Okinawa:Kerama Islands experience Diving/Snorkeling/WhaleWatching
The sea here does the talking. This seven-hour outing from Naha takes you by boat toward the Kerama Islands, with two or three underwater stops near islands such as Zamami, Tokashiki, Kuroshima, and Maejima. You can choose introductory scuba, snorkeling, or simply stay with snorkeling while others in your group try scuba.
I like the beginner-friendly instruction and the chance to visit several locations in one day. Hotel pickup within Naha, equipment, boat fare, insurance, drinks, and requested seasickness medicine are included, which makes the $96.67 price look strong. The main caution is that the experience depends heavily on weather and sea conditions, and one serious complaint involved faulty scuba equipment and slow attention to an emergency.
The tour is designed for people without a scuba license, and staff provide land instruction, equipment guidance, and practice at the surface. Still, you should read the health checklist carefully before booking. A medical condition can prevent participation, and there is no refund if you fail the health check on the day.
Key Points Before You Book
- Two or three Kerama locations: The boat may visit Zamami, Tokashiki, Kuroshima, and Maejima, with the exact stops shaped by sea conditions.
- Scuba without a license: Introductory scuba is available for beginners, including people who are nervous in the water or cannot swim confidently.
- Snorkeling and scuba on one boat: Couples and groups can choose different activities while staying together for the day.
- Whale season runs January 12 through March 31: Sightings are possible, but never guaranteed, and the tour may change or be canceled in poor conditions.
- Useful extras are included: Pickup in Naha, snorkeling and scuba equipment, insurance, ship fare, tea, water, and seasickness medicine on request.
- A mixed safety picture: Most feedback praises the attentive instructors, but one account raises a serious concern about equipment inspection and emergency response.
Leaving Naha for the Kerama Islands
The day begins at 7:30 a.m. at Miegusuku Port, also written as Miegusuku Port, 3-chōme-20 Nishi, Naha. The activity ends back at the same port, making it easy to plan around a Naha hotel or a later evening in the city.
Pickup is offered within Naha, but it is not guaranteed if the shuttle bus is full. I would confirm pickup as soon as you book and keep the port address handy. An early start matters here: the outing lasts about seven hours, so returning to the city still leaves part of the evening free.
The group can include up to 15 people. That is small enough for a more personal feel than a large sightseeing boat, but it is not a private charter. You may share the boat with beginners, snorkelers, certified scuba participants, and people who choose to remain above the water.
The boat ride itself is part of the attraction. The Kerama Islands are known for clear water, coral, and abundant fish, but conditions can change quickly. Wind, waves, and visibility determine both comfort and the choice of stops. If you are prone to seasickness, request the free medication when booking rather than waiting until the morning of departure.

What Happens Before You Enter the Water

The introductory scuba format is built around reassurance. Staff explain the activity on land, go over the equipment, and provide practice at the surface before taking you farther from the boat. The stated plan includes three explanation points: on land, before entering the water, and at the surface.
That approach is especially useful if you are trying scuba for the first time. Several comments describe instructors staying close, checking that beginners were comfortable, and making nervous participants feel safe. Takashi receives particular praise as an instructor, with one first-time participant calling him excellent.
You do not need a scuba license for the introductory session. The staff also say that people who cannot swim can participate, though you must be in suitable health and able to follow the instructor’s directions. A wetsuit or life jacket is required for safety, and floating rings are available.
This is not a casual jump-overboard activity. You should expect instructions, equipment fitting, surface practice, and close supervision. That is good news for first-timers, though it may feel slow if you already have substantial scuba experience and want a more independent underwater session.
Zamami, Tokashiki, Kuroshima, and Maejima

The route may include two or three carefully selected sites around the Kerama Islands. The operators name Zamami Island, Tokashiki Island, Kuroshima Island, and Maejima Island as possible areas, but they do not promise a fixed order or a particular island.
That flexibility is practical. The crew can choose locations according to the day’s sea conditions rather than forcing the same route every time. You may see coral gardens, schools of colorful fish, and, with luck, sea turtles. A few people also reported seeing a baby shark.
The biggest reward is variety. One stop may suit beginner scuba, another may work better for snorkeling, and a third may offer the best chance of seeing turtles or reef fish. The exact underwater scenery is never guaranteed, so you should book this for the overall day on the Kerama sea, not for one specific animal.
Sea turtles are a central part of the appeal, but the operator clearly warns that sightings may not happen. That warning is worth taking seriously. Ocean wildlife follows its own timetable, and no guide can promise a turtle, shark, or whale on demand.
The same applies to visibility. The description presents water clear enough to see the seabed, but weather and sea conditions can affect what you actually see. If you get calm water and good visibility, the coral and fish should be the highlight. If conditions turn rough, the crew may alter the route or cancel the outing.
Choosing Scuba, Snorkeling, or Both

The setup works well for mixed groups. You can try introductory scuba while a partner or friend snorkels, then compare what you saw when everyone returns to the boat. One couple enjoyed being able to choose different activities without splitting up their group.
For a first scuba experience, the main benefit is access. You get to experience the underwater environment without first completing a certification course. The instruction is intended to be gentle and unhurried, which is exactly what a nervous beginner needs.
Snorkeling is not an inferior backup here. The water is described as clear, and the reefs and fish can be viewed from the surface. One person who chose snorkeling felt well protected and saw turtles, many kinds of fish, and sharks. If you are uncomfortable breathing through a regulator, snorkeling lets you enjoy the same general setting with less equipment and less pressure.
You can also use a floating ring if needed. That matters for children and adults who are uneasy in open water, although the tour still requires a health check and basic cooperation with the crew.
The safety record presented in the feedback is mixed. Most comments describe attentive instructors and a safe feeling in the water. One serious report says a participant received a broken regulator, began taking in water, and struggled to get the driver’s attention while the boat was moving quickly. The operator responded that equipment would be checked. I would treat this as an important reminder to inspect your regulator before entering the water and signal immediately if anything feels wrong.

Whale Watching From January 12 Through March 31

During the seasonal period from January 12 through March 31, whale watching is included. This adds another reason to consider the trip in winter and early spring, especially if you like the idea of combining reef time with a chance to see large marine life from the boat.
The wording is careful: whales may not appear, and poor weather or sea conditions can affect the outing. Do not book this as a guaranteed whale-watching cruise. Think of it as a Kerama marine day with whale watching added when the season and conditions allow.
The seasonal change may also affect the feel of the day. Cooler months can be more comfortable on the boat, but you should still expect to wear a wetsuit or use a life jacket for water activities. Ask the operator about current conditions if you are choosing between dates.
Photos, Drinks, Snacks, and Lunch

You receive two or three underwater photos as a gift, available for download through Facebook. A full-HD video service is also available, though the supplied information does not state whether that service costs extra. Ask before departure if the video matters to you.
Tea and water are included. Children under 12 receive free snacks, and shaved ice is offered at no charge in August and September. Eating shaved ice while looking over the Okinawan sea sounds like a small touch, but it can be welcome after time in the water.
Lunch is not included in the listed price. One account refers to a curry lunch, but because the official inclusions exclude lunch, you should confirm the arrangement before relying on a meal being provided. Bring your own food or money for lunch unless the operator gives you different instructions.
This is one area where the low price needs a little interpretation. At $96.67 per person, the package includes the boat, insurance, equipment, water activities, and Naha pickup. Once you add the cost of renting scuba and snorkeling gear separately, the value improves. Just remember to budget for lunch and any optional video service.
Who Will Get the Most From This Outing

This experience suits a first-time scuba participant who wants a gentle introduction rather than a full certification course. It also works for families and groups with mixed interests, since some people can snorkel while others try scuba from the same boat.
It is a good fit if you want:
- A full morning and afternoon on the Kerama sea
- Beginner instruction and surface practice
- Several possible reef locations
- A chance to see turtles, fish, or small sharks
- Naha pickup and a package price under $100
- Seasonal whale watching from January through March
It may not suit you if you need a fixed itinerary, guaranteed wildlife, a quiet private boat, or highly technical scuba instruction. The route changes with the sea, and the group may include up to 15 people.
Health rules are strict. Conditions that can lead to refusal include asthma or wheezing, chronic sinus problems, epilepsy, serious lung or heart conditions, diabetes, recent surgery, certain ear problems, pregnancy, and recent alcohol use. The checklist sent after booking matters. If you are unsure about a medical issue, ask before paying because failure to pass the health check on the day does not qualify for a refund.
Cancellations and Weather Rules

You can cancel up to 24 hours before the start time for a full refund. Changes made less than 24 hours before departure are not accepted, and late cancellations are not refunded.
Weather is the main exception. If the operator cancels because conditions are poor, you can receive a different date or a full refund. Since the sea determines the route and sometimes the entire outing, keep some flexibility in your Okinawa schedule.
FAQ
Where does the tour start?
It starts at 7:30 a.m. at Miegusuku Port, 3-chōme-20 Nishi, Naha, Okinawa 900-0036, Japan. The activity returns to the same meeting point.
Is pickup available from my Naha hotel?
Pickup is offered within Naha, but it may not be available if the shuttle bus is full. Confirm the pickup details after booking.
Do I need a scuba license?
No. The introductory scuba option is designed for people without a license and includes verbal instruction, equipment guidance, and surface practice.
Can I participate if I cannot swim?
The operator says that people who cannot swim can participate. Wetsuits, life jackets, and floating rings are available, but you must still meet the health requirements and follow staff instructions.
Are whale sightings guaranteed?
No. Whale watching is included from January 12 through March 31, but whales may not appear. Weather and sea conditions can also affect the activity.
Is lunch included?
No. Lunch is not included in the listed price. Tea and water are included, and snacks are free for children under 12.
What happens if bad weather cancels the tour?
You will be offered another date or a full refund if the activity is canceled because of poor weather. You can also cancel for a full refund up to 24 hours before the start time.
Should You Book the Kerama Islands Experience?
I would book this if you want an affordable first taste of Okinawa’s underwater world and value a flexible day that works for both scuba beginners and snorkelers. The strongest points are the friendly instruction, several possible Kerama locations, Naha pickup, and a price that covers most of the costly equipment and boat elements.
I would book with two checks in mind. First, read the medical questionnaire carefully and ask about any condition before committing. Second, confirm the safety briefing and inspect your equipment before entering the water. If you accept changing conditions and understand that turtles and whales are possibilities rather than promises, this is a practical way to spend a full day on the Kerama sea.
