[2024-09-01 11:00] The problem of keyword search has been solved. You can use it as usual.
I’m sorry to have troubled you for so long.
Thank you and best regards,


There are disabilities in the DDBJ Search keyword search functionalities.

  • DRA (sra-submission, sra-experiment, sra-run): keyword search works for accession numbers and keywords.
  • JGA (jga-study): keyword search works for accession numbers and keywords.
  • BioProject (bioproject): keyword search DOES NOT work for accession numbers and keywords.
    If an accession number is known, please directly access URL in the form of https://ddbj.nig.ac.jp/resource/bioproject/[bioproject_accession].
    Example, https://ddbj.nig.ac.jp/resource/bioproject/PRJDB12105
    You may also search at NCBI BioProject and EBI.
  • BioSample (biosample): keyword search DOES NOT work for accession numbers and keywords.
    If an accession number is known, please directly access URL in the form of https://ddbj.nig.ac.jp/resource/biosample/[biosample_accession].
    Example, https://ddbj.nig.ac.jp/resource/biosample/SAMD00394581
    You may also search at NCBI BioSample and EBI BioSample.

We apologize for the inconvenience caused by this.
