Short summary
Kakioka Magnetic Observatory (KMO) has been monitoring the geomagnetic field and electric field at Kakioka, Japan, since 1913. It has promoted a variety of observations and research activities. In 1972, KMO developed the Kakioka Automatic Standard Magnetometer (KASMMER) system, which enabled them to provide geomagnetic field data of the highest quality. Today, KMO operates a network of observatories in Japan and maintains the observations with the longest history in East Asia.
