All the staff who guided us were friendly and helpful. There's parking behind the store, as well as lockers and changing rooms for your personal belongings. The showers even have hot water and shampoo and body wash. All you need to do is bring a towel. The tour was friendly and accommodating. Of course, it was my first time scuba diving, so I was a bit nervous, but the guides were very helpful and I was able to adjust quickly and participate. If you're Korean, you'll need to communicate in Japanese or English since the staff don't speak Korean. However, don't worry, they'll be able to communicate without much trouble! After the tour, a cat named "Kurochan" will be waiting at the port. Be sure to meet him. I'd like to express my gratitude to the staff. Stay healthy!
Emma No.1 is surprisingly from the same hometown and lives very close by, haha! Overall, it was great, and my friend who accompanied me also had a lot of fun. See you tomorrow, haha!
Our snorkeling trip coincided with a typhoon. Although the typhoon didn't actually make landfall, the Japanese authorities closed the Blue Cave, prohibiting snorkeling and diving. So we went to a nearby beach instead. The water there was very calm and safe, which reassured us, although it was a little disappointing! Our family of five, three of whom can't swim, had signed up for a group snorkeling trip, but due to insufficient participants, it became a private tour. The instructor explained the activity entirely in Chinese, providing very clear instructions. He had us change into our wetsuits and then led us to the shore, carefully demonstrating how to wear masks and use snorkels. Even non-swimmers shouldn't be too nervous; he guided us while we held onto the float. The process was actually very easy. The water was very calm, and the depth wasn't great; we could touch the bottom in most areas, so we weren't afraid. Later, we just let go and swam easily! The water was very clean, and we saw many different kinds of fish. The instructor even gave us some bait to feed them! He took photos and videos throughout the trip and sent them to us later! I can't swim, but this was my third time snorkeling, and I felt it was perfect for beginners. Although I'm not sure about the actual conditions at Green Cave, based on my experience, snorkeling is a very relaxing activity with no need to be nervous or afraid! Thank you to the instructor for leading the way; my family and I had a great time! ☺️
A very good experience; the timing and itinerary are suitable for beginners. The leader was very nice, gentle, and caring. We took many photos during the trip and are very satisfied.
Due to the weather, the Blue Cave -> Jane Beach snorkeling was changed, but I received a KakaoTalk message in advance regarding the change and was able to receive a quick response. All the staff were so friendly 乃 (thumbs up) Afterwards, soba and onigiri were served for dinner, which was delicious because they were freshly made (the shrimp tempura was piping hot). We also ordered beer and had a drink ~ Wow~ The amazing view while eating is a bonus! I want to use it again if I visit again! Thanks to you, I was able to have a pleasant trip. I hope you prosper! Cons: After snorkeling, the shower room is open, so you have to splash yourself with water while wearing your swimsuit and change clothes in the private changing room ~ I think it's better to wear a shorter swimsuit rather than a long one so that it's easy to put on and take off the wetsuit!
