UNITED STATES DISTRICT COURT EASTERN DISTRICT OF MISSOURI EASTERN DIVISION

NAOTERU TSURUTA, ) ) Petitioner, ) ) v. ) Case No. 4:22-CV-00425-SPM ) SARAH MARGARET TSURUTA, ) ) Respondent. )

MEMORANDUM OPINION AND ORDER This matter is before the Court in this closed case on Respondent Sarah Margaret Tsuruta’s Motion for Relief from Judgment. ECF No. 76. Petitioner Naotero Tsuruta has not responded to the motion. For the following reasons, the motion will be denied. I. BACKGROUND On April 12, 2022, Petitioner Naoteru Tsuruta (father of minor child L.T.) filed a Verified Complaint and Petition for Return of Child Under the Hague Convention on the Civil Aspects of International Child Abduction (the “Hague Convention”), October 25, 1980, 1343 U.N.T.S. 22514, as implemented by the International Child Abduction Remedies Act (“ICARA”), 42 U.S.C. § 9001 et seq. Petitioner alleged that in October 2021, L.T.’s mother, Respondent Sarah Tsuruta, wrongfully removed L.T. from Japan and retained L.T. in Missouri. Petitioner sought an order requiring that L.T. be returned to Japan. The Court held a trial on August 5, 2022. On September 19, 2022, the Court entered a Memorandum Opinion and Order finding that Petitioner had established all the elements of a prima facie case for return under the Hague Convention1 and that Respondent had not established

1 “To establish a prima facie case for return of the child under the Convention, the petitioner must show, by a preponderance of the evidence, that: (1) immediately prior to removal or retention, the child habitually resided in another Contracting State; (2) the removal or retention was in breach of the petitioner’s custody rights under that State’s law; and (3) the petitioner was exercising those either of the affirmative defenses she asserted.2 ECF No. 38. On the same date, the Court ordered that L.T. be returned to Japan and entered judgment in favor of Petitioner. Id.; ECF No. 39. On August 10, 2023, the Eighth Circuit Court of Appeals affirmed this Court’s judgment. ECF No. 74. On August 20, 2025, nearly three years after this Court entered its judgment, Respondent filed the instant Motion for Relief from Judgment pursuant to Rule 60(b) of the Federal Rules of Civil

Procedure. Respondent asserts that she has discovered that Petitioner misled her and the Court into incorrectly believing that the parties were legally married and that Petitioner had custody rights to L.T. Respondent states that as part of her efforts to connect with L.T. after L.T.’s return to Japan, Respondent “has recently discovered that the parties were not, in fact, legally married in Japan.” ECF No. 76, at ¶ 8. She states that to become legally married in Japan, adults are required to sign documentation that is then filed with the local Family Registry where they are residing. Id. She acknowledges that at trial, both parties represented that to the Court that they were married, having signed and filed such paperwork as required. Id. However, she states that “[i]t has only recently come to light that Respondent never signed such paperwork, and that Petitioner forged her signature to it.” Id. She asserts that “Petitioner was not truthful with Japanese authorities nor this Court about this

alleged marriage status, and Respondent told this Court what she believed based upon what Petitioner falsely represented to her.” Id. She argues that because the parties were not legally married, Petitioner

custody rights at the time of the removal or wrongful retention.” Custodio v. Samillan, 842 F.3d 1084, 1088 (8th Cir. 2016). “If a petitioner establishes a prima facie case, the child must be ‘promptly returned unless one of the narrow exceptions set forth in the Convention applies.’” Id. at 1089. (quoting 22 U.S.C. § 9001(a)(4)). Neither the second element nor the third element of the prima facie case was disputed by the parties at the time the Court entered judgment. See Respondent’s Proposed Mem. Opin., ECF No. 36, at 17 (“The parties do not dispute that Petitioner had rights of custody at the time Respondent returned to the United States, nor do they dispute that these rights were being exercised.”). The only issue in dispute with respect to the prima facie case was whether Japan was L.T.’s habitual residence immediately prior to her removal from Japan. See id. 2 Respondent asserted two affirmative defenses: (1) that returning L.T. to Japan would present a grave risk of physical or psychological harm to L.T. or would otherwise place L.T. in danger; and (2) that Petitioner consented and subsequently acquiesced to Respondent’s retaining L.T. in the United States. was not entitled to custody of L.T. under the laws of Japan. Id. at ¶ 10. She therefore argues that Petitioner did not show that the removal or retention of L.T. was in breach of Petitioner’s custody rights under Japan’s laws, as is required for a prima facie case of return. Id. (citing Custodio, 842 F.3d at 1088). She argues that the Court’s prior order must not remain in force and that L.T. should be immediately returned to the rightful custody of Respondent.

Respondent relies on two pieces of evidence to support her motion. First, she submits a report from Patricia J. Hale, a handwriting expert, concluding that someone forged the signatures of Respondent on five documents. Resp’t Ex. A, ECF No. 76-1. The documents are not attached to the motion but are described as “Marriage Notification in Japanese Language,” “Single Affidavit For Marriage of: Sarah Margaret Lael dated 3-19-2018”; “Marriage Declaration for One Person in Japanese Language,” “Divorce Notification in Japanese Language,” and “SunTrust Business Account Signature Card dated approx. December 2015 / January 2016.” Id. Second, Respondent submits an affidavit from Kanayo Okai, who states that she is an attorney licensed to practice law in Japan who practices primarily in the area of family law. Resp’t Ex. B, ECF No. 76-2. Ms. Okai states that under Japanese law, “the mother has sole custody and responsibility when children are born to unmarried

parents.” Id. She cites a Japanese law stating, “A father shall only exercise parental authority with regard to a child of his that he has affiliated if both parents agree that he shall have parental authority.” Id. She states that according to this law, “in principle, the mother has sole custody of a child born out of wedlock, but if the father acknowledges paternity, the father can be granted sole custody through mutual agreement between the parents.” Id. Ms. Okai states that this was the state of the law in Japan as of 2022 and remained so as of her August 6, 2025, affidavit. Id. II. DISCUSSION Respondent seeks relief under Rule 60(b) of the Federal Rules of Civil Procedure. Rule 60(b) provides: On motion and just terms, the court may relieve a party or its legal representative from a final judgment, order, or proceeding for the following reasons:

(1) mistake, inadvertence, surprise, or excusable neglect; (2) newly discovered evidence that, with reasonable diligence, could not have been discovered in time to move for a new trial under Rule 59(b); (3) fraud (whether previously called intrinsic or extrinsic), misrepresentation, or misconduct by an opposing party; (4) the judgment is void; (5) the judgment has been satisfied, released, or discharged; it is based on an earlier judgment that has been reversed or vacated; or applying it prospectively is no longer equitable; or (6) any other reason that justifies relief.
