Does Toei Bus Issue a Delay Certificate? What to Do Instead

No page on the official site describes a delay certificate for Toei Bus

The bus is held up in traffic, and you reach the office after the start of work, or the classroom after first period has begun. At that point a reasonable thought occurs: railways hand out delay certificates, so could a bus give you one as well? A delay certificate (chien shomeisho) is a document a Japanese railway issues when its trains run behind schedule, and passengers hand it to an employer or a school as evidence that the lateness was not of their own making. For buses the short answer is this: as of September 2026, no page on the Tokyo Metropolitan Bureau of Transportation website describes a delay certificate for Toei Bus. Neither the frequently asked questions for Toei Bus nor the index of bus service information carries an entry for a document that certifies a delay.

The delay certificate page the Bureau publishes online states its scope plainly. It explains that certificates are posted line by line for trains on Toei Subway, the Toden Arakawa Line tram and the Nippori-Toneri Liner, and Toei Bus is not among them. The same pattern shows up in the Bureau's service information listings: the subway lines and the tram carry links to their delay certificates, while the Toei Bus entry offers only a link to the bus service information site.

One thing is worth adding for balance. The Bureau does not state that Toei Bus does not issue a delay certificate, either. What the published information supports is narrower: that no guidance for one can be found, and that there is no self-service mechanism for obtaining one online. The sections below look in turn at why rail and bus are treated differently, what you can do if you still need something in writing, and how to tell this document apart from another whose name is very nearly the same.

A rail delay certificate covers a line and a time band, not your particular train

Knowing what a rail delay certificate actually certifies makes it easier to see why buses sit outside the arrangement. The Bureau's page sets out the details. A certificate is posted when a delay of 5 minutes or more has occurred, and the delay is shown rounded up to the nearest 5 minutes. Postings are split into two time bands, from the first service until 10 a.m. and from 10 a.m. until the last service, and each one stays up for 35 days from the day it appears.

The most important point is stated explicitly on that page: the certificate shows the longest delay that occurred on a given line in a given time band, and it does not certify the delay of any individual train. It also says the certificate is not proof that the passenger traveled on that train at all. A rail delay certificate, in other words, is not a personal travel record. It is a published statement that on this line, in this time band, the delay reached this much at its worst.

Try to transplant that arrangement onto buses and it starts to strain. Trains on the same line run under much the same conditions, whereas buses on a single route can be delayed quite differently from one departure to the next and from one stretch of road to another. One bus can be caught in congestion and fall well behind while the one behind it catches a clear run and keeps to the timetable. A certificate expressed as the worst delay across a whole line would arguably be a poor likeness of what a bus service actually experienced. How delays arise in the first place, and how they spread, is covered in detail in why buses run late.

What you can do when you still need something in writing

None of that removes the real situation in which a school or a workplace expects an explanation for your lateness. The first thing worth doing is the least dramatic: find out what the recipient is actually asking for. Will nothing but a certificate on a set form be accepted, or is a self-reported note of the time and the route enough? If it is the latter, there is no need to go hunting for paperwork. Practice varies by recipient, which is why it is worth asking first.

With that settled, these are the details worth writing down. Whether you go on to make an inquiry or simply explain the situation yourself, having them to hand makes a considerable difference to how smoothly the conversation goes.

• The route number of the bus you boarded and the destination shown on the front
• The names of the stop where you boarded and the stop where you got off
• The departure time printed in the timetable and the time the bus actually left
• Anything you could see as the cause, such as congestion or an accident

As for who to ask, the Toei Transportation Customer Center handles inquiries about Toei transport in general. The number is 03-3816-5700 and it is open from 9 a.m. to 8 p.m., every day of the year (as of September 2026). Questions about fares and times are dealt with there as well. You can also approach the bus depot that operates the route you used; the list of depots is on the Bureau's Toei Bus depot directory.

Here is the honest caveat. No official guidance can be found that promises a document of any kind in response to an inquiry, so it would be unwise to build your plans on the assumption that asking will certainly produce a certificate. Check what the recipient requires first, then make an inquiry if you still need to. That order is the realistic one.

The similarly named distance and fare certificate is a different document

Search around for certificates connected with Toei Bus and you will run into another document that is easy to confuse with the first. It is the distance and fare certificate the Bureau describes. Going by the name alone you might take it for something to do with lateness, but what it certifies is a different matter entirely and has no bearing on delays.

According to that guidance, the certificate can be issued at Toei Bus depots and their branch offices, at Toei Bus pass sales offices, and at Toei Subway pass sales offices. The page adds a note asking for your understanding in advance, because issuing one can take a little time. It is not a document to count on collecting over the counter on the spot when you are in a hurry. As for the situations in which it is needed, the Bureau's page offers no particular explanation, so if someone has asked you for it by name, the sure approach is to take that request to a counter and ask there.

Part of what makes the mix-up so easy is that the address of the page carrying this guidance contains the word delay. People who see only the heading in a list of search results sometimes come away believing that Toei Bus has a delay certificate page of its own, yet the text of the page says nothing about a document certifying lateness. Since asking at a counter for a certificate and nothing more could send the conversation off in the wrong direction, say specifically what it is you need certified.

Keeping your own record that the bus ran late

If no official document exists, the practical form of preparation is to keep the evidence of the delay yourself. Two things help here: a record that you traveled, and a record of how the service was running at the time.

Take the record of travel first. The Bureau's frequently asked questions state that receipts for fares are not issued. If you paid with an IC card, however, a statement of use can be printed at stations, at bus depots, at pass sales offices and similar places. A printed statement carries the record of the payment, so it is at least a pointer to the fact that you used a bus that day. It shows a fare being paid, though, not a delay, so the explanation of the lateness has to be supplied alongside it.

Now the state of the service. The same frequently asked questions point to the Toei Bus service information site, tobus.jp, for expected journey times and service information. If you have a spare moment in the middle of a delay, saving the screen that shows the running state of your route gives you material for explaining the situation afterwards. The Busdoko top page also shows the positions of buses on the road and the expected arrivals for each noriba on a map.

None of these records is an official certificate. Compared with saying nothing more than "the bus was late because of traffic", though, an explanation backed by a route number and times is far easier for the other person to accept.

Common misunderstandings, and preparing for a day when a delay would hurt

To close, it is worth sorting out the misunderstandings that spread most readily around this subject. One is the claim that a Toei Bus delay certificate can be downloaded as a document from the official site. As of September 2026, no page on the Bureau's site can be found that distributes a document certifying a bus delay. Another is the claim that quotes a specific figure for the number of minutes of lateness at which one is issued. For buses, no such uniform standard is published. A number always looks authoritative, but if you plan around a threshold with no source behind it, you are the one left stranded when it turns out to be wrong.

The reading that a visit to a depot will certainly get you a document deserves caution too. There are places to make an inquiry, but no official guidance promises that a document will be handed over. It is also worth remembering that the rail certificates are issued against a line and a time band, and that the Bureau itself states they do not certify that the passenger traveled on that train. The word certificate suggests more evidential weight about an individual journey than these documents actually carry.

Seen in that light, the most reliable measure turns out to be the plainest one: catch a bus early enough that a delay still leaves you in time. On a day with a fixed commitment, treat the previous departure as your target, and check where the buses are with the approach information before you set off for the stop. Those two habits alone will cut down the occasions on which you find yourself looking for a certificate. How the position of a bus is worked out is explained in how bus location systems work, and reading departure times is covered in how to read a bus timetable. For the days when a delay cannot be avoided, get into the habit of noting down the route you boarded and the times.
