Payment deadline calculator
Two deadlines: 10 days from the notification, and 7 days for provisional payment from the citation. Different anchors, so two fields.

The day you received the written notification (Road Traffic Act Art. 128(1)).
The day you were cited at the roadside. The provisional-payment clock runs from this one (Art. 129(1)).

Deadlines
Two deadlines, counted from two different events
A blue ticket carries two deadlines of different kinds. Both are counted from the day AFTER something happened — but not the same something. One date field cannot produce both.
Payment after notification
10 days
counted from the day after the written notification (tsūkoku)
Road Traffic Act, Art. 128(1)
Provisional payment
7 days
counted from the day after the roadside citation (kokuchi)
Road Traffic Act, Art. 129(1)
Instalments are never allowed
Payment of a hansokukin may not be made in instalments. The Cabinet Order states no exception.
Cabinet Order, Art. 51(4)
Two clocks
Why the form asks for two different dates
A blue ticket does not produce one deadline. It produces two, counted from two different events — which is why this page has two date fields rather than one field and a dropdown.
The first event is the roadside citation (告知, kokuchi): the moment an officer hands you the slip. The second is the written notification (通告, tsūkoku) that follows separately, by post. They are not the same day, and a window counted from the wrong one is wrong by however many days separated them.
The provisional-payment window of 7 days runs from the day after the citation. The payment window of 10 days runs from the day after the notification. Both count from the day AFTER their triggering event, never from the event itself — so the day you were stopped is not day one.
Which one applies
One window is optional; the other is the one that matters
Provisional payment (仮納付, kari-nōfu) is something a driver MAY do before the formal notification has issued at all. It is an option the Act offers, not a step you are required to take, and letting it pass is not the same as missing the payment deadline.
The post-notification window is the one that decides whether the case stays on the blue-ticket track. When the rest of this site says "the deadline" without qualifying it, that is the one it means.
So: if you are holding a roadside slip and nothing has arrived by post, you are inside the first window. Once a written notification arrives, the second window is running, and it is counted from that document rather than from the original stop.
One rule, no exceptions
The amount cannot be split
Whichever window applies, the amount is paid in full or it is not paid. Instalments are not permitted, and the Cabinet Order states no exception, no hardship route, and no discretion for the office receiving the money.
That is worth saying plainly, because a part-payment made in good faith does not buy partial credit or extra time. It is not a smaller payment — it is a payment the provision does not recognise.
This page gives the dates and that rule, because those are what the statutes state. Where and how to physically hand over the money is not sourced here, and the instructions printed on your own notice are the authority for it.
What this system does not cover
What this site does not answer, and why
These are content, not gaps. Each is a bounded statement that a NAMED instrument does not contain something — never a claim that "the law is silent".
Death and injury by driving is a different Act
The Act on Punishment of Acts Causing Death or Injury by Driving was amended by the same Act that amended the Road Traffic Act (Act No. 52 of 2026), but its offences and penalties are its own. This site has not transcribed them. A case involving death or injury is outside this calculator.
- 自動車運転死傷行為処罰法, in force 2026-07-21
The payload's own note, verbatim (an instrument name in 【 】 is this site's)
自動車運転死傷行為処罰法 (death/injury-by-driving offences) is vendored in the corpus and was amended by the SAME act that amended 道路交通法 on 2026-07-21 (令和八年法律第五十二号) — but its own offence/penalty structure is a SEPARATE instrument and is not transcribed into this payload.
The summary-trial procedure is a different Act
The Summary Trial Procedure Act for traffic cases governs HOW a minor traffic case is disposed of. It is procedural and carries no amount of its own, so it is not modelled here. Its ceiling and this offence's own ceiling are two different figures.
- 交通事件即決裁判手続法, in force 2026-05-21
The payload's own note, verbatim (an instrument name in 【 】 is this site's)
交通事件即決裁判手続法 (the summary-trial PROCEDURE for minor traffic offences) is vendored — procedural, carries no rate figure of its own, and is not modelled here.
Minimum speeds are not transcribed
【道路交通法施行令】Minimum speeds are set by Cabinet Order Art. 27. Arts. 11 and 12 only point at it ("the next Article" / "the preceding Article"); the figure itself is not within what this site transcribed. It was read, and not taken.
- 道路交通法施行令 (Cabinet Order No. 270 of 1960), 第二十七条 — consolidation in force 2026-05-21
The payload's own note, verbatim (an instrument name in 【 】 is this site's)
最低速度 (minimum speed, expressway mainline — 第二十七条 and neighbours, referenced in passing by 第十一条/第十二条's own cross-references) is a separate figure this fixture did not extract.
Not every Chapter 8 article is covered
【道路交通法】Chapter 8 of the Road Traffic Act (Arts. 117–122) holds more articles than the ones this site joined to the hansokukin ceilings. Only the articles that Appended Table 2's own rows name are transcribed. Arts. 117 and 122, and Arts. 118-2 and 118-3, are referenced by no ceiling row and are not transcribed.
- 道路交通法 (Act No. 105 of 1960), 第八章 罰則（第百十七条―第百二十二条） — consolidation in force 2026-07-21
The payload's own note, verbatim (an instrument name in 【 】 is this site's)
Chapter 8 (第百十七条～第百二十二条) has MORE articles than the eight this fixture joined to jpFinesCeiling. Only the ones 【道路交通法】別表第二's own rows reference by locator are transcribed (第百十八条, 第百十八条の二/三 excluded, 第百十九条, 第百十九条の二の四, 第百十九条の三, 第百二十条, 第百二十一条); 第百十七条 and 第百二十二条 (and 第百十八条の二/三) are not referenced by any 反則金 ceiling row and are not transcribed here.
For a juvenile, the family court sets the amount
【道路交通法】Under Road Traffic Act Art. 130-2(1), second sentence, where a case reaches a family-court hearing the amount is set by that court within the Act's own Appended Table 2 ceiling. There is no fixed schedule figure to read off, so this site states none.
- 道路交通法 (Act No. 105 of 1960), 第百三十条の二第一項後段 — consolidation in force 2026-07-21
The payload's own note, verbatim (an instrument name in 【 】 is this site's)
第百三十条の二第一項後段: when a juvenile's case reaches a family-court hearing, the court MAY order 反則金 payment on its own schedule, and the AMOUNT is then set by the family court itself — "その反則金の額は、第百二十五条第三項の規定にかかわらず、【道路交通法】別表第二に定める金額の範囲内において家庭裁判所が定める額とする" — within 【道路交通法】別表第二's ceiling, but not read off any fixed schedule figure this fixture can transcribe as a number.
The mitigated floor is not stated
Penal Code Art. 15 carries a proviso: on statutory mitigation grounds a court CAN sentence below the floor. This site states only the un-mitigated floor and does not model when mitigation applies.
- Penal Code, Art. 15, proviso
Expressway mainline default speeds are out of scope
The default speed on an expressway mainline is set by Cabinet Order Art. 27, which this site has not transcribed. The general-road figure is never reused for it. On an expressway, enter the posted limit.
- Cabinet Order, Art. 27
No alcohol or BAC classification
This site's calculators do not classify alcohol readings. There is no verified threshold table here to drive one, and producing a number without it would be the opposite of accuracy.
- Not transcribed into this site's payload
No "will I lose my licence" prediction
Suspension and revocation from accumulated points are set by the Cabinet Order's Appended Table 3 together with Road Traffic Act Art. 103. Both were read; neither is modelled. There is no such calculator here.
- Cabinet Order, Appended Table 3 / Road Traffic Act, Art. 103
No foreign-licence or visitor-specific rules
Nothing in the material this site read carries rules specific to foreign licences or cross-border drivers. This English bundle is a translation of the same claims and makes no additional ones.
- Not transcribed into this site's payload
Where to physically pay is not stated here
What the statutes give is the deadline and the no-instalments rule. Counters, banks and opening hours are not sourced, so they are not written. Follow the instructions printed on your own notice.
