HISUI (Hyperspectral Imager SUIte) is a pushbroom hyperspectral imaging instrument mounted on the Japanese Experiment Module Exposed Facility of the International Space Station (ISS). [^hisui-sensors] Operated by Japan's Ministry of Economy, Trade and Industry (METI) and developed with Japan Space Systems, HISUI was deployed to the ISS in December 2019 and began routine data acquisition from a non-sun-synchronous orbit at approximately 400 km altitude and 51.6 degree inclination.

The instrument covers the visible to shortwave infrared range (400-2500 nm) at 185 spectral bands and 30 m spatial resolution, with a swath of approximately 20 km at nadir. [^hisui-sensors] Data are available through the Tellus geospatial platform operated by Japan Space Systems, with a radiometric correction update released in February 2026. [^hisui-distribution]
Mission status as of May 2026 is under review. The CEOS EO Handbook lists an end-of-life date of December 2025 and classifies the mission as operational (extended). [^ceos-hisui] The hisui.go.jp distribution page shows data services active on Tellus as of 2026-05-24 with the February 2026 radiometric release, and no formal end-of-mission announcement had been published as of that date. [^hisui-distribution] Whether operations continued beyond the planned December 2025 end date has not been formally confirmed by METI or Japan Space Systems as of this record.
