Recent activities in Japan to deploy a data grid for high energy physics will be reported. Japanese collaboration of LHC- ATLAS experiment is now preparing a Tier-2 analysis center at Tokyo. Several institutes/universities have girl facilities and they are connected to the Tokyo Tier-2 center. Collaborators of Phenix of RHIC at BNL and CDF of tevatron at FNAL are also using grid using grid tools for data transmission.
