Best season is
from spring to summer
The best season is from spring to summer.

On the other hand, in winter in Ishigaki Island, the north wind blows, so the sea around "Aonodoukutsu" tends to be rough due to the north wind.

Despite the rain, "Aonodoukutsu" shines blue, and you can enjoy a different mysterious space.
Observe a stalactite cave
The formation of the "Aonodoukutsu" cave
The 'Aonodoukutsu' cave in Ishigaki Island is a stalactite cave formed through the accumulation and solidification of coral and marine organisms.
Originally, limestone was shaped by the accumulation of coral and marine organisms. Subsequently, weakly acidic rain permeated the limestone, gradually dissolving the interior and creating a cavity.
The dissolution of the cavity progressed over an extended period, eventually giving rise to a vast cave.
A compelling indicator of this process is the presence of numerous 'icicles' formed by the reaction between leaked rain's carbon dioxide and limestone on A compelling indicator of this process is the presence of numerous 'icicles' formed by the reaction between leaked rain's carbon dioxide and limestone on 'Aonodoukutsu'.
When you look inside the cave from the sea, the light coming in from outside, the freshness of the sea, and the blue of the sky stand out even more.
The "blue" of the Aonodoukutsu may refer to the blue of the sky as well as the sea.
