Abstract: Japanese glaciologists and geographers believed that there are no active glaciers in
Japan. We studied the surface ﬂow velocity and ice thickness of the Gozenzawa perennial snow
patch in Mt. Tateyama (-*+/ m asl), and the Sannomado and the Komado perennial snow patches in
Mt. Tsurugi (,333 m asl) in the northern Japanese Alps, central Japan, since ,**3. The Sannomado
and the Komado perennial snow patches have large ice masses (¸-* m in thickness). We measured
the surface ﬂow velocity and found that both the ice masses had ﬂowed over -* cm month+ in the
autumn of ,*++. Hence, we regard both the snow patches as active glaciers. The Gozenzawa
perennial snow patch too has a large ice mass (,1 m in thickness). We measured the surface ﬂow
velocity and found that the ice mass had ﬂowed slightly (¹+* cm month+) in the autumns of ,*+*
and ,*++. Hence, we regard this snow patch also as an active glacier.
