We really saw dolphins! There is a guide who can speak Japanese, so you can rest assured.
It had been over 15 years since I last swam, so to be honest, it was really tough to jump into the strong waves offshore and follow him (my husband can't swim, so he retired after the first dive), but it was a great memory.
When I snorkeled in the shallow water, the waves were calm and even my husband, who can't swim, was able to go into the water and see some sea turtles. We had a wonderful photographer take a lot of pictures, so we were able to get some memories of her husband at the beach, who didn't spend much time at the beach!
The service was also good and I was very satisfied. it's recommended.
