How Overstaying in Japan Gets Discovered: Police Stops, Tip-Offs, and Everyday Paperwork

If you are living in Japan after your period of stay has expired, there is one question that tends to occupy every day: when and where will this come to light. The commute, the supermarket, the school run, all of it happens alongside the fear of being stopped by a police officer. In practice, overstaying (fuho zanryu, unlawful residence) comes to light through more than one route. Some people report themselves to the Immigration Services Agency. Others are discovered through a police stop, through contact between an employer or a public office and immigration, or through an investigation by immigration officers. This article sets out the main routes of discovery under the Immigration Control and Refugee Recognition Act (Immigration Control Act), and explains how the route matters for the procedure that follows and for the day you may next enter Japan.

One note on citation. Japanese statutes number their sub-items with kana characters. In this article they appear as イ, ロ, ハ, ニ, ホ, ヘ, corresponding to (a), (b), (c), (d), (e), (f).

How does the government usually find out about an overstay

There are broadly five entry points. First, the person reports voluntarily at a regional immigration services bureau (shutto shinkoku, voluntary appearance and self-report). Second, detection by immigration control officers. Third, an arrest or a police stop that leads to the discovery. Fourth, an immigration official learning of it in the course of some other procedure. Fifth, a report or item of information supplied by a related public body or by a private third party.

The Immigration Services Agency publishes collections of special permission to stay cases, and those collections record, case by case, which of these routes started the matter. That is not merely background detail. As set out below, the route determines which procedures remain available and how long the person must wait before entering Japan again.

Overstaying is also not only an administrative matter. Article 70, paragraph (1), item (v) of the Immigration Control Act penalises a person who remains in Japan beyond the period of stay without obtaining an extension or a change of that period. The statutory penalty is a kokinkei (custodial sentence) of up to three years or a fine of up to three million yen, or both (Article 70, paragraph (1), main clause). At the same time, Article 24, item (iv)(ロ) makes unlawful residence a ground for deportation. The criminal track and the administrative track run in parallel, and that structure underlies everything that follows.

What kinds of police encounters lead to discovery

Not unusual ones. The ordinary situations of daily life are where it happens: a bicycle registration check while riding, a traffic stop while driving a car or a motorcycle, a routine street inquiry near a station or in an entertainment district. Identification is requested, a residence card or a passport is produced, and the expiry of the period of stay becomes apparent.

What people often overlook is that the same thing happens when they are not the wrongdoer. Being injured in a traffic accident, going to the police after being defrauded or assaulted, calling the police during a domestic dispute, being questioned as a witness to someone else s case: all involve identity checks. The result is that many people do not report crimes committed against them and cannot ask for help when they are in danger. That is not merely a visa problem. It is a matter of the safety of the person and of their family.

Can an employer or a business relationship be the source of discovery

Yes, and employers have become increasingly careful about checking the validity dates on residence cards. A person who puts an overstayer to work faces the offence of promoting illegal work under Article 73-2. In addition, where the employer or the intermediary is a foreign national, Article 24, item (iii)-4 makes the conduct itself a ground for deportation. A criminal conviction is not a requirement of that provision.

On the individual side, if during a period when the person still held a status of residence they engaged exclusively in activity outside that status, questions may also arise under Article 70, paragraph (1), item (iv) and Article 24, item (iv)(イ). Once violations accumulate, the requirements for a departure order discussed below (Article 24-3, item (ii)) can no longer be met. That is why the facts should be organised early.

Can a government counter or a renewal procedure reveal an overstay

Any procedure that involves confirming identity may involve checking the period of stay: resident registration filings, health insurance, driving licence renewal, mobile phone and bank contracts, arrangements for a child s schooling. There are also cases in which a related public body contacts immigration and that becomes the trigger.

The point to be made here is that staying away from public counters does not solve anything. A life lived at a distance from medical care and schools damages the health and safety of the person and their family. It also produces a practical disadvantage later: when special permission to stay is sought, the evidence that shows a real life in Japan (medical records, school attendance, tax payments, community ties) will be thin. Years spent hiding do not accumulate into years of favourable material.

Can a tip-off from a private individual lead to enforcement

Yes. Neighbours, colleagues, former partners, and people on the other side of a financial or workplace dispute all form part of the immediate social circle from which information can be passed on. The Immigration Services Agency operates a channel for receiving information, and information received may become the trigger for a violation investigation under Article 27.

The assumption that nothing will happen because nobody has been told is, in reality, fragile. Discovery through information disclosed when a relationship breaks down tends to arrive suddenly, at a moment when no preparation has been made. Not being able to choose the timing of discovery is the central risk of waiting.

How much does the route of discovery change the outcome

A great deal. If the person ultimately leaves Japan, the waiting period before they may enter again is divided by statute into one year, five years, or ten years.

The departure order system (Article 24-3) is available where the person satisfies all five of the following requirements.

• Item (i): (イ) before the start of a violation investigation under Article 27, the person voluntarily appeared at an immigration services office with the intention of leaving Japan promptly; or (ロ) after the start of a violation investigation but before receiving the notice under Article 47, paragraph (3), the person stated to an immigration inspector or an immigration control officer that they intend to leave Japan promptly.
• Item (ii): the person does not fall under any of Article 24, items (iii) through (iii)-5, item (iv) sub-items ハ through ヨ, item (viii) or item (ix).
• Item (iii): after entering Japan, the person has not been sentenced to a kokinkei (custodial sentence) for offences under the Penal Code chapters on breaking into a residence, counterfeiting of currency, documents, securities and electromagnetic records of payment cards, gambling, homicide, injury, unlawful capture and confinement, kidnapping and abduction, theft and robbery, fraud and extortion, and stolen property; offences under Articles 1, 1-2 and 1-3 of the Act on Punishment of Physical Violence and Others; offences under the Act for Prevention of Theft and Others; offences under Articles 15 and 16 of the Act on Prohibition of Possession of Special Picking Tools; offences under Article 2 and Article 6, paragraph (1) of the Act on Punishment of Acts Causing Death or Injury by Driving a Motor Vehicle; or the offence under Article 22 of the Act on Prevention of Disposal of Stolen Specified Metal Products.
• Item (iv): the person has not previously been deported from Japan and has not previously departed under a departure order issued pursuant to Article 55-85, paragraph (1).
• Item (v): the person is expected to leave Japan promptly with certainty.

Where a departure order is issued, the supervising immigration inspector orders prompt departure and fixes a departure deadline within a period not exceeding fifteen days (Article 55-85, paragraph (1)), and may attach conditions such as restrictions on residence and area of movement (paragraph (3) of the same Article). Unlike deportation proceedings, this procedure does not presuppose detention.

The period during which landing is denied then breaks down as follows.

• A person who departed under a departure order: Article 5, paragraph (1), item (ix)(ホ), one year from the date of departure.
• A person falling under Article 24-3, item (i)(ロ), that is, a person who expressed the intention to depart after the violation investigation had begun, who departs under a departure order and who then seeks to engage in the activities of a temporary visitor: Article 5, paragraph (1), item (ix)(ヘ), five years from the date of departure.
• A person who was subject to deportation but received a decision under Article 52, paragraph (5) and departed voluntarily within the deadline, other than for the purpose of a temporary visit: Article 5, paragraph (1), item (ix)(ロ), one year from the date of departure.
• A person who was deported and who had no prior record of deportation or of departure under a departure order: Article 5, paragraph (1), item (ix)(ハ), five years from the date of deportation.
• A person who was deported and who already had such a prior record: Article 5, paragraph (1), item (ix)(ニ), ten years from the date of deportation.
• A person deported on grounds falling under Article 24, item (iv), sub-items オ through ヨ (入管法24条4号オからヨまで): Article 5, paragraph (1), item (x), with no fixed period.

Where discovery comes through enforcement, other violations often accumulate so that item (ii) or item (iii) is not satisfied, or a prior record of deportation or of a departure order means item (iv) is not satisfied. The departure order route then disappears altogether, leaving deportation with five years (item (ix)(ハ)) or ten years (item (ix)(ニ)). A difference measured in days, before or after the start of a violation investigation, becomes a difference measured in units of five years.

What does it achieve to come forward before being detected

Two things. The first is the statutory branching just described. The second is the assessment made when special permission to stay is considered.

Article 50, paragraph (5) provides that the Minister of Justice is to consider the reasons for wishing to remain, family circumstances, conduct, the circumstances of entry into Japan, the length of residence in Japan and the legal status held during that time, the facts constituting the ground for deportation, and the need for humanitarian consideration, and in addition is to consider domestic and international conditions, the effect on unlawful residents in Japan, and other circumstances. The Guidelines on Special Permission to Stay, revised in March 2024 and in force from 10 June 2024, state expressly that the fact that the foreign national voluntarily appeared at a regional immigration services office in order to report their unlawful residence is taken into account as a positive factor. Prolonged unlawful residence, by contrast, is assessed as a negative factor. The Guidelines position special permission to stay as an exceptional and discretionary measure granted to a foreign national who is to be deported, so favourable circumstances have to be built up one at a time.

The same logic applies on the criminal side. The statutory penalty does not vary with the length of the overstay. What varies is the prosecutor s choice of disposition and the range of sentence. How long the unlawful state was allowed to continue, whether the person came forward, and whether the basis of their life and family relationships is clear all bear on that. Cases involving a short period, a voluntary appearance and a clear pattern of daily life tend towards lighter dispositions; cases involving a long period, illegal work, or additional violations such as forged documents tend towards heavier ones. The range varies from case to case, and any forecast has to be made individually.

The police or immigration already know. Is it too late

It is not too late. Even where departure is the realistic path, Article 24-3, item (i)(ロ) covers a person who states an intention to depart after the violation investigation has begun, provided the notice under Article 47, paragraph (3) has not yet been received. It should be noted, however, that where such a person departs under a departure order and then seeks to engage in the activities of a temporary visitor, Article 5, paragraph (1), item (ix)(ヘ) sets the period at five years.

Where the wish is to remain in Japan, arguments and evidence are built up at each stage of the deportation procedure: violation investigation (Article 27 and following), a written detention order (Article 39) or a decision on supervisory measures (Article 44-2, paragraph (7)), examination by an immigration inspector (Article 45 and following), a finding (Article 47, paragraph (3)), a request for a hearing (Article 48), the determination of a special inquiry officer (Article 48, paragraph (8)), a filing of objection with the Minister of Justice (Article 49), and the decision, leading either to special permission to stay (Article 50) or to the issuance of a written deportation order (Article 51).

An application for special permission to stay may be made by a foreign national detained under a written detention order or subject to a decision on supervisory measures (Article 50, paragraph (2)). Once a written deportation order has been issued, no application may be made (Article 50, paragraph (3)). Most overstay cases are decided within Article 50, paragraph (1), item (v), which covers other circumstances in which the Minister finds that residence should specially be permitted. The important point is that a case involving unlawful residence alone (Article 24, item (iv)(ロ)) does not fall within the heightened requirement in the proviso to Article 50, paragraph (1), namely the requirement that permission be granted only where there are special circumstances such that refusing to permit residence would be found to lack humanitarian consideration. That is a favourable feature of such cases. Conversely, a custodial sentence of indefinite duration or of more than one year to be actually served brings that proviso into play and makes the outlook considerably harder. That is precisely why work to lighten the criminal disposition and work to obtain special permission to stay must be designed together from the very first step.

About our office

Funado International Law Office (3F Fuse Building Main Wing, 3-4-10 Takada, Toshima-ku, Tokyo) concentrates on criminal defence for foreign nationals and on immigration procedures, with a client base centred on Chinese nationals. Daisuke Matsumura, the attorney in charge, is a member of the Dai-ichi Tokyo Bar Association (registration number 59077, admitted in 2019).

Three features characterise how the office works. First, Mr Matsumura handles every stage personally, from the first detention visit through to the close of trial. Clerical staff and junior lawyers do not take over on his behalf. Second, a dedicated Chinese interpreter experienced in cases involving foreign nationals is based at the office. For other languages, an interpreter is arranged according to the case. Having an interpreter who acts for the client, separately from the interpreter designated by the investigating authorities, matters greatly where a fine shade of meaning in a statement can decide the outcome, and the same is true of immigration interviews. Third, renewal or change of status of residence after the criminal process ends is handled on a one-stop basis together with an affiliated administrative scrivener.

Two matters handled by the office may be useful as illustrations.

In the first, special permission to stay, regarded as difficult to obtain, was secured in a single set of proceedings. The client had come to Japan as a tourist and had a child with a Japanese woman, but lost his status of residence and was arrested and prosecuted for unlawful residence. Marriage and acknowledgement of paternity had not been completed and were initially not accepted by the authorities. Mr Matsumura negotiated with the authorities from a constitutional standpoint, secured the marriage and the acknowledgement, and conducted the defendant examination and witness examination with the immigration prosecution squarely in view. Favourable evidence was gathered in circumstances where almost no official documents were available from the country of nationality, and past permission cases of the immigration authorities were analysed. Special permission to stay was granted.

In the second, a woman wrongly accused of promoting illegal work faced deportation. Against the established practice that intent and negligence are not required for a ground of deportation, proceedings were brought to test the reach of the principle of individual responsibility, and were pursued through to the appellate stage. Special permission to stay was subsequently granted by the immigration authorities.

The first consultation is free of charge. Fees are quoted according to the case. It is entirely acceptable to come in before deciding anything. We begin by working out together which route of discovery your situation falls under, whether there is any record of deportation or of criminal disposition, and what material can be used to show the reality of your life in Japan.

Closing

You do not choose the route by which an overstay is discovered. The only thing you can choose is whether to act before that happens. Whether a violation investigation has already begun is, in statutory terms, the difference between one year and five, or between five years and ten. Even if it is not yet clear which route your situation falls under, coming to us early leaves far more options open.

This article is a general explanation. For an individual case, please consult a lawyer directly. The past matters described here rest on their own particular circumstances and are not a guarantee of a similar outcome.
