There are many activities to enjoy while staying on Kitadaito Island. If you have the time, go diving during calm seas for taco Octopus or giant clams with a local guide. Its a fun way to see the ocean life and get a tasty meal.
Another fun activity is cliff diving. There are three ports on Kitadaito, and when the weather permits the locals take the time to jump off the lower piers and swim in the ocean around there. If you bring goggles you will also be able to see a myriad of fish and other ocean wild life.
Kitadaito also plays host to several Mastsuri or festivals. The largest festival is held in the middle of September and includes both Edo and Okinawan sumo plus a day devoted to portable shrines omikoshi. The Daito islands are the only Okinawan Islands to include the shrines in their festivals, because their first inhabitants came from Hachijojima.
