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

The big draw here is the Kerama National Park, reached by boat from Naha in about an hour. Expect clear water, coral, turtles, colorful fish, and the chance to visit several sites in one day. I like the small groups, limited to four people, and the practical hotel pickup and drop-off. I also like that underwater photos are included.

The main consideration is the boat. Conditions and crowding can vary, and one participant found the boat and reef busier than expected. You must already hold a recognized scuba certificate, and the optional third session costs extra.

Key details before you book

• Three possible pickup areas: Pickup and drop-off are offered in Naha, Urasoe, and selected parts of Ginowan.
• Two sessions included: The $206 price covers two boat-based scuba sessions in Kerama National Park.
• Third session available: Add a third session for 5,500 yen in cash if conditions, time, and energy allow.
• Small group format: The group is limited to four participants, useful for safety and individual attention.
• English and Japanese instruction: Guides give boat and safety briefings in English or Japanese.
• Photos included: SEAKERS sends underwater photos and videos after the outing.

Why Kerama National Park is worth the boat ride

Okinawa has plenty of water activities close to shore, but the Kerama Islands offer a stronger reason to spend a full day at sea. The trip takes you away from Naha and into a protected marine area known for clear water, coral, and abundant sea life.

The boat ride takes roughly one hour each way. That sounds long if you are hoping for a quick morning activity, but it is a fair trade for access to several sites around the islands. Recent outings have included Nosaki, Doma, and Kameku, with each location offering a different setting.

You might see sea turtles, reef sharks, schools of small fish, coral formations, and brightly colored reef fish. One outing also included a close look at a reef shark, while another produced sightings of turtles and large trevally moving around a school of smaller fish. These sightings are never guaranteed, but the park gives you a good chance to encounter varied marine life in one day.

The clearest conditions tend to make the biggest impression. Several participants described the water as exceptionally clear, with strong visibility and blue water extending across the reef sites. Visibility still depends on weather, current, and the day’s assigned locations, so treat those conditions as a benefit, not a promise.

An early start that keeps the day moving

Pickup begins around 6:45 a.m. You wait outside your accommodation entrance, so be ready a few minutes early. The operator is strict about timing and can treat a late arrival as a no-show. That is not unusual for a boat trip, since the vessel cannot hold its schedule for one missing participant.

Pickup is available in Naha, Urasoe, and limited parts of Ginowan. In Naha, the Akamine and Shuri areas are excluded. In Ginowan, pickup is limited to Laguna Garden Hotel, Okinawa Prince Hotel, and Moon Ocean Ginowan Hotel & Residence.

If you are staying in an Airbnb, provide clear accommodation details on the registration form sent after booking. This is especially important because the meeting point may not be as obvious as a hotel lobby.

At about 7:00 a.m., you receive the boat briefing and assemble your equipment. This early setup helps the morning run smoothly, but it also means you should not arrive expecting a leisurely breakfast before departure. Bring food, drinks, and a packed lunch. Lunch is not included.

The boat ride from Naha to the islands

The boat leaves at about 7:45 a.m. and reaches the Kerama area around 9:00 a.m. The transfer is part of the experience, but it is also the time when seasickness can become an issue. The activity is not suitable for people prone to seasickness, and the operator does not list oversized luggage or large bags as allowed items.

The boat is described as a hardboat, with gear setup handled in an organized manner. You will need to work within the available space, so pack lightly. A change of clothes, towel, flip-flops, food, and drinks are useful. Keep your bag compact and leave large luggage at your accommodation.

Boat conditions can change with the weather. If the planned sites are not usable, SEAKERS may arrange another site at no extra cost. If no suitable alternative is available, the outing can be canceled with a full refund. This gives you some protection, but it cannot guarantee calm seas or a particular animal sighting.

Two included sessions in protected waters

The first underwater session begins at about 9:00 a.m., followed by the second around 10:30 a.m. Together, the two sessions occupy roughly two hours, with time between them for returning to the boat, checking equipment, and preparing again.

This schedule suits certified divers who want a full day without rushing from site to site. You receive a clear boat briefing and a session briefing from an English-speaking or Japanese-speaking guide. The small-group limit of four means the guide can keep a closer eye on the group than on a large charter.

Guides such as Ryuta, Yun, and Utah have received strong praise for calm instruction, clear explanations, and attention to safety. Ryuta has been described as patient and attentive, while Yun’s English was considered understandable and helpful. Those details matter if you are comfortable underwater but prefer straightforward communication before entering the water.

The marine life is the main reward. You may find turtles moving across the reef, schools of small fish, fluorescent-colored reef fish, and occasional larger animals. Coral sites can include small caves, depending on the location and conditions. You should not expect every trip to produce the same animals or visibility, but the range of sites helps keep the day interesting.

One useful point: this is for certified divers, not beginners. The operator requires a valid qualification from a recognized organization. You should also be comfortable managing your own equipment and following boat and safety instructions.

Lunch on the boat, with no surprise catering

Lunch is scheduled around 11:30 a.m. The price does not include food or drinks, so bring a packed meal. This arrangement gives you control over what you eat, but it means you need to prepare before pickup.

A boat lunch is usually about convenience rather than comfort. Bring food that is easy to handle, along with enough water for the full eight-hour day. A towel and dry change of clothes will also make the return trip more pleasant.

The surface interval gives you a chance to rest before deciding on the optional third session. Do not treat the extra session as automatic. Your guide will consider the conditions, the schedule, and your readiness.

Is the optional third session worth 5,500 yen?

The third session begins around 12:30 p.m. and costs 5,500 yen in cash. It is not included in the $206 base price, so budget for it separately if you want the full day underwater.

For an experienced certified diver, the add-on can be good value. The boat is already in the Kerama area, the equipment is already set up, and the trip back to Naha is still ahead. Several participants chose the third session and visited three different sites in one day.

The extra cost is less appealing if you are tired, feeling seasick, or mainly interested in a relaxed introduction to the area. Two sessions already make this a substantial day. You can decide after the first two rather than committing in advance.

Bring cash for the add-on. The same applies to the optional dive computer, which costs 1,500 yen in cash. The computer is free if you leave a positive review, according to the booking details. If you prefer to use a computer, confirm the arrangement before leaving the port so there is no confusion.

Equipment, safety, and underwater photographs

Full scuba equipment rental is included. That removes one of the larger extra costs attached to an offshore trip. Dive insurance is also included, and the guide handles the boat and safety briefings.

Fit matters. One participant found a hired wetsuit too small, particularly around the chest, even though it could still be worn. If you need a larger size or have a particular fit concern, state it clearly when you register. Do not assume a standard rental size will work for everyone.

Underwater photos are included, which adds real value at this price. The guides take photos and videos during the day, then send them afterward. That gives you a record of turtles, coral, fish, and the sites you visited without needing to carry your own camera.

You are expected not to touch marine life. This is both a safety rule and a basic protection measure for the reef. Listen closely to the briefing, keep your hands off coral and animals, and follow the guide’s instructions about spacing and movement.

What the $206 price really covers

At $206 per person, this is not a cheap half-day activity. It is an eight-hour boat trip with hotel transportation, two offshore scuba sessions, equipment rental, insurance, a professional guide, and underwater photos.

The value improves if you use the included pickup and need to rent equipment. A separate boat transfer, gear rental, and photo package could quickly push up the cost of an independent arrangement. The small group also matters. With no more than four participants, you are paying for a more personal setup than a large charter can usually provide.

The price is less attractive if you already own all your equipment, have your own transport, and want only one short session. In that case, a closer shore-based option might suit you better. For a full Kerama day from Naha, the package is fairly strong, especially when the photos and insurance are included.

Who should book this trip

I would choose this outing if you are a certified diver staying in or near Naha and want access to Kerama National Park without arranging your own boat. It is also a good match if you value English-language support, hotel transport, and a small group.

The trip is not suitable for non-swimmers, uncertified divers, children under 12, pregnant people, or anyone with several listed medical concerns, including heart problems, epilepsy, diabetes, kidney problems, high blood pressure, or recent surgery. The activity also excludes wheelchair users and people with low fitness.

The age guidance lists people over 60 as not suitable. If that applies to you, check directly with SEAKERS before booking rather than assuming your experience level is enough.

Practical preparation for the morning

Pack a towel, dry clothing, flip-flops, food, drinks, and proof of scuba certification. Keep your luggage small. Your accommodation should be the base for large bags.

Wear or bring swimwear under your clothes, and make sure you have enough time to eat before pickup. The day starts early, and the boat schedule is fixed.

If wetsuit sizing is important for you, ask for the right size in advance. Also decide if you want to pay for the optional third session and dive computer in cash. You can still make the final call about the third session after the first two.

Free cancellation is available up to 24 hours before the activity, and reserve-now-pay-later booking is offered. Weather can alter the route, but the operator may substitute another site or issue a full refund if no suitable plan is possible.

Should you book the SEAKERS Kerama trip?

Book it if you want a full day on the water, strong visibility when conditions cooperate, several reef sites, and a small group with English-speaking support. The combination of transportation, gear, insurance, two sessions, and underwater photos makes the $206 fee reasonable for visitors based in Naha.

Think twice if you dislike early starts, boat travel, or carrying your own lunch. Also remember that the third session, dive computer, and food cost extra. For certified divers who want Kerama’s reefs without handling the logistics themselves, this is a well-focused choice. The best reason to go is not the promise of one specific animal, but the chance to spend a full day visiting protected sites with a guide who keeps the schedule and safety details under control.
