About Uminchu
Uminchu is a boat-access artificial-reef dive off Tokashiku Beach on Tokashiki Island in the Kerama Islands. White sand, reef structure, and clear water make it a straightforward beginner dive when conditions are settled. The site is known for clownfish, snappers, butterflyfish, and other small reef fish, but it can also pick up a stronger current at times, so it works best as a guided boat dive with local briefing.
