A strong cold front has covered Japan, and Ishigaki was no exception – the ground temperature dropped down to 18C, which is considered freezing cold in this subtropical island!

Today we cruised down to Kuroshima and met a lot of Mantas!

We found them even before our entry and saw their fins sticking out of the water.

Even after our entry, they didn’t mind us around at all, and kept enjoying their lunch buffet of plankton!

It was the first time manta encounter for one of our repeater guests.

“I was almost swallowed by its big mouth!”



There were lots of plankton around the surface, together with volcanic pumice.

Hope the mantas will not have stomach aches…


There were Green Turtles swimming around the mantas.


Orangutan crab was wearing its winter costume as usual.


There was an Orange-striped shrimp goby at the sand point of Taketomi.


Ribbon Eel and juvenile Emperor Angelfish are some of the most popular sea life for underwater photographers looking for colorful ones.


Let’s keep ourselves warm and enjoy winter diving!
