It was cloudy all day.

Wind was blowing from the south, so we cruised up north.

The first dive of the day was Osaki Purple Queen Reef.

We said the season has started for Giant cuttlefish, but it has not been stable…

We see them here and there, but they are now spawning, and swim away.

Maybe a couple of more weeks and we will start to see them spawning 🙂


A big Stellate puffer was resting on a reef.


We found a tiny Lobster, probably around 3cm!

We see lots of big ones, but this is cute!


At Manta City, there were many boats today, and we waited for a while.

It was worth the wait!

There were four mantas circling around the reef when we arrived, and after they were gone, another one arrived and stayed for a long time 🙂


Some of our guests today came from the main island of Okinawa, where Mantas are rare.

Glad you were able to meet them!


Four students for AOW course…


And they all completed the required skills successfully!



Here are some of the most frequent visitors for Prime Scuba Ishigaki.

Nishiyama-san has been living in Ishigaki, and has been diving with us every months, but this is her last month as she is moving out 🙁

But of course, we will be looking forward to your visits, even after moving out 🙂


We are sure you will miss this blue water!
