The ERG (Exploration of energization and Radiation in Geospace) isJapanese geospace exploration project. The project focuses on thegeospace dynamics and accelerations of radiation belt electrons in the context of the cross-energy coupling viawave-particle interactions. The project consists of the satelliteobservation team, the ground-based network observation team, andintegrated-data analysis/simulation team. The ERG satellite will belaunched in FY2016. Comprehensive instruments for plasma/particles, and eld/waves are installed in the ERG satellite to understand thecross-energy coupling system. In the ERG project, severalground-network teams join; magnetometer networks, radar networks,optical imager networks, etc, which provide a gloval view of geospace and complementary observation with the ERG satellite observation. Moreover, the modeling/simulations playan important role for the quantitative understanding. Besides research teams in the project, the science center has been operated. The science data from the project have been archived. Moreover, the science center has developed an integrated data analysis software that are a plug-in for SPEDAS in cooperation with the THEMIS mission. These data and softwares are available via the ERG-Science Webpage
(http://ergsc.stelab.nagoya-u.ac.jp). In thispresentation, we will talk about an overview of the ERG project and discuss the international collaborations with Van Allen Probes, MMS, THEMIS, Cluster, etc and ground network observations under the flame work of Heliosphere/Geospace (H/GSO) system observatory.
