	Installation and assembling of accelerator components for J-PARC 50 GeV Synchrotron are now underway. Off-beam commissioning will be carried out between December 2007 and April 2008, and the full commissioning of J-PARC accelerator complex, which is consisted of an injector linac, a 3 GeV rapid cycling synchrotron and the 50 GeV Synchrotron, will be started from May 2008. This paper describes the status, schedule and method of installation and assembling of accelerator components. Radiation maintenance scenario will be also described.

	The KEKB is an electron-positron two-ring collider for the leading B meson factory. It consists of an 8 GeV electron ring (HER) and a 3.5 GeV positron ring (LER) and their injector linac. It has been operated since December 1998, and has recently marked the peak luminosity of 16.52 /nb/s. This peak luminosity is obtained under the crab-ready beam optics having the robust operating condition by some efforts to solve the optics problems. The integrated luminosity has also recently exceeded 1.2 /fb /day under the continuous injection mode. We are aiming more luminosity improvement after the crab cavity installation. Further the major upgrade plan for SuperKEKB is expected to achieve 400 /nb/s keeping the baseline of the original proposal and another upgrade plans are also considered towards over 1000 /nb/s based on the recent beam-beam simulation. This paper describes the recent status of KEKB and upgrade plans for SuperKEKB.
