The Kyogi-Divorce Form and Its Limits
The Kyogi divorce form ends a marriage in Japan the moment a ward office accepts it, with no court hearing when both spouses agree.12 That single sheet looks deceptively complete, yet it settles almost nothing about money or children beyond one custody line.
Procedures, fees, and requirements can change. Confirm current details at the Ministry of Justice divorce registration guidance and your filing municipal office. This article is general information, not legal, tax, or immigration advice; for your specific case, consult a licensed family-law specialist (bengoshi), especially where minor children, contested property, suspected forged signing, or cross-border recognition are involved.
Overview
A 協議離婚 (kyogi rikon, "divorce by mutual consent") is a divorce effected when husband and wife agree, sign the notification, and submit it to a local government office.1 The notification itself is the 離婚届 (rikon todoke, "divorce notification form").2
About 86 percent of Japanese divorces in 2021 used this path, with mediation near 10 percent and litigation at 1 to 2 percent (as of 2021; confirm current shares with the Ministry of Health, Labour and Welfare vital statistics).3 The MOJ English divorce hub covers the surrounding issues of custody, support, contact, and property, and scopes its international guidance to couples where one spouse is Japanese and habitually resident in Japan.4

What the Rikon Todoke Requires
The form has four moving parts: two signatures, two witnesses, a custody and name section, and a counter filing. Each part below states the national rule first, then the ward-level variation.
Both spouses sign
Kyogi divorce requires the agreement of husband and wife, and both sign the notification form.1 Seal-stamping on family register notifications is optional since the September 1, 2021 reform, so a signature alone suffices.5
Only one party needs to carry the signed form to the counter. Both spouses do not need to appear together if the form was properly signed beforehand.6
Two adult witnesses
A kyogi filing requires the signatures of two adult witnesses, and seal-stamping by witnesses is optional.2 The adult age in Japan is 18, so witnesses must be 18 or older. Confirm any ward-specific identity check with your filing office.2
Witnesses can be friends, colleagues, or family members.3 They attest to the filing, not to the fairness of any property or custody terms.
Because only one spouse needs to visit the counter, a signed form left in the house can be submitted by the other spouse alone. If you already signed under pressure or suspect forgery, file the non-acceptance petition described below before the form reaches a counter.6
Custody and post-divorce name fields
親権 (shinken, "parental authority") is the authority and responsibility to care for, educate, and manage the property of a child.7 Married parents exercise it jointly, and divorcing parents must decide who holds it after divorce.7
The holder is set by agreement between the parents after consultation about the child's future and which parent suits care, education, and property decisions.8 The rikon todoke records that choice on its custody line for minor children, but it does not fix support amounts, visitation, or property shares.81
Surname handling after divorce uses a separate notification filed alongside or after the divorce. Confirm the exact form and deadline with your ward office, since the specific day-count rule was not verified to a primary source for this article.
Where and how to file, and when it takes effect
File the completed notification at the municipal office of the filer's registered domicile or current location.2 That office can be a city, ward, town, or village office. Bring identity documents such as a driver's license or passport, since staff verify the filer at the counter.2
Form paper is picked up at the municipal office, and the MOJ publishes entry-example PDFs by surname and custody pattern.2 Filing the notification itself carries no fee (as of 2026-09-08; confirm current figures with your filing municipal office).2
| Item | Amount | As of | Notes |
|---|---|---|---|
| Rikon todoke filing fee | ¥0 | 2026-09-082 | No fee; form paper picked up at the municipal office |
The divorce takes legal effect when the office accepts the filing, so a correctly completed kyogi filing is same-day effective.21 Kyogi filings can be submitted at any time, while court-route filings carry a 10-day post-judgment window that does not apply here.2
Reception hours, including nights and weekends, are set per municipality rather than by national rule.2 If an office refuses acceptance, the filer may appeal to family court under Family Register Act Article 122.2
The filing sequence looks the same whichever eligible office you choose:

What the Form Does Not Settle
Filing the form ends the marriage. Everything about money and ongoing child arrangements lives outside it unless you put it in writing elsewhere.
Property, support, and custody beyond the one-line entry
財産分与 (zaisan bunyo, "distribution of property") means dividing property acquired during the marriage between the divorcing couple.9 Property agreed at divorce can change hands then, and further distribution may still be claimed within two years of the divorce.10
Divorcing parents should decide the child-support amount, payment period, timing, and method such as the remittee bank account, in good faith so payment runs smoothly.11 That agreement should be written rather than left as an oral promise, and the MOJ points to its model agreement form as an aid.11
Child-support amounts are basically set by negotiation, with the court-published Calculation Table as a non-binding reference.12 The rikon todoke alone does not settle property division, support enforcement, visitation, or pension splitting, so couples who file without settling those terms leave them to later negotiation, mediation, or court.1
The separate divorce agreement
Couples should determine money issues such as asset division and compensation, plus child issues such as support and visitation, and put the agreed matters in a printed divorce agreement.1 Practitioner guidance describes emotional filings without full discussion as a documented failure pattern, and a detached review helps surface reasonable support and compensation levels.1
Write the agreement before or beside the form, not weeks later. Once the marriage has ended, leverage to negotiate drops and every term costs more time to reopen.
Notarized koseishosho for enforceability
In preparation for non-payment of child support, preparing a notarized document with execution-approval wording containing the agreed matters is recommended.1 With a qualifying notarized agreement, a compulsory-execution procedure in district court is available. Without one, a family-court petition for conciliation or other proceedings is the fallback, and the same applies when using the MOJ model agreement.13
A family-court mediation record carries the same legal weight as a court ruling when mediation succeeds.3 That route helps couples who cannot agree privately, but it takes months where a pre-filing written agreement takes days.
Blocking a Non-Consensual Filing
Japan checks the form on its face, not the intent behind each signature. The non-acceptance petition exists for exactly that gap.
How to file the fu-juri petition
The non-acceptance system prevents acceptance of a notification not based on the person's own intention.14 Once filed, the office rejects a covered filing unless it confirms the petitioner appeared in person.14
Covered notifications include kyogi divorce notifications alongside marriage, adoption, dissolution of adoption, and acknowledgment filings.14 Either husband or wife may file for a kyogi-divorce block.14
File in person at the municipal office of your registered domicile or current location, since submission by mail is generally not accepted.14 Bring the non-acceptance form available at the ward family-register counter plus photo ID such as a driver's license, passport, or My Number Card.14
Outside register-counter hours, night and holiday counters accept the form only with government-issued photo ID.14 The filing is held as a deposit and backdated to the submission date once register staff confirm it on the next business day.14
The petition takes effect from the date and time submitted and remains effective indefinitely until withdrawn, with no validity period (as of 2026-04-07; confirm current handling with your municipal office).14 The statutory basis cited by practitioner guidance is Family Register Act Article 27-2.6
The protection flow looks like this:
What blocking does and does not do
A signed-but-undelivered form can be filed by the other spouse alone, and forged-signature filings have been accepted and annulled only after months of family-court proceedings.36 That delay is the reason to file the block early rather than after a surprise.
The block does not stop a judicial divorce through mediation, adjudication, or litigation filed through the court itself, and it does not undo an already-accepted filing.6 If the divorce was already accepted, the route is a family-court mediation to confirm the invalidity of the consensual divorce, not a ward-office reversal.6
U.S. citizen parents have been advised they may file the petition at the municipal office of the Japanese parent's residence or registered domicile where a surreptitious filing or sole-custody declaration is feared (as of 2026-09-08).6

Good to know
File the money agreement before the form when children or property are involved
Filing the rikon todoke ends the marriage on acceptance but leaves money and child terms unsettled.111 Negotiating support, property, and visitation first and writing them down avoids post-divorce conflict, since leverage to reopen terms drops once the divorce is final.
Without a notarized executory deed, an unpaid support promise requires a fresh court step before compulsory execution.131 With one, district-court execution is directly available. That paperwork choice decides whether enforcement can proceed directly or needs a fresh court step first.
Ward-office details vary, so confirm with your filing office
Which attachments beyond the witnessed form are needed, plus reception hours and night or weekend handling, differ by municipality.2 The MOJ directs filers to confirm with the filing office rather than assuming a neighbor ward's checklist applies.
Night and holiday fu-juri filings are deposit-only and need government photo ID.14 Inter-municipality confirmation delays can also force deposit handling until the next business day, so daytime filing at the register counter is the safer default.
A kyogi divorce may not count as a divorce back home
Some home countries do not recognize a Japanese extra-judicial divorce without further steps.3 Same-nationality foreign couples and Japanese-foreign couples face different applicable-law questions, so the recognition answer turns on nationality rather than on where the form was filed.
Practitioner sources describe Philippine law as requiring judicial recognition before the divorce takes effect there, and U.S. state-by-state treatment of non-judicial divorce as unsettled (as of 2026-09-08; confirm current requirements with your embassy or counsel).6 Report the divorce to your home country through your embassy or consulate where required, and take counsel before assuming remarriage capacity abroad.
Joint custody entries after the April 2026 reform need a date check
The 2024 Civil Code amendment introduces selective post-divorce joint custody effective April 1, 2026, with a joint-custody option on the rikon todoke custody field (as of 2026-09-08).6 Where parents disagree, practitioner guidance describes the family court as deciding on the child's welfare, with sole custody where abuse risk is shown.6
A unilaterally pre-filled custody choice is hard to revisit administratively once the filing is accepted.6 That timing risk is another reason to settle the custody line jointly and file the fu-juri block where a unilateral filing is feared.
