Even those who can't swim can confidently participate in this activity. It's natural to feel a bit nervous the first time, but Mr. Kobayashi patiently explained each step and safety measure, which put us at ease. Mr. Kobayashi, the diver, and the boat driver were all very friendly. When entering the water, you might feel a slight ringing in your ears (this varies from person to person), but it doesn't affect the activity. Once you're in the ocean, it's like entering a new world, and any initial nervousness disappears! The weather on the day we participated was cloudy, but even so, we still encountered beautiful schools of fish underwater. We spent about 20-25 minutes in the water. The diver will help take great photos! Your neck and head will mostly stay out of the water, so even if you're wearing makeup, you can participate with confidence! Highly recommended! 👍🏻
