I captured Shiratani Unsuikyo in Yakushima, Japan. Yakushima is a subtropical island off the southern coast of Kyushu and part of Kagoshima Prefecture. It is covered by an extensive cedar forest that contains some of Japan's oldest living trees. Trees that are more than 1000 years old are affectionately called yakusugi (a combination of Yakushima and sugi, the Japanese word for cedar), the most ancient of which may be over 7000 years old.
