Developing new instruments and upgrading existing instruments has been an important aspect of Subaru telescope's operation. Seven facility instruments and two visiting instruments are currently under use. Among them HiCIAO, a coronagraphic imager combined with adaptive optics (AO188), has started its full operation in the 2nd semester of 2009. We are using HiCIAO for a large program (SEEDS) to find new exo-planets and comprehend planet formation from proto-planetary disks. To achieve higher contrast, a new coronagraph attachment with an extreme AO (SCExAO) will be installed as a PI instrument. AO188 is also used with the IRCS in natural guide star mode. Its laser guide star mode is currently commissioning. The Fibre multi-object spectrograph (FMOS), which is comprised of 400 fibers placed at the prime focus and delivers 0.9-1.8um spectra, will be partly offered to open use from mid 2010. Hyper Suprime-Cam, the wide-field upgrade (1.5 deg FoV) of the Suprime-Cam, is under development for its first light in 2011. Development of an immersion grating has taken place for upgrading the IRCS with a high-resolution infrared spectrograph.
