Thank you for your continued support!

The hearing was held at 4:00 p.m. on Tuesday, September 9, 2025, in Courtroom 803 of the Tokyo District Court.

Prior to the same date, the defendants submitted a " Response to the Request for Clarification" (dated August 29, 2025) in response to the plaintiff's previous request for clarification (dated July 7, 2025, asking for questions and clarification regarding the defendant's third preparatory document).

In response to this, the plaintiff submitted Brief No. 7 (dated September 2, 2025) confirming the defendant's claims. Brief No. 7 confirmed the defendant's claims and stated that "if their claims differ from those of the plaintiff, we would like them to clarify their position."

At today's hearing, the presiding judge asked the defendant to respond to the above. However, the defendant replied that he would like one and a half months to respond in writing.

The plaintiff expressed doubts about the need for a new month and a half for a response, as the request merely confirmed the substance of the claims that had already been made repeatedly in writing. The court agreed and instructed the defendant to submit a response within a month at the latest. After discussions, the deadline for the response was set at October 14th.

The plaintiff stated that, given the defendant's "Response to the Request for Clarification," the defendant's arguments could be interpreted as unchanged from the original arguments, and that by the next hearing, the plaintiff would also submit its own arguments, and then submit a statement from the plaintiffs and request for a personal examination. The court also encouraged the plaintiff to prepare the arguments it envisages, regardless of the defendant's response.

Based on the above, the next hearing has been set for Wednesday, October 29th from 11:30am.

The trial is now reaching its climax. We would appreciate your continued support.

Preparatory procedures were held behind closed doors on Wednesday, July 30, 2025, from 1:30 p.m.

The purpose of this hearing was to discuss future progress, as the previously scheduled oral argument date was canceled.

First, the documents submitted by both parties within the deadline were organized.

Plaintiff:Preparatory brief (5) ,Request for clarification (dated July 7, 2025) ,Exhibit Ko 90: "Notice Concerning Partial Revision of the 'Enforcement of the Maternal Protection Act'" (Ministry of Labor Notification No. 1020-1, dated October 20, 2020) ,Exhibit Explanation 6 (Exhibit Ko 90)

Defendant:Third Preparatory Brief , Exhibits 11 to 14,Evidence Explanation ⑷ (Exhibits 11-14)

The third preparatory document submitted by the defendant contained statements regarding the significance of Article 3 of the Maternal Protection Act and its relationship to other articles that could be read in a way that differed from the notices posted by the government and the government's own previous assertions. Therefore, the plaintiff submitteda Request for Clarification (dated July 7, 2025) requesting an explanation.

The court has asked the defendant to respond to this explanation, giving him until August 29th.

The plaintiff's counsel orally confirmed with the defendant's counsel that the general policy in the response would be to withdraw or maintain the claims made in the third preparatory brief, and the defendant's counsel responded that the policy would be to maintain the claims.

The next hearing was scheduled for Tuesday, September 9th, starting at 4:00 p.m., and the hearing has now concluded.

The next oral argument will be open to the public. Please come and observe.

The sixth oral argument hearing, which was scheduled for 11:00 a.m. on Wednesday, July 9th, had to be postponed at short notice due to the judicial body's circumstances.

We apologize for any inconvenience caused to those who had planned to attend.
We are currently working on adjusting the new deadline, aiming for the end of this month, and will report back to you as soon as it is confirmed.

The trial was held in Courtroom 803 of the Tokyo District Court from 2:00 p.m. on April 23, 2025.

We submitted a preparatory brief (4) in which we severely criticized the Defendant for not asserting the legislative intent or necessity of each requirement of Article 3 of the Law.

We have also compiled claims regarding violations of Article 24 of the Constitution.

The court pointed out that our argument for unconstitutionality had some unclear parts, and we were given approximately three weeks to clarify the content of our argument for unconstitutionality.

Based on this, the defendant has decided to submit a written rebuttal to our claims.

The next hearing will be held on Wednesday, July 9th at 11am. Please come and observe.

Thank you all for your continued warm support.

On January 29, 2025, the fourth oral argument in the "My Body Is Not a Mother's Body" lawsuit was held.
Prior to the same date, the defendant country submitted a rebuttal brief ( Defendant's Second Preparatory Brief ).

The contents were as follows:
The right to receive sterilization is not guaranteed by the latter part of Article 13 of the Constitution. The regulatory objective of "protecting the life and health of mothers" is legitimate and the regulatory means (prohibition of sterilization) are also reasonable. All of the requirements set out in Article 3, Paragraph 1 of the Maternal Health Act are reasonable. There is no issue of violation of Article 24, Paragraph 2 of the Constitution.

However, there were many points in the government's arguments that were unclear. For example, the government has long argued that Article 3, paragraph 1 of the Maternal Protection Act "is a requirement to permit sterilization, and therefore does not restrict the rights of the plaintiffs," but has not provided a clear reason for this. In addition, it has not clarified what "protecting the life and health of mothers" specifically means, and there has been no explanation as to why the requirements of endangering life and reducing health due to multiple births are necessary in relation to the purpose of the law, or why sterilization can be said to be a reasonable measure. Therefore, we believe that a major problem is that important assumptions for discussion are not shared, resulting in a situation where arguments do not mesh.

Even though we asked for an explanation in court, no explanation was given, and we were able to confirm that the judge was also aware of the problem that our arguments were not aligned. Therefore, at the next hearing, we plan to clarify the points of discrepancy in our discussions with the government and then refute the defendant's arguments.

The next oral argument hearing will be held on Wednesday, April 23rd at 2:00 p.m. in Courtroom 803 of the Tokyo District Court.
We would appreciate your continued support.

Thank you all for your continued warm support.

On November 1, 2024, the third oral argument in the "My Body Is Not a Mother's Body" lawsuit was held.
Prior to this, I had submitted a written rebuttal to the government stating that "the right to sterilization is not guaranteed by the Constitution," and I gave an oral outline of that statement.

Our argument has three key points:
-The right to receive sterilization surgery is a right to self-determination that combines two aspects: "self-determination as to whether or not to have children" and "self-determination regarding one's own life and body," and is guaranteed by Article 13 of the Constitution.
- The "freedom to use contraception" is a pre-national natural right, and the right to receive sterilization surgery is one such right guaranteed by Article 13 of the Constitution.
- Sterilization surgery is "a matter involving the choice of whether or not to have children" and falls under "matters relating to the family" in Article 24, Paragraph 2 of the Constitution.

The presiding judge then distributed a document illustrating the requirements of Article 3, Paragraph 1 of the Maternal Protection Act, and after confirming the parts that the plaintiff claimed were unconstitutional and invalid, he instructed the defendant (the government) to refute these points.
In fact, the government has deliberately excluded this point from the discussion, arguing that "because it is a requirement for permitting sterilization, it does not restrict the rights of the plaintiffs." We have argued that this provision is the core of the regulation, and is the subject of our argument for unconstitutionality and invalidity.
Through the management of this litigation, we were able to confirm that the judge correctly understood our concerns.
*The documents submitted by the plaintiff ( Preparatory Document 2 , Preparatory Document 3 , Summary of Preparatory Document 3 ) and the documents distributed by the court can be viewed here.

The next oral argument hearing will be held on Wednesday, January 29th at 2:00 p.m. in Courtroom 803 of the Tokyo District Court.
We would appreciate your continued support.

Thank you all for your continued warm support.

The third hearing will be held on Friday, November 1st from 2:00 p.m. in Courtroom 803 of the Tokyo District Court.

At the second hearing held on Wednesday, August 28, the defendant submitted a written rebuttal ( first preparatory brief ) to the contents of the complaint filed by the plaintiff. The government's main rebuttal was that the provisions of the Maternal Health Act, which the plaintiff claims are unconstitutional, do not violate the second paragraph of Article 13 or paragraph 2 of Article 24 of the Constitution.

Therefore, at this third hearing, the plaintiffs plan to refute the government's response to the preconditions and the first preparatory brief submitted last time. On the day of the hearing, the plaintiffs' attorneys will make a presentation on the contents of the documents submitted in advance by the plaintiffs.

In addition, on the day of the hearing, we plan to post any documents submitted by the plaintiffs on this website.

We hope that many people will come.

Thank you all for your continued warm support.
