In 1995, the World Meteorological Organization (WMO) Second International Symposium on Assimilation of Observation in Meteorology and Oceanography was held in Tokyo, which initiated the Japanese Summer School on Data Assimilation. Over the past 20 years, the ocean data assimilation research community in Japan has accomplished remarkable achievements, including the successful prediction of the Kuroshio large meander and the development of a coupled atmosphere-ocean four-dimensional variational data assimilation system, which is the only one in the world. Ocean data assimilation systems are now operationally used to monitor and forecast the ocean state, and their products, or ocean reanalysis datasets, are broadly provided for oceanographic and climate studies, fisheries management, the prevention of oceanic disasters, and the maintenance of coastal areas. This paper provides a summary of the achievements of the research community, the current status of ocean data assimilation products, and ongoing research subjects in the community. Additionally, the requirements for successful progress in this research areas are discussed from a future perspective.
