Present status of acid deposition monitoring in East Asia and Japan was introduced. The Acid Deposition Monitoring Network in East Asia (EANET) started its preparatory-phase activities in 1998. Ten participating countries accumulated monitoring data concerning wet-deposition, dry-deposition, soil and vegetation, and inland aquatic environment. Formal stage of the EANET will start by the decision of the Second Intergovernmental Meeting from January 2001 taking into consideration the result of the preparatory-phase activities. Environment Agency of Japan have been carried out several national surveys on acid deposition monitoring. There were 48 monitoring sites across the nation at the end of the Third Survey in 1997. The states of the acid precipitation observed in Japan are almost same as in western countries. Precipitation amount of nss-SO_4^<2-> is decreasing, while the contribution of the NO_3^- to the acidification became lager in these years.
