Its phase 1 operation has just finished in this June. A BPM system consists of super heterodyne detectors, turn by turn log-ratio detectors with fast gates and detectors for the orbit feedback to maintain stable collision. New X-ray beam profile monitors with multi-slit masks are installed. The bunch-by-bunch feedback system is upgraded using low noise frontend electronics and new 12 bits iGp digital filters. A status of instrumentations of SuperKEKB will be given in this talk.
