Each inn is equipped with air conditioning. Since the island is surrounded by the sea, there is no extreme heat due to the heat island phenomenon like in the city, and there is no extreme cold such as heavy snow and freezing. Even so, the recent rise in summer temperatures and the cold winters are also in  Teshima.

For this reason, the temperature is controlled by air-conditioning in the summer and heating by the air-conditioner and the hot carpet in the winter. However, please feel the natural air and climate of the island without using the air conditioner as much as possible.
