After a brief lecture, you will depart on the Starlight Healing Tour with a light in hand, watching underwater creatures that can only be seen at night!

The float of the ring has a rish cord attached, so you don't have to worry about it being washed away. If you float on the water surface and look up, you can observe seasonal constellations and shooting stars.

On the way to the cave, shine an underwater light and observe the nocturnal creatures!

Once inside the cave, we all turn off the lights! When we look into the water in the dark and fan our hands, we see a sparkling underwater world that looks like a small universe.

  • So touching!

    We participated as a couple in our late 50s. My husband has diving experience, but as I can't swim, everything was a first for me! When I inquired about this when I applied, I was told it was OK, so I participated. We received a lecture at the start, then the guide pulled us on a float and we headed out into the night sea! It was my first time seeing the ocean, and I was so excited to discover so many things! When we arrived at the cave, we saw bioluminescent plankton! Beautiful! Amazing! So moving! So moving! We enjoyed it with our whole bodies! It was a shame that we couldn't see the stars because the weather was bad... I would like to experience this again! I was exhausted, but... I was so excited that I couldn't sleep! I was struggling to change position properly in the sea and was struggling, but the guide quickly supported me and I was able to enjoy myself with peace of mind. Thank you very much.

  • Even beginners who can't swim could do it

    I participated with my boyfriend. It was the first time for either of us to wear a wetsuit, and we both can't swim, but we signed up anyway. I think it was great that the instructor took us around holding onto a swim ring. It was a world we'd never seen before. I think it will be a popular experience. I'd like to go again next year.

  • The best!

    We participated as a family. They took the utmost care with safety equipment, and the explanations and guidance were sufficient, so we didn't feel any anxiety about safety. We thoroughly enjoyed the night ocean, the seabed, and the bioluminescent plankton, and it felt amazing! We would love to do it again. However, there are two points I would like to warn future participants about. Make sure the meeting place isn't the same place as before you moved. Also, you should assume that there will be no free photos. Taking photos is impossible. (This review has been machine translated)
