Why dive here
With 428+ marine species recorded in the area - including bull sharks, manta rays, mobula rays (devil rays), seahorses and sea turtles - Osaki Lion Fish Palace offers some of Ishigaki & Yaeyama's richest reef diving. Water ranges 23-30°C, warmest July, August, September.
Osaki Lion Fish Palace is one of those easy-going Ishigaki dives that we keep coming back to. It’s a shallow reef, topping out at 19m, making it a comfortable spot for newer divers or those who just want to chill out and take photos. The "palace" itself is a series of small overhangs and ledges, home to a decent number of lionfish – hence the name. You’ll often find them just hanging out, fins flared, completely unfazed by divers. We’ve also spotted pipefish tucked into the corals and plenty of colourful nudibranchs if you slow down and look closely. Visibility here is usually pretty solid, which makes for a relaxing dive without too much fuss.
