CiNii Articles counts each referenced datum from the Citation Database for Japanese Papers as a single record.
In most cases, when the "Databases: " field has only "CJP ref", only simplified information (e.g. bibliography in a references list) is available.
Please note that entries are presented as they originally appeared, and NII cannot correct any errors in the data.
