Sea condition was a bit choppy, but the weather was great today! Some of the guests got totally cooked in one day!


The first dive of the day was Sakieda Big Arch. Corals around here was once totally dead due to outbreak of Crown-of-thorns starfish around 7yrs ago, but it is now recovering!


There are tons of Sixbanded sergeantmajor and Indo-Pacific sergeant (a bit yellow ones) around the shallow reef area.


We had two guests in our AOW course today, and here is a photo of their deep dive session. You can see the small air bubble expanding as they go up.


Our staff Satoko’s favorite – Oriental butterflyfish, juvenile.


There was no manta at Kabira Manta Scramble today… So the advanced divers went diving at Yonara Channel, and there was one 🙂


The last dive of the day was at Iriomote – Nobaru Drop Off.


Typhoon Mangkhut has shifted its course a bit down south, so hopefully there is not much impact here. Hope everyone around Taiwan and Philippines will be ok… Stay safe!
