expect coral formations and schools of fish, though the exact marine life varies with the site and conditions. Turtles have been seen during the experience, but no wildlife sighting is guaranteed.
The included underwater images are a nice bonus. About three photos are provided, enough to preserve the memory without forcing you to manage a camera while learning. If you want more footage, a GoPro and SD card can be rented for ¥3,000.
Snorkeling Across Three Kerama Sites

Snorkeling gives you a second way to enjoy the water and lets you stay near the surface if scuba does not feel right. The boat visits three locations in one day, so you get more than one view of the Kerama Islands.
Each stop can feel different because visibility, coral, fish, and current change from place to place. The route may include a more enclosed or cave-like passage at the final location, based on the experience described by one participant. Do not expect every feature on every departure, since the crew must follow sea and weather conditions.
You might see a turtle, colorful fish, or broad coral areas. The most memorable part for many people is often the closeness of the fish. Looking down from the surface, you may see the bottom clearly, then find fish moving close to your mask once you enter.
You should be reasonably confident in the water, but you do not need to arrive as an expert swimmer. Staff can support a less confident participant, and free swim rings are available if reserved in advance. That reservation requirement matters, so request one before the day rather than assuming one will be waiting.
The three-stop format is also good for families with mixed interests, within the age and health restrictions. One person can enjoy surface snorkeling while another tries the introductory scuba session. Everyone still shares the boat ride and the same sites.

The Seasonal Whale Watching Add-On

From January 12 through March, the outing includes whale watching as part of the seasonal Kerama program. Winter is the only stated period for this extra activity, so do not expect it on an August or summer departure.
The crew has a strong chance of finding whales, but the conditions can still win. Wind, waves, and animal behavior are beyond the operator’s control. You should treat whale watching as a worthwhile possibility, not a guarantee.
This seasonal version packs several activities into one day: boat travel, whale watching, one introductory scuba session, and snorkeling. That makes it particularly attractive if your Okinawa trip falls within the winter window and you want one sea-focused day rather than separate bookings.
The tradeoff is a fuller, busier schedule. You will spend much of the day moving between activities, so this is not the right choice if you want a quiet beach afternoon. It is designed for people who enjoy variety and do not mind returning to the water several times.
August Shaved Ice and Other Small Extras

The operator provides shaved ice in August and September. That is a small detail, but it makes sense after time in the sun and salt water. Motion sickness medicine is free, and towels, tea, showers, and changing facilities are part of the package.
Lunch is not included. You can order it for ¥880, and the onboard meal has been described as tasty and filling. Ordering ahead is required, so decide before the day rather than expecting to buy lunch casually while aboard.
A free swim ring is available with a reservation. A GoPro with an SD card costs ¥3,000. These options help you tailor the day without paying for extras you do not need.
You only need to bring a swimsuit according to the short packing note, but the fuller guidance also lists sandals, sunscreen, and a change of clothes. I would bring all four. Sunscreen is particularly important on a boat, where reflected light can catch you even when the air feels breezy.
Is $100 Good Value?

At $100 per person, the price is strong for a full sea day that includes one introductory scuba session, snorkeling at three locations, equipment rental, towels, insurance, tea, hot water, facilities, and the boat fee.
The value improves if you use several included services. A first-time participant gets instruction, equipment, staff support, and underwater photos without separate charges. The whale watching period adds even more value from January 12 through March.
Lunch costs an additional ¥880, and a GoPro costs ¥3,000. Those are clear optional expenses, not surprise charges. If you already have a camera, skip the rental. If you want a simple onboard meal, the lunch price is reasonable.
The price does not guarantee perfect visibility, a turtle, whales, or a specific coral site. It also does not include landing on an island. You are paying for a guided boat experience across the Kerama waters, not a shore excursion with a long island visit.
Who Should Book This Kerama Trip?

I would choose this for a first-time scuba participant who wants plenty of support and a full day on the water. The repeated instruction, small-group approach, and staff attention are more important here than technical certification.
It also suits couples or friends who want different levels of activity. One person can snorkel while another tries the introductory scuba session, then everyone can regroup aboard the boat. The free photos are useful for a shared memory, especially if nobody wants to manage a camera.
The experience is not suitable for children under the listed age limits, pregnant women, wheelchair users, or people with heart, respiratory, kidney, or other pre-existing medical conditions. The information gives several age restrictions, including under 8, under 10, over 70, and over 95, so contact the operator to confirm the rule that applies to your party.
You should also avoid booking if you have a cold, recent surgery, high blood pressure, claustrophobia, or a condition that makes scuba or open-water activity unsafe. Alcohol, drugs, smoking in the vehicle, fishing, surfboards, pets, weapons, sharp objects, fires, and littering are not allowed.
The cancellation terms are worth reading before payment. The published details give a full refund for cancellation up to 24 hours ahead, while another schedule lists a 50 percent charge after noon two days before, rising to 100 percent after 5 p.m. the day before, on the day itself, or with no notice. Because those time windows conflict, confirm the exact policy at booking.
Should You Book It?

Book this experience if you want an active Kerama day with one introductory scuba session, three snorkeling locations, and patient guidance. It is especially appealing in winter, when whale watching is added, and it offers good value for people who will use the included equipment and services.
Skip it if you want guaranteed whale sightings, a relaxed beach day, or a simple shore-based activity. Weather controls the route, and the open water may feel demanding. For a healthy beginner who wants a well-supported first try, though, the mix of coral, fish, boat travel, and calm instruction makes this a strong Naha choice.
