Atami Kosoga Cave
★★★★☆
(241)
Kosoga Cave in Atami, Shizuoka, is open Nov–Apr and features a 40m semi-enclosed cave at 6–12m depth, ideal for beginners. Its wide space and open ceiling let sunlight create a stunning blue gradation. Just 10 minutes by boat from Atami Port, it’s both scenic and accessible.
The cave hosts schools of snappers, rockfish, and mackerel flowing like a river under light, with nearby sands hiding sharks and bullhead sharks.
