“I've snorkeled both in Japan and abroad, but this was hands down the best. The location and service are worthy of being the highlight of any trip.”
A — Couple with 2-year-old
“I've snorkeled at Kerama, Minna, Sesoko, Blue Cave, and more — but this was the most fulfilling tour ever. Being private, they listened to our wishes and adapted to the conditions.”
K16.N — Repeat guest
“4 of our 6 were seniors — some couldn't swim, others were nervous about snorkeling. But the guide was so patient that everyone said it was the best memory of the trip.”
ma_mi — Family of 6
“Family of four (6-year-old daughter, 10-month-old son). We were worried with such small kids, but felt completely safe and had a wonderful time!”
Y.K. — Family with young children
“Our kids who used to be afraid of the ocean now want to come back. They adapted the plan on the spot for our children — first-time snorkelers had no issues at all.”
H.O — Family with children
“They kindly accommodated our last-minute request just hours before departure. An absolutely unforgettable experience.”
