Q Can the Blue Cave be visited all year round?
A Blue cave tours in warm regions of Japan such as Okinawa are held all year round, but the tourist season for Hokkaido and blue caves is generally from spring to autumn. Hokkaido in winter is not often practiced because it is cold and the sea is often rough. Some operating companies carry out tours in the fall and winter, but it is undeniable that there is a high possibility that they will be canceled due to the above reasons.
Q What is a blue cave?
A Blue cave is the name of a cave that exists all over the world. Most of them are composed of near-white limestone and are half submerged in the sea. When sunlight falls into the sea, most of the light is absorbed by the water, and the human eye recognizes only the remaining blue color. Furthermore, the white seabed of limestone reflects light and the surface of the sea inside the cave appears to glow blue, hence the name.
