DNA DATABANK OF JAPAN(DDBJ)

DNA Data Bank of Japan (DDBJ) is the sole nucleotide sequence data bank in Asia, which is officially certified to collect nucleotide sequences from researchers and to issue the internationally recognized accession number to data submitters. Since we exchange the collected data with EMBL-Bank/EBI (European Bioinformatics Institute) and GenBank/NCBI (National Center for Biotechnology Information) on a daily basis, the three data banks share virtually the same data at any given time. The virtually unified database is called "the International Nucleotide Sequence Database (INSD)". DDBJ collects sequence data mainly from Japanese researchers, but of course accepts data and issue the accession number to researchers in any other countries.
DDBJ is organized by the Center for Information Biology and DNA Data Bank of Japan (CIB-DDBJ) of the National Institute of Genetics (NIG) with endorsement of The Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT). 99% of INSD data from Japanese researchers are submitted through DDBJ.
The principal purpose of DDBJ operations is to improve the quality of INSD, as public domains. When researchers make their data open to the public through INSD and commonly shared in world wide, we at DDBJ make efforts to describe information on the data as rich as possible, according to the unified rules of INSD, preferably without any stress by using DDBJ.
