Glide over Kabira Bay's legendary coral gardens in a glass-bottom boat, then snorkel its protected turquoise shallows — home to black pearls and some of Japan's most biodiverse reef life. The bay's swimming ban makes this boat-only access genuinely exclusive.
What to expect
You board a low-slung glass-bottom boat and drift over electric-blue water above brain corals, sea turtles, and schools of tropical fish. The bay is legally off-limits to swimmers, so this vessel is your only window into its underwater world. Opt for the snorkel extension at a nearby cove for a hands-on reef encounter. The whole experience unfolds against a backdrop of jungle-draped hills and pearl farm buoys that have graced this bay for centuries.
Good to know
Kabira Bay is a 30-min taxi ride from the cruise pier (approx. JPY 3,000 each way). Book the private snorkel slot directly by email or phone at least 48 hours in advance. Confirm your all-aboard time and allow 90 minutes for the return journey.
