The Four Divorce Paths

The Four Divorce Paths in Japan run from a paper filing at the ward office to a full court trial, and which one applies to you turns mostly on whether both spouses agree.¹² Roughly nine in ten divorces end at the first path, mutual consent (as of 2026-02-26), while the rest move through family-court mediation and, rarely, a judge's decision or trial.¹³

Overview

Japan sorts every divorce into one of four paths: divorce by agreement (kyogi rikon), divorce by mediation (chotei rikon), divorce by family-court decision (shinpan rikon), or divorce by court judgment (saiban rikon).¹ The structure is national, set by the Civil Code and the Domestic Relations Case Procedure Act, so the ladder itself works the same in every prefecture.¹

The ladder works by consent. Agreement needs both spouses to say yes and file a notification at the municipal office.² Mediation and litigation can each be started by one spouse alone, but then the burden shifts to persuading a conciliation committee or proving statutory grounds to a judge.² Statutory grounds matter decisively mainly in court judgments, though breakdown allegations surface in mediation and negotiation too.¹

How the four paths relate

Think of the four paths as steps you climb only as far as disagreement forces you. Mutual consent ends the marriage by paperwork.⁴ Failed agreement leads to mandatory mediation.¹³ Failed mediation leads to a judge's decision or, as a last resort, a full trial.²⁴

Mutual-Consent Divorce (Kyogi Rikon)

The 協議離婚 (kyogi rikon, "divorce by agreement") is the simplest and most common form of divorce in Japan.⁴ Both parties agree to end the marriage and register the divorce at their local city or ward office, with no court involvement unless disputes arise.⁴

The divorce takes effect by filing a 離婚届 (rikon todoke, "divorce notification form") with the relevant municipal authority.¹ No service of process is required, and no reason must be stated: Civil Code Article 763 provides simply that a husband and wife may divorce by agreement.¹² No specific grounds are required for this path.⁴

Roughly nine in ten divorces conclude this way without substantive judicial determination (as of 2026-02-26; confirm current figures with the family court system).¹ A second professional source likewise reports almost 90% completed by submitting a form at the city office (as of 2025-03-19).³

Settle money and custody terms before you sign

The notification ends the marriage on filing, but it does not divide property or fix support. Negotiate those terms first, because signing away your leverage and sorting out the rest later is a weak bargaining position.¹³

What the filing settles and what it does not

The filing settles one thing: the marriage ends. Property division can be claimed independently after the divorce is finalized or as an ancillary claim in divorce litigation, which confirms the notification itself does not divide assets.¹

Child arrangements work the same way. Parents do not necessarily decide access issues at the time of divorce, and support amounts and visitation are often settled upon or after the divorce.³ A private agreement on child support is valid as a contract, but it needs a notarized deed with an enforcement clause or a court mediation record before it can be enforced.¹

Mediated Divorce (Chotei Rikon)

When couples cannot agree on the divorce itself or on issues such as custody, asset division, or support, the next step is 調停離婚 (chotei rikon, "divorce by family-court mediation").⁴ A neutral mediator helps both parties negotiate toward terms they can both accept.⁴

Mediation is not optional in contested cases. Where the parties cannot agree, an application for divorce mediation must be filed with the 家庭裁判所 (katei saibansho, "family court"), and this step is mandatory under Article 257 of the Domestic Relations Case Procedure Act before any litigation can begin.¹ In mediation, the court serves a copy of the petition on the respondent.¹

Mediation commonly runs six to eight months as a general indication, with duration varying by the issues in dispute and the degree of conflict (as of 2026-02-26; confirm current figures with the family court).¹ About half of cases settle by agreement during mediation, and those settled cases average about 5 months (as of 2025-03-19).³ If mediation fails, either party may proceed to file litigation.³

How mediation sessions run

A conciliation panel of one judge and two mediators, mainly two non-lawyer mediators (one male and one female), conducts the sessions.³ The committee hears each side's arguments and allegations and proposes alternatives to resolve the disagreement.² Agreement is still required at this stage: the committee can propose, but it cannot impose.²

Foreign residents are not shut out of this path. Foreigners in Japan can apply for divorce mediation at the family court, in principle at the court with territorial jurisdiction over the defendant's domicile.³

Arbitrated Divorce (Shinpan Rikon)

The 審判離婚 (shinpan rikon, "divorce by family-court decision") covers the narrow case where mediation almost reaches agreement but cannot quite close the gap. A family-court judge then issues a decision to finalize the divorce.⁴

This type is less common than the other three and usually follows unresolved disputes left over from mediation.⁴ Where conciliation fails, the law offers two court-driven exits: a determination (shinpan) or a full trial (saiban), with shinpan serving as the lighter of the two.² Adjudication sits alongside mediation as a family-court route, distinct from divorce by court judgment.¹

Litigated Divorce (Saiban Rikon)

The 裁判離婚 (saiban rikon, "divorce by court judgment") is the last resort. One party files a lawsuit, presents evidence, and argues before a court, a process that is lengthy, costly, and emotionally taxing.⁴

In litigation, the complaint must be formally served on the other spouse, or served by publication where the respondent's whereabouts are unknown.¹ Cases take approximately one to two years as a general indication, varying with the issues and the level of conflict (as of 2026-02-26; confirm current figures with the family court).¹

There is no statutory minimum separation period, but the length of separation weighs heavily in proving irretrievable breakdown (as of 2026-02-26).¹ A separation of roughly five years generally creates a strong inference that the marriage has broken down, though recent practice leans toward shorter periods.¹ Claims brought by the spouse mainly at fault are restricted in principle, but a court may still grant the divorce where breakdown is irretrievable and doing so does not offend good faith (Supreme Court, 2 September 1987).¹

Where a party lives abroad, service runs through international judicial assistance including the Hague Service Convention and can take several months or more than a year in practice.¹

The five statutory grounds

Civil Code Article 770(1) permits either spouse to file suit for divorce only on five grounds: unchastity, abandonment in bad faith, three or more years of unclear life-or-death status, severe mental illness with no prospect of recovery, or any other grave cause making continuance of the marriage difficult.² The same five appear in every professional summary of the statute.¹⁴³

Ground (Article 770)	What it covers
(i) Act of unchastity	不貞行為 (futei koui): a sexual relationship with someone of the opposite sex other than the spouse, generally adultery; same-sex conduct falls under the grave-cause ground instead2
(ii) Abandonment in bad faith	悪意の遺棄 (akui no iki): failing without legitimate reason in the duty of mutual support, such as withholding living expenses or locking a spouse out; work-related separation does not qualify2
(iii) Unclear life or death for 3+ years	Whereabouts and survival completely unknown; mere loss of contact while the residence is traceable does not qualify2
(iv) Severe mental illness	Illness with no prospect of recovery; curable conditions such as depression are generally insufficient, and courts require proper post-divorce living and treatment arrangements for the ill spouse2
(v) Other grave cause	The catch-all most cases are actually argued under, requiring irretrievable breakdown judged on intent to continue plus objective facts such as prolonged separation12

The catch-all covers conduct such as physical violence or psychological abuse, in-law abuse a spouse abetted, sexual incompatibility or refusal, addiction, extended imprisonment, excessive religious activity, and gambling or wasteful spending.² Personality differences alone are usually insufficient.²

Two qualifications apply. Even where one of the first four grounds is established, the court may dismiss the suit if continuing the marriage still looks reasonable on all the circumstances (Article 770(2)).² And practitioner sources report that the severe-mental-illness ground was removed under the Civil Code reform effective 1 April 2026 (as of 2026-02-26).¹

Which Path Applies to Your Situation

Consent decides the starting point. If both spouses agree, the municipal-office filing ends the marriage quickly and cheaply.²⁴ If one spouse will not agree, that route is closed entirely, and the spouse seeking divorce must start with family-court mediation before any trial is possible.¹²

Situation	Path	Consent needed	Venue
Both spouses agree	Kyogi rikon	Yes, both signatures	Municipal office24
Disagreement on divorce or terms	Chotei rikon	No, one spouse can file	Family court13
Mediation nearly agrees but stalls	Shinpan rikon	No, judge decides	Family court24
Mediation fails and grounds exist	Saiban rikon	No, court can dissolve	Court trial14

At least one statutory ground must be proved for a court-ordered divorce, while no grounds are needed where the parties mutually agree.³ Foreign nationals should also weigh compatibility: the Japanese procedure must be compatible with the home country's requirements for recognizing the divorce.³ Some foreign jurisdictions do not recognize paper-only divorces for lack of judicial oversight, so confirm with home-country authorities before relying on a ward-office divorce abroad (as of 2026-02-28).⁵

Good to know

A signed rikon todoke ends the marriage even without a property agreement

The notification procedure effects the divorce on filing, while property division can be claimed independently afterward and support or access terms are often left undecided at divorce.¹³ That sequence means signing first and negotiating later weakens your leverage. Put financial and custody terms in writing before either spouse signs.

Mediation must come before litigation in contested cases

A contested divorce cannot skip straight to trial. Mediation is a mandatory prerequisite under Article 257 of the Domestic Relations Case Procedure Act, and it commonly runs six to eight months before any lawsuit even begins (as of 2026-02-26).¹ Budget that time from the start rather than treating trial as the opening move.

A ward-office divorce may not count as a divorce abroad

Home-country recognition of a paper-only divorce varies by nationality. Some foreign jurisdictions do not recognize divorces without judicial oversight, so a couple legally divorced in Japan may still count as married elsewhere (as of 2026-02-28).⁵ Confirm recognition with your home-country authorities before remarrying or filing taxes as single abroad.
