The Japanese Pharmacopoeia is an official standard that the MHLW stipulates for proper properties and quality of pharmaceuticals by seeking opinions from the PAFSC under Paragraph 1, Article 41 of the Law on Securing Quality, Efficacy and Safety of Products including Pharmaceuticals and Medical Devices (Act No. 145 of 1960)
In order to ensure the proper properties and quality of pharmaceuticals, the MHLW will set forth and make public notice of the JP after gaining opinions from the PAFSC. The MHLW must consult with the PAFSC on any revisions to be made through discussions on all aspects of the JP made by the PAFSC at least every ten years.
