Would you like to witness the magical coral spawning that can only be seen on a few nights each year?
The coral spawning season has arrived again in Kushimoto!
This special night dive is aimed at observing the spawning of branching corals and table corals!!

Coral spawning is a rare and magical natural phenomenon that can only be seen on a few nights each year. Why not be part of this unforgettable moment?
This night dive gives you the chance to witness one of the fascinating moments in the life cycle of the corals in Kushimoto, home to the world’s northernmost large coral communities.
Since this is a natural event, whether or not spawning occurs depends entirely on nature. We schedule these dives based on our local predictions and conditions.
We would be happy to welcome divers who understand and enjoy the excitement of exploring nature as it is.
