Accessible all year round!
Best season is
from spring to summer

【Ishigaki Island, Okinawa】BLUE-CAVE TOUR

"Aonodoukutsu" in Ishigaki Island can be enjoyed all year round. The best season is from spring to summer.

In spring and summer, the main wind in Ishigaki Island is the south wind. "Aonodoukutsu", located in the northern part of Ishigaki Island, is less affected by this south wind and is in a calm state with few waves.

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.

However, even in the winter season, you can go to "Aonodoukutsu", so it is a spot that can be enjoyed all year round.

Tours are generally held even in the rain. Despite the rain, "Aonodoukutsu" shines blue, and you can enjoy a different mysterious space.

 

Observe a stalactite cave

【Ishigaki Island, Okinawa】BLUE-CAVE TOUR

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 the cave's ceiling in 'Aonodoukutsu'.

【Ishigaki Island, Okinawa】BLUE-CAVE TOUR

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.
