[7][8] The role of Himawari 8 is to provide typhoon, rainstorm, weather forecast and other related reports for Japan, East Asia, and Western Pacific region.

[13] The Australian Bureau of Meteorology CEO Dr Rob Vertessy stated that Himawari 8 "generates about 50 times more data than the previous satellite".

[12] A recent study reported that Himawari-8 had acquired cloud-free observations every 4 days, while capturing the seasonal changes of vegetation in the cloud-prone region of Southeast Asia more accurately than before.

[14] (μm) number resolution at SSP (km) The Space Environmental Data Acquisition Monitor (SEDA) is the second instrument aboard Himawari 8, and it consists of two sensors: SEDA-e for detecting high energy electrons and SEDA-p for detecting high energy protons.

[16] The data from this instrument is transmitted to a ground station in Saitama, Japan with a Ka-band signal and is ultimately provided to the National Institute of Information and Communications Technology (NICT) for use monitoring space weather events along the Japanese meridian.
