Japan's education ministry and health ministry have opened four separate public comment procedures tied to a new law regulating the handling of human genome-edited embryos, according to notices posted on the e-Gov public comment portal on October 30, 2026 [1][2][3][4]. All four relate to the implementation of the Act on Regulation of Handling of Human Genome-Edited Embryos, identified as Reiwa 8 Law No. 70 [2][3][4].

The first comment call, from the Ministry of Education, Culture, Sports, Science and Technology's Research Promotion Bureau, Life Science Division, Bioethics and Safety Office, concerns amendments to several related ethics guidelines following the enactment of the law [1]. The proposed changes include a full revision of the Ethical Guidelines for Research Creating Human Fertilized Embryos, partial revisions to the Guidelines for the Establishment of Human ES Cells, the Guidelines for Institutions Distributing Human ES Cells, and the Guidelines for the Use of Human ES Cells, as well as a partial revision to the Guidelines for Research on Creating Germ Cells or Human Embryo Models from Human iPS Cells [1]. The ministry also proposes abolishing the Ethical Guidelines for Research Using Provided Human Fertilized Embryos for Genetic Information Modification Technology [1]. This comment period opened at midnight on October 30, 2026, and closes at 23:59 on November 30, 2026 [1].

The remaining three comment calls come from the Ministry of Health, Labour and Welfare's Minister's Secretariat Health Science Division, each closing at 23:59 on November 28, 2026 [2][3][4]. The first of these concerns a draft Enforcement Order for the law, based on Article 2, item 3, Article 3, and Article 6, paragraph 2, item 1 of the Act [2]. The second concerns draft Enforcement Regulations for the law, based on Articles 6, 9, 10 and 11 as well as Supplementary Provision 3 [3]. The third concerns a draft Guideline on the Handling of Human Genome-Edited Embryos, based on Article 4 of the Act [4].

All four notices state that comments are being solicited under the Administrative Procedure Act [1][2][3][4]. The ministries have published draft texts and summary materials for each proposal, including PDF documents with the full or revised provisions, for review before comments are submitted [1][2][3][4]. Each notice stresses that submitters should fully review both the comment solicitation guidelines and the full text of the proposed rules before submitting an opinion, to avoid mistaken submissions [1][2][3][4].

The sources do not specify what the underlying law itself requires beyond the articles cited, nor do they describe how genome-edited embryos would be regulated in practice [1][2][3][4]. They also do not state who is eligible to comment or how submissions should be formatted, beyond directing the public to the published comment solicitation guidelines for each notice [1][2][3][4]. Readers interested in the content of these draft rules, including the ethics guideline revisions and the enforcement order, regulations and guideline tied to the new law, should consult the official documents linked on the e-Gov portal and contact the relevant ministry division listed in each notice [1][2][3][4].
