In June 2003, the MP-X was moved to Ebina, Kawasaki in order to conduct continuous observations of rainfall. Its observation range of radius 80 km covers mountainous areas such as Mt. Fuji, Hakone and Tanzawa, and flat areas where big cities such as Tokyo and Yokohama are located.

The MP-X enables simultaneous examination of rainfall distributions at two geologically different positions. There are two existing raingauge networks in the radar observation area, which networks are used for verification of rainfall estimate algorithms. One, the Japan Meteorological Agency AMeDAS raingauge network, provides 10-minute rainfall data with spacing of about 17 km. The other rainguage network is that operated by municipalities such as Tokyo and Kanagawa prefecture, from which is obtained 10-minute rainfall data with spacing of about 5 km.
