Here’s the bucket list for your day ashore: the most extraordinary thing to do at each stop, and the private, small-group, or expert-led way to make it yours — your own pace, real access, none of the crowd.
In port at Ishigaki, the bucket-list move is Kabira Bay Glass-Bottom Boat & Private Snorkel Safari. Kabira Marine Service (川平マリンサービス) runs it — a private, expert-led experience at your own pace, not a 40-person coach. Below: all 6 bucket-list things to do on a Ishigaki port day, each with the independent way to make it yours.
1water
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.
Book it withKabira Marine Service (川平マリンサービス)JPY 1,500 per person (glass-bottom boat, ~30 min); private snorkel add-on from JPY 6,000 per person
