From Naha Scuba Diving Trip in Kerama(for certified divers)

Kerama’s blue water rewards an early start. This eight-hour trip from Naha combines small-group scuba outings with clear English briefings, hotel transport, rental gear, and free underwater photos. I especially like the careful pickup service and the chance to add a third descent for 5,500 yen. The main consideration is the long day, plus the fact that lunch and drinks are not included.

The water around Kerama National Park can be remarkably clear, with turtles, colorful reef fish, small caves, and even the occasional reef shark. I also like that SEAKERS limits each group to four people, though some sites and the boat may still feel busy when several operators gather in the same area.

Kerama Islands at a glance

• Small groups capped at four participants: This helps the guide keep track of everyone and gives the day a calmer, more personal feel.
• Two boat descents included: You get the core experience without needing to pay extra for the optional third descent.
• A third descent costs 5,500 yen: Bring cash if you want more time underwater.
• Pickup and drop-off are included: Service covers selected areas of Naha, Urasoe, and Ginowan.
• English and Japanese instruction: The boat and safety briefings are designed to be clear before you enter the water.
• Free underwater photos: Guides may send photos and short videos afterward, a useful souvenir from the day.

Why this trip is worth considering

Kerama National Park is the reason to book this outing. The islands are reached by boat from Okinawa’s main island, and the time on the water opens access to reefs and coastal sites that you cannot reach from shore.

The strongest part of the experience is the combination of scenery and organization. You are not simply handed equipment and sent toward the water. The morning includes a boat briefing, gear assembly, transport, two scheduled descents, lunch, and the option of a third descent. That structure matters when you are spending $206 and giving up most of a day.

The small group is another real advantage. A maximum of four participants gives the guide room to watch air use, comfort, and pace. Ryuta received especially strong praise for being patient and attentive, while Yun was described as clear, friendly, and easy to understand in English.

Still, this is not a private charter. One person found the boat and reef busier than expected, particularly compared with less crowded underwater locations. If you want complete solitude, Kerama may not deliver it on every day.

The 6:45 AM pickup from Naha

The day begins early, with pickup around 6:45 AM. SEAKERS provides transport from selected accommodations in Naha, Urasoe, and Ginowan, then returns you to the same general area in the afternoon.

The service is complimentary in much of Naha, but there are limits. Akamine and the Shuri area are excluded. In Ginowan, pickup is limited to Laguna Garden Hotel, Okinawa Prince Hotel, and Moon Ocean Ginowan Hotel & Residence. If you are outside the covered zones, ask before booking.

You should wait outside your accommodation entrance and be ready at the stated time. This is not a flexible hop-on arrangement. Arriving late can mean being treated as a no-show, so set an alarm and keep your morning simple.

Airbnb pickup requires extra care. You need to give a precise location on the registration form sent after booking. A vague address can create an avoidable problem before an already early start.

The transportation service earned a perfect score from all recorded ratings, and that makes sense as a practical benefit. A hotel pickup removes the need to find a marina before sunrise, rent a car, or work out local parking.

The 45-minute briefing and gear setup

At about 7:00 AM, you receive the boat briefing and assemble your scuba equipment. The safety explanation is listed as 45 minutes, not 45 hours as one itinerary entry accidentally suggests.

This is the point where you should speak up about anything that affects comfort or safety. Confirm your wetsuit size, especially if standard suits often feel tight around your shoulders or chest. One woman found that her rented suit was too small to zip properly, although the warm water made it manageable. Asking for a larger size at the start is wiser than trying to tolerate a poor fit all day.

Full equipment rental is included, which adds useful value to the $206 price. You do not need to pack your own regulator, tank, or standard scuba kit. You do need to bring your certification, a towel, change of clothes, flip-flops, food, and drinks.

A dive computer is not included. It costs 1,500 yen in cash, or it may be provided free in exchange for a positive review. I would treat the computer fee as part of your budget rather than assume the free option. A review should reflect your honest experience, not function as payment.

The speedboat ride to Kerama

The boat leaves around 7:45 AM, with the trip to the islands taking roughly an hour. This is more than a transfer. It is a useful transition from Naha’s urban waterfront to the open sea and the national park.

The boat is described as a hardboat, with an organized system for setting up equipment. That matters because cramped, disordered gear areas can make the first hour stressful. Here, the preparation is intended to be systematic, giving you time to check your kit before reaching the first site.

Seasickness deserves serious thought. The operator does not recommend this activity for people prone to motion sickness. You will spend about two hours on the boat before the first descent, then return by boat in the afternoon. If you know that open-water trips are difficult for you, this may not be the best choice.

Oversize luggage and large bags are not allowed. Bring only what you need for the day, and keep your belongings compact.

Two morning descents in Kerama National Park

The first descent is scheduled around 9:00 AM, followed by the second at about 10:30 AM. Together, the two sessions provide the main value of the outing.

Kerama’s underwater appeal comes from visibility, coral, and marine life. Specific sites mentioned by one participant included Nosaki, Doma, and Kameku. Conditions vary, but the clearest days can offer blue water and long sightlines across the reef.

You might encounter sea turtles, fluorescent-looking reef fish, schools of small fish, and reef sharks. One participant described watching a reef shark swim nearby, while another saw turtles and large trevally moving around a school of smaller fish. These encounters are never guaranteed, but they show the range of life found around the islands.

The guides also appear to make safety a priority. Ryuta was praised for helping newer or nervous participants feel relaxed, and another account described the guide as attentive throughout the day. That is especially valuable if you have certification but limited recent experience.

Remember that certification is required. This is not a lesson for beginners or a first-time introductory session. You must hold a valid qualification from a recognized organization.

The group limit of four helps, but you should not confuse it with a private experience. The boat may carry other groups, and popular reef sites can have several operators nearby. Your time underwater may feel personal even when the broader setting is shared.

Lunch on the boat, with planning required

Lunch is scheduled around 11:30 AM, between the second and optional third sessions. Lunch is not included, so you need to bring a packed meal along with drinks.

This sounds minor, but it is one of the easiest details to miss when booking. After two demanding sessions and a boat ride, you will want something substantial. Pack food that is easy to eat on a moving boat, and bring enough water for the entire day.

Towels are also not supplied. A change of clothes becomes useful after the final session, particularly if you do not want to sit in a damp swimsuit during the ride back.

The lunch break gives you time to rest, eat, and decide if you want the extra descent. You do not have to commit to three sessions from the start.

The optional third descent for 5,500 yen

At around 12:30 PM, you can add a third descent for 5,500 yen in cash. Several people chose it and considered the extra time worthwhile, especially when the first two sessions were clear and full of marine life.

The optional session can also make the day more tiring. You are already awake early, have traveled by boat, and completed two underwater sessions. If you are cold, tired, or low on energy, stopping after two is a sensible choice.

I like the flexibility here. The base price includes two sessions, so you are not paying for an extra activity you may not want. At the same time, enthusiastic certified participants can make the most of the boat trip with a third session.

Bring the cash in advance. The optional fee is not presented as a card payment, and the same applies to the computer rental.

Underwater photos from the guides

Free underwater photos and videos are one of the nicest extras. A guide may photograph you and the marine life, then send edited images or short clips after the outing.

This adds value in two ways. First, you can concentrate on your buoyancy and surroundings instead of trying to manage a camera. Second, you get a record of the day without buying a separate photo package.

The results depend on water conditions, available light, and what the guide encounters. Still, the personal footage can be more useful than a generic souvenir because it shows you in the actual Kerama sites.

Treat marine life with care. Touching animals or coral is not allowed. The rule protects the environment and also keeps encounters respectful. Do not chase turtles, handle fish, or reach toward anything simply to improve a photograph.

Returning to Naha around 2:30 PM

The boat returns to port at about 2:30 PM, followed by accommodation drop-off around 3:30 PM. Timing can shift with weather, sea conditions, and the chosen sites.

That makes this a full-day commitment. You should not schedule a tight afternoon appointment, domestic flight, or important dinner reservation immediately afterward. The return time is an estimate, not a guarantee.

Bad weather or a canceled boat does not automatically end the day. SEAKERS may arrange an alternative site at no additional cost. If no suitable option is available, a full refund is issued. This is a useful safeguard in Okinawa, where sea conditions can alter plans.

What the $206 price really covers

At $206 per person, this is not a bargain-basement harbor outing. But the price includes several costly pieces: round-trip boat transport, two sessions in Kerama National Park, all standard scuba equipment, an English or Japanese guide, insurance, accommodation transport, and underwater photos.

The boat ride alone is important. You are paying to reach the Kerama Islands rather than staying near Naha, and the national park setting is the main attraction.

The value is strongest if you need equipment rental and transport. A certified participant with personal gear and access to a boat may find the price less compelling, but most visitors would otherwise need to arrange several services separately.

Budget extra for lunch, drinks, a towel if needed, the 1,500-yen computer rental, and the 5,500-yen optional third session. If you choose all the extras, the final cost rises, though three sessions and photo coverage can make the day feel much fuller.

Who should book this experience

I would recommend it most strongly to certified divers who want a guided day trip from Naha without arranging transport, tanks, and a boat independently.

It suits you if:

• You hold a recognized scuba certification.
• You want English-language support.
• You prefer a group limited to four people.
• You are comfortable spending a full day on a boat.
• You want reef scenery, turtles, fish, and the possibility of larger marine life.
• You value included photos and hotel pickup.
• You are willing to pack lunch and carry cash for extras.

This is not suitable for non-swimmers, uncertified participants, children under 12, pregnant women, wheelchair users, or people with several listed medical conditions, including heart problems, epilepsy, diabetes, kidney problems, high blood pressure, or recent surgery. The operator also excludes people over 60 and those with low fitness, so check the restrictions carefully before paying.

Practical tips for a smoother day

Pack light and keep your bag small. Large luggage is not allowed, and you will have limited need for anything beyond clothing, food, drinks, and personal essentials.

Ask for your wetsuit size before leaving the port. A suit that is too tight can distract you all day, even in warm water.

Bring cash in Japanese yen. You may need 5,500 yen for the third session and 1,500 yen for the computer. Lunch and drinks also need to be handled separately.

Give exact accommodation details, especially for an Airbnb. Then wait outside at the pickup point and arrive early.

If you want three sessions, say so when discussing the schedule, but make the final call after lunch. The optional session is a choice, not an obligation.

Finally, protect the marine life. Look, enjoy, and keep your hands to yourself. Good underwater manners are part of being a responsible certified diver.

Should you book the SEAKERS Kerama trip?

Book it if you want a well-organized route from Naha to some of Okinawa’s clearest underwater sites, with equipment, transport, insurance, and English support already arranged. The small group, careful guides, and free photos make the $206 price reasonable for visitors who need a complete package.

Think twice if you dislike early starts, boat travel, shared sites, or carrying your own lunch. Also check the medical and age restrictions carefully. For a certified diver who wants two strong sessions with the option of a third, SEAKERS offers a practical and well-supported day in Kerama National Park.
