Okinawa: Naha: 1 day Kerama Islands diving license required

Introduction

Our review explores a popular one-day tour in Okinawa that takes certified divers to the stunning Kerama Islands. If you’re looking for an active, memorable day filled with underwater adventures, whale watching, and authentic Okinawan hospitality, this tour might be just what you need.

What we especially like about this experience is its flexibility—whether you’re solo or part of a group, the guides respond to your level and interests. Plus, the inclusion of whale watching from January to March adds a special seasonal touch.

However, a key consideration is that divers must have a certification (C-card)—so this isn’t suitable for complete beginners or non-swimmers. Also, the tour can be busy with mixed groups, which might affect the quiet, relaxed vibe some travelers seek.

This tour is perfect for seasoned divers eager to explore Okinawa’s vibrant marine environment or those wanting a comprehensive day out that combines adventure, nature, and local culture.

An In-Depth Look at the Tour Experience

Transportation and Group Size

The tour begins with door-to-door transport from your hotel in Naha to the port, which is a real advantage for travelers unfamiliar with Okinawa. The coaches are praised for being friendly and comfortable, helping to set a relaxed tone even before the adventure begins.

Once at the port, you’ll join a small group or larger collective depending on the day. The experience is designed to be inclusive, even for solo travelers, with guides who respond attentively to individual questions. The boat itself is owned by the tour company, giving them more control over the experience, especially in terms of selecting the best diving locations.

The Diving Itinerary and Underwater Highlights

Guides carefully choose three of the best dive spots for the day, based on weather and sea conditions. This personalized approach means you’re not just wasting time in less interesting areas but are taken to locations that promise vibrant marine life and clear waters.

The Kerama Islands, around Tokashiki, Zamami, and Aka Island, are known for their colorful coral reefs, diverse fish populations, and potential sightings of larger marine animals like turtles and even sharks, according to some reviews. The guides are experienced and respond well to questions—whether you’re curious about tiny reef fish or larger creatures.

The Unique January 1st Event: Mochi Pounding

One of the more charming aspects is the annual mochi-pounding event held on January 1st. This traditional Japanese New Year custom offers a chance to participate in local culture while enjoying all-you-can-eat mochi. It’s only available with lunch reservations, but it provides a fun, authentic touch to the day that sets this tour apart.

Seasonal Highlights: Whale Watching and Shaved Ice

From January 12th to March 31st, whale watching is included in the tour, offering the chance to spot 4-meter-high whales from the boat. Travelers who have experienced it often mention how whale sightings are quite probable, though weather conditions can sometimes interfere. The boats also rent free waterproof boat coats and have cabin heaters to keep everyone warm in winter, ensuring comfort even when the wind picks up.

In August and September, the tour offers shaved ice service, providing a refreshing break during the summer heat—perfect when exploring Okinawa’s more humid climate.

Comfort and Safety Measures

Diving in winter doesn’t mean sacrificing comfort. The water temperature in the Kerama Islands stays above 22°C (72°F), which is warmer than the outside air during Okinawa’s mild winters, making it quite tolerable. The tour provides a 3mm hooded vest under a 5mm wetsuit, along with free boat coats, cabin heaters, and engine heaters to keep everybody cozy.

For lunch, the tour serves hot Okinawa soba and oden, a warm, hearty meal that helps refuel after a morning of underwater exploration. If you’re still cold, staff have what they call a “secret weapon”—just ask!

Equipment and Additional Costs

Full gear rental—including tanks and weights—is included in the price, ensuring a hassle-free experience. Travelers can also rent cameras or GoPros for capturing underwater moments, though these come at additional costs (3,000 yen for a GoPro rental, 2,000 yen for SD cards).

It’s worth noting that the tour is designed for certified divers. Novices or those without licenses will need to seek other options.

Reviews from Fellow Travelers

• Another highlights the stunning underwater scenery and a welcoming atmosphere for solo travelers.
• Several mention the professional guides and the diverse marine life seen during the dives, including fish, turtles, and sometimes sharks.
• A few reviews note that communication can be challenging if guides don’t speak perfect English, but underwater, this seems less of an issue.
• Less favorable comments highlight crowded boats and short dives—a reminder that the experience can be busy, especially during peak seasons or with larger groups.

Practical Details and What to Bring

Travelers should come prepared with sunglasses, swimwear, sunscreen, and personal medications. Since the tour can be busy, bringing a packed lunch and your dive log helps streamline the day.

Because the tour is for certified divers, proof of certification is required. Minors, pregnant women, and those with certain health conditions are advised to refrain from participating.

Parking on-site costs 500 yen per day, but the tour also offers hotel pickups in Naha, which simplifies logistics.

Who Will Love This Tour?

It’s also ideal for those who want to combine adventure with reliable logistics, thanks to the included transportation, gear, and well-planned itinerary.

However, if you’re a beginner or prefer a more relaxed, non-competitive experience, you’ll want to consider other options. The tour’s busy nature and focus on certified diving mean it’s best suited for travelers with prior experience.
