Okinawa Blue Cave Scuba Diving Beginner's Guide: Easy & Fun with Cantonese & English-Speaking Instructors

What is the "Blue Cave" in Onna Village, Okinawa?

Located at Cape Maeda in Onna Village, Okinawa, the Blue Cave is one of the world's rare sea caves formed by natural ocean erosion and sunlight refraction. The water inside the cave reflects a magical, dreamlike blue glow, making it a must-visit destination in Okinawa whether you choose Snorkeling or Discover Scuba Diving (DSD).

3 Common Pain Points for Beginners Visiting the Blue Cave & Our Solutions

1. Language barrier and safety instructions you can't understand?

Safety comes first in diving! If your instructor only speaks Japanese or basic English, beginners can easily panic or make mistakes out of nervousness.

👉 DayDayGoodDays Solution: We provide fluent English, Cantonese, and Mandarin-speaking instructors. From mask clearing and snorkel usage to underwater hand signals, everything is explained thoroughly in your preferred language to give you 100% peace of mind.

2. Can I visit the Blue Cave without a diving license?

Absolutely! Even if you can't swim or have never dived before, you can choose:

• Okinawa Blue Cave Snorkeling Experience (From ¥8,250 JPY): Put on a life jacket and float on the surface led by your instructor to admire the blue glow and tropical fish.

• DSD Introductory Scuba Diving for Beginners (From ¥15,250 JPY): Enjoy 1-on-1 or small-group guidance as your instructor takes you 5–10 meters underwater to get up close with the secret wonders of the Blue Cave.

3. Inconvenient shower facilities after diving?

Many diving spots have very basic public facilities, making it easy to catch a cold in the wind after getting out of the water.

👉 DayDayGoodDays Solution: We provide Outdoor Hot Water Showers so you can warm up and rinse off right after your dive, get fresh and clean, and comfortably move on to your next stop!

Tips for Booking Okinawa Blue Cave Diving

• Book 2–4 weeks in advance: Peak diving season in Okinawa runs from May to October, and multilingual instructor spots are limited.

• Curated Underwater Photos: To ensure diving safety, your instructor will take 5–10 curated souvenir photos during safe moments for you to download after the activity. If you'd like to capture the entire adventure yourself, we also offer professional waterproof camera rentals (¥3,500 JPY/unit, please request upon booking), or feel free to bring your own waterproof camera (e.g., GoPro)!
