Provided are a vertical pneumatic fender and a monitoring method for same that prevent a weight connected to the bottom of a fender body from dropping to the sea floor and that can ensure more stable functionality of the fender. A vertical pneumatic fender (1) comprises a fender body (2) having bowl-shaped hemispherical portions (4) joined to both ends in the axial direction of a cylindrical body portion (3), and a weight (7) that is connected to the bottom of the fender body. The vertical pneumatic fender (1) accommodates ballast water (W) in an interior space of the fender body (2), and is provided with a backup chain (9). One end (9a) of the backup chain (9) is connected to the fender body (2) in a position that is offset with respect to the axial line (CL) of the fender body, and the other end is connected to the weight (7). The fender body (2) and the weight (7) are connected with the backup chain in a sack state. The slope of an axial orthogonal reference line (3a) and an axial parallel reference line (3b), which are provided in a region located above the water surface of the outer peripheral surface of the fender body (2), are detected by way of a reference line detector.
