Overview of KAGRA data analysis KAGRA is planning to perform the first observation during FY2019. This is done together with LIGO-Virgo O3. New MOU between LIGO-Virgo and KAGRA are now prepared in order to perform joint observation and joint data analysis. A lot of efforts are necessary to perform start this observation in data analysis KAGRA data will be shared with LIGO-Virgo, and will be jointly analyzed. LIGO-Virgo are conducting data analysis completely jointly. We have to establish an organization for this joint data analysis. KAGRA data analysis group was reformulated in order to have a good matching with corresponding LIGO-Virgo data analysis working groups 3
