The most famous dive site in Izu eastern area!
It is easy access from Tokyo.
The facilities for divers are well prepared, so you can enjoy scuba diving for all season.
Well... the water is not always clear, but we can feel seasonality in the ocean.
Greg Helton June 16th, 2015 - 3:00:I dove at IOP several times and during all seasons. The water hovers around 16 degrees C during the summer and a somewhat chilly 12 degrees C in the winter. However the waters are crystal clear in the winter and visibility is poor in the summer. Life is abundant year round with huge groupers residing at the site's underwater cliffs.
