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

Kerama National Park is the main event here: clear blue water, colorful coral, turtles, reef fish, and the chance to visit several sites in one long day from Naha. Small groups of up to four keep the pace personal, while guides such as Ryuta and Yun explain the boat and underwater procedures in English.

I like the included hotel transport and equipment, which removes much of the usual Okinawa logistics. I also like the free underwater photos, a useful extra when your hands are busy with gauges and your camera stays dry. The main consideration is the early start, the long boat ride, and the fact that lunch and drinks are not included.

Kerama National Park in one long day

• Three possible underwater stops: Two are included, and a third can be added for 5,500 yen in cash.
• Small groups: The maximum is four participants, a good setup for safety and individual attention.
• Clear, warm Okinawan water: Recent trips included turtles, reef sharks, fluorescent fish, coral, and very good visibility.
• English and Japanese support: Boat and safety briefings are provided in English or Japanese.
• Photos included: The guide sends underwater photos and videos after the outing.
• Transport from selected areas: Pick-up and return are available in Naha, Urasoe, and limited parts of Ginowan.

An early start from Naha

The day begins around 6:45 a.m., when you meet the vehicle outside your accommodation. This is a proper early start, not a sleep-in activity, so set out your clothes and certification the night before.

Transport is offered in Naha, Urasoe, and selected parts of Ginowan. Naha coverage excludes the Akamine and Shuri areas. In Ginowan, pick-up is limited to Laguna Garden Hotel, Okinawa Prince Hotel, and Moon Ocean Ginowan Hotel & Residence. Give precise accommodation details when booking, especially if you are staying in an Airbnb.

You need to be outside at the agreed time. The operator treats a late arrival at the meeting point as a no-show, so this is not the morning to wander down for a last-minute coffee.

The ride is one of the most useful parts of the package. You do not need to arrange a taxi before sunrise, find the harbor, or haul scuba equipment through town. Pick-up times can vary by location, and the return to your accommodation is generally around 3:30 p.m., though weather and sea conditions can shift the schedule.

The 45-minute briefing and boat preparation

At about 7 a.m., you receive the boat briefing and assemble your equipment. The supplied schedule describes this as a 45-minute safety briefing, followed by preparation for departure.

This is where the small-group format matters. With no more than four participants, the guide can check equipment, answer questions, and make sure everyone understands the plan without turning the morning into a crowded classroom. English-speaking instructors handle the boat and underwater briefings, and Japanese guidance is also available.

You must hold a valid certification from a recognized organization. Bring proof of certification, along with a change of clothes, towel, flip-flops, food, drinks, and packed lunch. Equipment rental is included, but a dive computer costs 1,500 yen in cash unless it is provided under the operator’s positive-review arrangement. I would budget for the rental rather than count on that offer.

One practical equipment note comes from a past participant who found the women’s wetsuit too tight across the bust. If you need a larger size or a particular fit, ask early. A wetsuit that fits poorly can distract you before you even reach the first site.

The one-hour speedboat ride to the islands

The boat leaves at roughly 7:45 a.m. and takes about an hour to reach the Kerama Islands. The ride is part of the appeal, but it is also the portion most likely to test anyone prone to seasickness.

Bring only what you need. Oversize luggage and large bags are not allowed, and space on a working dive boat is best kept clear. Pack a small, secure bag with dry clothes, sun protection if needed, water, and lunch. Towel and drinks are not supplied.

The boat is described as a hardboat, with a systematic equipment setup. You should expect a practical working vessel rather than a sightseeing cruise. That is fine for most certified divers, but the boat ride, early hour, and repeated climbs in and out of the water make this a better choice for people with a reasonable fitness level.

Two included descents in Kerama National Park

The first underwater session is planned for around 9 a.m., with the second at approximately 10:30 a.m. Together, the included sessions take about two hours, though exact timings depend on the site and sea conditions.

Kerama National Park is prized for its clear water and abundant marine life. Recent outings included turtles, colorful coral, fluorescent fish, reef sharks, small caves, and large trevally moving around schools of smaller fish. You might see some of these creatures, but marine life is never guaranteed, and the exact sites change with conditions.

One outing visited Nosaki, Doma, and Kameku. Another included three different locations, which made the extra session feel worthwhile. Visiting separate sites gives you more variety than spending the whole morning in one area, though the boat and reefs can be busy with other operators during popular periods.

The guide’s role is a major part of the experience. Ryuta is named repeatedly in the supplied feedback, with participants appreciating his calm instruction, careful attention, and friendly manner. Yun was also praised for clear English and a well-organized approach, while another guide was recorded as Utah, though the spelling may be uncertain. The common thread is close supervision and a relaxed pace.

For certified participants, this is not a beginner lesson. You should be comfortable with your certification skills and ready to follow the guide’s safety procedures. The small group helps, but it does not replace your own responsibility for buoyancy, air checks, and equipment awareness.

The optional third session for 5,500 yen

After the first two sessions, you return to the boat for lunch. The schedule allows an optional third underwater session around 12:30 p.m., at an extra cost of 5,500 yen paid in cash.

If the water is clear and you still have energy, this is an attractive add-on. Several people chose three sessions and visited three sites, with turtles, a reef shark, coral, fish, and small caves adding variety to the day. The extra time in the water also makes the long journey from Naha feel more worthwhile.

The extra session is not included in the advertised price, so decide with your budget and stamina in mind. You should also bring enough food and water for the longer day. Lunch is not provided, and the schedule gives you time to eat on the boat rather than at a restaurant on shore.

Lunch on board, with no meal included

The boat lunch stop is simple and practical. You eat on board at about 11:30 a.m., with another break before the optional third session.

Pack food that is easy to manage on a boat. Drinks are also your responsibility. There is no supplied towel, so bring one for the ride home, especially if you prefer not to sit in wet gear.

This arrangement keeps the day focused on the water and avoids losing time returning to shore. The trade-off is that you need to plan ahead. Do not assume you can buy lunch after pick-up, and do not forget water.

Free photos and the value of the package

The price is about $206 per person. That is not a budget half-day activity, but the package includes hotel transport, boat travel, equipment, two boat-based underwater sessions, an English or Japanese guide, insurance, and underwater photos.

The photos add real value. Guides such as Ryuta have sent photos and short videos after the outing, allowing you to remember turtles, coral, fish, and the general color of the water without carrying a camera. Photo quality and quantity can vary, but the service is a welcome extra rather than a fee you must add at the end.

The package makes the most financial sense if you need equipment and transport. If you already have all your own gear and are staying near the port, compare prices carefully. For visitors staying around Naha, the included transfers and rental gear reduce the number of separate costs to arrange.

The third session changes the calculation. Add 5,500 yen in cash if you want three sessions, and set aside 1,500 yen in cash for a dive computer if you need one. Bring Japanese yen for both possibilities.

Who should book this Kerama outing

I would choose this for a certified diver who wants a full day at several Kerama sites without organizing a boat, rental shop, transfers, and guide separately. It suits solo participants and pairs particularly well because the four-person limit can make the day feel personal.

It is also a good fit if English support matters. You receive the boat and safety briefings in English, and the guides have experience working in the international scuba industry. The reported encounters with turtles, reef sharks, coral, and schooling fish give the day plenty of appeal, but you should come for the quality of the setting rather than promise yourself a specific animal.

This is not suitable for uncertified participants, non-swimmers, children under 12, pregnant people, wheelchair users, or people with several listed medical concerns, including heart problems, epilepsy, diabetes, kidney problems, high blood pressure, recent surgery, or low fitness. People prone to seasickness should think carefully about the one-hour boat ride each way.

The age guidance also excludes people over 60. If you have a medical condition or are unsure about your fitness, ask the operator before booking rather than relying on a general assumption.

Weather changes and cancellation flexibility

The Kerama sea can change the plan. If bad weather, a boat cancellation, or another unforeseen problem prevents the scheduled outing, the operator may arrange another site at no extra cost. If no suitable option is available, a full refund is issued.

You can cancel up to 24 hours before the activity for a full refund, and the reserve-now, pay-later option lets you hold a place without paying immediately. These terms are useful when Okinawa weather is uncertain, though they do not remove the need to check the forecast and pack sensibly.

The schedule is also an estimate. Pick-up, departure, site order, and return time can move with sea conditions, boat operations, and the needs of the group. Keep the rest of your afternoon flexible.

My practical verdict

SEAKERS offers a well-organized full-day trip with the right ingredients for certified divers: a small group, English-speaking guidance, equipment rental, transport from selected areas, insurance, and a strong chance of clear water and marine life in Kerama National Park.

I especially like the combination of two included sessions and a clearly priced third option. You can keep the basic day reasonable, then decide on the boat if conditions and energy are good. The main drawbacks are the early departure, one-hour boat ride, packed lunch requirement, limited pick-up zones, and extra cash costs.

Book this if you want convenience and personal guidance more than the lowest possible price. Ask about wetsuit sizing, confirm your pick-up point, bring proof of certification, and carry food, drinks, towel, and cash. If you do that, this is a strong choice for a serious Okinawa day on the water.
