Abstract
Mt. in Southern Kyusyu is the generic name for a total of 22 volcanoes forming the so-called Kirisima volcanic group . These volcanoes are arranged linearly in a NW-SE direction, extending some 13 km. It is remarkable that 15 of them have perfect craters, 8 being filled with water and forming picturesque crater lakes. One of these 15 lakes, Mi-ike, is the deepest crater lake in Japan. Three limnological trips to these lakes were made by the present writer together with Dr. S. YOSHIMURA, the first in February, 1936, the second in July of the same year, on both occasions with a portable rubber-boat, except in the case of Mi-ike, while the third trip was made in February, 1937. With the exception of Mi-ike and Onami-ike, these crater lakes were explored limnologically for the first time.
