HISUI, a Japanese future spaceborne hyperspectral and multispectral imaging system, is currently being developed by
Japanese Ministry of Economy, Trade, and Industry. Because of the narrow swath of the imager as well as the limits on
the operation time and data downlink resource allocation, the operation strategy of HISUI should be examined
thoroughly to fully utilize HISUI's earth observation capability. A software which simulates HISUI's operation is being
developed for the detailed analysis of HISUI's long term operation plans. The simulation results indicate that 1) one-time
priority area mapping will be completed within eight months with moderate data downlink allocation, 2) one-time global
observation in a year will be possible if the allocated downlink capability is more than 250 GByte per day, 3) the
nighttime volcano monitoring will not significantly affect the daytime observation if the cross track pointing only for
nighttime observation is not allowed.
