CiNii is including articles information and linking to fulltext of J-STAGE by JST (Japan Science and Technology Agency) when it is permitted by the publishing society.
It had been stopped from December 2011 updating of J-STAGE data because of system renovation of J-STAGE and interface between CiNii and J-STAGE.
But the updating has been restarted from December 2012.
It will be updated once in around 2 month temporarily.
Thank you for your understanding.
