ASTRO-H is the 6th Japanese satellite for X-ray astronomy,

and it will be launched in FY2015. ASTRO-H covers a very

wide range from 0.3 to 600 keV with four instrument systems;

Soft X-ray Telescope (SXT) + Soft X-ray Spectrometer (SXS),

SXT + Soft X-ray Imager (SXT), Hard X-ray Telescope (HXT) +

Hard X-ray Imager (HXI), and Soft Gamma-ray Detector (SGD).

Nagoya University have made significant contributions to the

project, in particular to the HXT and SGD. In this talk, I

will introduce ASTRO-H and give some examples of what the

observatory can do. Then future projects among the world

after ASTRO-H, especially Athena, are introduced if time

permits.
