Naha: Full-Day Introductory diving & Snorkeling in the Kerama Islands, Okinawa
The sea turns glassy blue here. This full-day trip takes you from Naha to the Kerama Islands National Marine Park, where first-time scuba guests can see coral, tropical fish, and possibly turtles in famously clear water. I like the mix of one introductory scuba session and free snorkeling, plus the chance to visit two or three sites in one day. I also like the small maximum group of four, though pickup communication and strict health rules deserve careful attention.
The setting is the star, but the crew adds plenty. Guides stay close to beginners, the boat has room to relax, and lunch, drinks, towels, and equipment are included. The main drawback is physical effort: swimming can leave your arms sore, and rough seas can cause serious motion sickness. Bring medication with you, since it is not included.
Key things to know before you book

- Two to three Kerama sites in one day: You get more than a single short swim, with different coral and fish areas to explore.
- One beginner scuba session included: No previous scuba background is required, and the guides provide instruction before entering the water.
- Free snorkeling after scuba: You can keep swimming around the boat without paying for another scuba session.
- Small group size: The stated maximum is four people, which matters when you need close help in the water.
- Turtles are seen often: The area is known for regular turtle sightings, while humpback whales visit during winter.
- Extra scuba costs ¥6,000: Lunch, gear, towels, and pickup at designated locations are included, but a second scuba session costs extra.
Why the Kerama Islands are worth the boat ride
From Naha, the Kerama Islands are about an hour away by boat. That travel time is not just a transfer. It moves you from the city to a protected marine area with unusually clear water and 248 recorded coral species.
The islands became a National Marine Park in 2014. That protection helps explain why the underwater scenery is the main reason to book this outing. You are not simply swimming in a convenient spot near Naha. You are heading to a place known for coral gardens, small tropical creatures, larger fish, and frequent turtle sightings.
The scenery changes through the year. Winter brings humpback whales to the reserve for breeding, although whale sightings are not promised as part of the trip. Other seasons offer their own underwater sights, and the operator presents the area as a year-round marine destination.
I like that you can tell your guide what you most want to see. That does not guarantee a turtle or a particular fish, but it gives the crew a chance to shape the day around your interests and current sea conditions.

Starting at 8:00 am in Naha
Your morning begins at Marine Club Berry Naha, at 2-chōme-3-13 Minatomachi. Check-in and equipment fitting take place before you board. A free pickup and drop-off service is available from designated locations, but you need to request it when booking.
This early start makes sense. The trip lasts about eight hours, and the Keramas are roughly an hour from Naha. You need time for the boat ride, safety briefing, one scuba session, snorkeling, lunch, and visits to multiple sites.
If you arrange pickup, confirm the exact place and time clearly. One serious complaint involved a missed hotel transfer and poor communication. The available information does not show how common that problem is, but it is enough reason to keep the meeting point and the operator’s contact details handy.
At the shop, you get fitted for scuba and snorkeling equipment. You should bring your own swimsuit. A bath towel is supplied, and the boat has soft drinks and a lunchbox for the break between swims.
Your first underwater session

Before entering the water, the guides explain the basic rules and safety procedures. This is important for a first scuba experience because the equipment, breathing method, and underwater signals can feel unfamiliar even to a confident swimmer.
The strongest praise for this trip centers on the crew’s patience. Families with children and people trying scuba for the first time have received close support from guides who stayed with them step by step. English is spoken by the guides, though communication may be more difficult with some crew members.
One guide named Noah received especially warm praise for being welcoming and passionate about the work. That kind of attitude matters more than polished sales talk when you are standing on a boat in full equipment, wondering if you can manage the first few minutes below the surface.
The included session is an introductory experience, not a full certification course. Think of it as a guided first taste of scuba in a controlled setting. You are there to enjoy the reef while the staff handles the technical side and keeps an eye on your comfort.
You should still take the physical requirements seriously. The operator asks for a strong level of physical fitness, and swimming can be more demanding than expected. One person reported strong arm pain afterward because there was not much warm-up before getting into the water.
That point is easy to overlook. Clear water and colorful coral may sound gentle, but you still need to move, float, handle equipment, and stay alert for an extended period. If you are not a strong swimmer or have concerns about exertion, ask the operator before booking.
Snorkeling keeps the day going
After the included scuba session, you can pay for another one or snorkel free around the surrounding area. For most first-timers, the free snorkeling option is a good value. You get more time in the water without adding another ¥6,000 charge.
The snorkeling also gives you a second way to enjoy the reef. You can remain near the surface, watch fish and coral from above, and continue exploring without the same equipment or instruction required for scuba.
Several people praised the amount of time spent in the water. That is one of this outing’s biggest strengths. Some boat trips spend long stretches moving between sites with only a short swim at each stop. Here, the plan includes one scuba session, free snorkeling, and two or three total locations.
The exact order and sites can change with weather and sea conditions. That flexibility is sensible in a marine park, but it means you should not expect a fixed list of named reefs. The value comes from seeing several parts of the Keramas rather than checking off one specific location.
Turtles are spotted daily according to the tour description, but wildlife is never guaranteed at the exact moment you enter the water. You may see tiny reef creatures, tropical fish, larger fish, coral, and perhaps a turtle. During winter, you may also have a chance to notice humpback whales in the wider reserve, though the day’s focus remains the underwater sites.

What the two or three stops add

The Keramas offer more than one kind of seascape. Visiting two or three spots gives you a better sense of the area’s variety and reduces the risk that one ordinary patch of reef defines the whole day.
One site may appeal through coral and small fish. Another may offer better visibility, larger fish, or a different shape of reef. The operator chooses locations according to conditions and the group, so the exact experience is not identical every day.
This arrangement also helps beginners. If the first water entry feels awkward, you have another chance to settle in. If you are already comfortable, the later snorkeling time lets you enjoy the setting at your own pace.
The boat itself is part of the experience. People have praised its comfortable layout, open upper area, and views while moving between sites. Between swims, you can sit on deck, drink a soft beverage, and eat the supplied lunchbox.
Do not expect a luxury cruise. This is a working boat for a full day on the water. Still, having room to rest makes a real difference when you are wet, tired, and waiting for the next entry.
Price and what you actually get for $72.48
At $72.48 per person, the trip offers solid value if you want a full day rather than a short introductory session near shore. The price includes scuba equipment, snorkeling equipment, one introductory scuba session, lunch, a bath towel, and designated-location pickup service.
You also receive free snorkeling after the scuba session. That matters because a second scuba session costs ¥6,000. If your main goal is simply more time in the sea, you can avoid that extra cost and still spend much of the day in the water.
The included lunch and drinks are practical rather than a reason to book on their own. You do not need to arrange food for a long day away from Naha, and you can refuel between swims.
The small maximum group of four adds value. A beginner benefits from having a guide nearby, especially during the first underwater session. A small group can also feel calmer than a large boat where everyone enters the water at once.
There are extra costs and omissions to remember. Your swimsuit is not supplied, motion sickness medicine is not included, and the extra scuba session costs ¥6,000. Photos are sent through a download link after the outing, which is a pleasant bonus, but you should not treat the photo service as the main reason to pay for the trip.
Health rules, sea conditions, and the fine print

The health screening is strict. Pregnant people cannot join, and anyone taking medication may need doctor approval. One person was refused scuba participation after disclosing medication because the company’s policy treats any medication as a possible concern unless a doctor clears it.
If you take prescription or regular over-the-counter medicine, contact the operator before booking. Do not wait until check-in. Even if you feel perfectly healthy, the company may apply its policy conservatively.
Sea conditions also deserve respect. One person became very sick when the water was rough, while the crew provided patient help. Take suitable motion sickness medicine before the trip if you are prone to seasickness, and ask a pharmacist or doctor about what is appropriate for you.
The weather policy says the outing can be canceled in poor weather, with a different date or full refund offered. That sounds straightforward, but weather judgments can be frustrating when conditions feel unsafe to you yet the operator continues. If storms are forecast, contact the company directly and clarify the decision process.
You can cancel for a full refund up to 24 hours before the start time. Changes or cancellations inside that period are not accepted under the stated policy.
Who will enjoy this outing most?

This is a good choice for a fit first-timer who wants to try scuba without committing to a course. It also suits couples and families who want a full day at sea, especially when some people prefer scuba and others would rather snorkel.
The trip works well if you value time in the water, not just photographs from a boat. You receive one guided scuba session and can continue snorkeling afterward, which makes the day feel active and worthwhile.
It is less suitable if you dislike boats, become seasick easily, or want a relaxed beach day with little exertion. You should also reconsider it if you have a medical condition or take medication and cannot obtain the required approval.
The maximum group of four is a strong point for nervous beginners. Still, do not assume that a small group removes every challenge. You must be comfortable in open water and able to manage a physically active day.
Should you book the Keramas scuba and snorkeling trip?
I would book this if your priority is a first scuba experience in one of Okinawa’s best-known marine areas, with plenty of snorkeling time afterward. The coral, clear water, turtle sightings, friendly instruction, and two or three sites give the day more substance than a quick introductory session.
Before paying, confirm three things: your pickup arrangement, your medical eligibility, and your plan for seasickness. Bring your swimsuit, consider motion sickness medicine, and expect your arms and shoulders to work harder than the brochure-style scenery suggests.
At $72.48, the package is strong for a full eight-hour outing with equipment, lunch, towels, and a small group. If you are healthy, reasonably fit, and eager to see the Keramas below the surface, this is a practical way to begin.
