  Japan Astrometry Satellite Mission for INfrared Exploration (JASMINE) is a
planned M-class science space mission by the Institute of Space and
Astronautical Science, the Japan Aerospace Exploration Agency. JASMINE has two
main science goals. One is the Galactic archaeology with Galactic Center
Survey, which aims to reveal the Milky Way's central core structure and
formation history from Gaia-level (~25 $\mu$as) astrometry in the Near-Infrared
(NIR) Hw-band (1.0-1.6 $\mu$m). The other is the Exoplanet Survey, which aims
to discover transiting Earth-like exoplanets in the habitable zone from NIR
time-series photometry of M dwarfs when the Galactic center is not accessible.
We introduce the mission, review many science objectives, and present the
instrument concept. JASMINE will be the first dedicated NIR astrometry space
mission and provide precise astrometric information of the stars in the
Galactic center, taking advantage of the significantly lower extinction in the
NIR. The precise astrometry is obtained by taking many short-exposure images.
Hence, the JASMINE Galactic center survey data will be valuable for studies of
exoplanet transits, asteroseismology, variable stars and microlensing studies,
including discovery of (intermediate mass) black holes. We highlight a swath of
such potential science, and also describe synergies with other missions.
