What you can bring on a Toei bus: suitcases, bikes and pets

The two limits that decide everything: 250cm in total, and one hand

The rules for bringing luggage onto a Toei bus are easiest to remember if you start with the numbers. As of September 2026, the Tokyo Metropolitan Bureau of Transportation allows items to be carried into the cabin as hand luggage when their height, width and depth add up to 250cm or less, their length is 2m or less, and they weigh 30kg or less.

Two conditions attached to them are easy to miss, though. The first is that the limits apply not to each individual item but to the combined size of everything you bring aboard. The second is that you must be able to hold all of your hand luggage in one hand. The official page even explains why: for safety reasons, one hand has to stay free so that you can hold on to a strap or a handrail.

One further condition sits above all of these. Even for luggage that fits the stated sizes, the Bureau notes that passengers may be asked to refrain from bringing items aboard when the bus is crowded, and that items judged to present a safety problem may be restricted. The numbers, in other words, are the threshold for getting on; the final test is the state of the cabin and the safety of everyone in it. The sections below work through how that plays out case by case.

Suitcases and wheeled cases: where you stand matters more than the size

A 250cm total is a generous allowance for anyone traveling with a single suitcase, so dimensions alone are rarely the issue. What actually causes trouble is where the case ends up once you are aboard.

Among the things that may not be brought onto a Toei bus, the Bureau lists anything liable to block the aisle, the doors or the emergency exit. Suitcases are not banned as such; it is simply that a badly placed one runs into that condition. If you have a seat, stand the case upright at your feet and steady it with a knee or a hand. If you are standing, keep it against the side wall of the vehicle or tucked beside a seat so that the aisle and the space in front of the doors stay clear. Castors roll away on their own on a flat floor, so always keep a hand on the case while the bus is moving.

The official guide to using the buses adds one more warning: boarding with luggage in both hands is described as extremely dangerous. A bus slows suddenly for traffic lights and congestion, and a posture that leaves you unable to grab a strap or handrail leads directly to a fall. When you are carrying a paper bag or a rucksack as well as a suitcase, rearrange things before you board, for example by putting the rucksack back on your shoulders, so that one hand is free.

On routes inside Tokyo's 23 wards you board through the front door and pay as you get on, so at the door you have to gather your bags into one hand and settle the fare in the same short moment. An IC card needs only a single tap, which makes it especially well suited to a day with big luggage. The details of each payment method are set out in our guide to Toei bus fares and how to pay.

Bicycles and kick scooters: bag them, or use the cycle bus

Bicycles are allowed, but only on conditions. The official page states that bicycles, balance bikes, kick scooters and other items with protruding parts or wheels may be brought aboard only when their moving parts have been secured and they are stowed in a purpose-made bag. In practice the dividing line is whether you can get the whole machine into a bag with the wheels and handlebars held still, as you can with a folding bicycle or a proper bike bag. Wheeling it on unbagged, or covering only the wheels, does not qualify. Once bagged, it still has to satisfy the general limits for hand luggage. Kick scooters and balance bikes are treated the same way.

If you want to move an ordinary bicycle that will not go into a bag, there is a route where a Toei bus can carry it on a rack at the front. As of September 2026, the Tokyo Metropolitan Bureau of Transportation is running a trial service on the 梅01 (Ume 01) route, which operates on Saturdays, Sundays and public holidays, using buses fitted with a front-mounted cycle rack that holds two bicycles. There is no charge for carrying a bicycle. Only single-rider bicycles are eligible, the frame alone and up to two of them, and they cannot be brought into the cabin. The stops where bicycles may be loaded and unloaded are fixed, and when a rack-equipped bus runs on a route other than 梅01 the rack cannot be used.

Eligible bicycles also have to meet standards for wheel size and weight, and some models are given as examples that fall outside them. Loading and unloading is done at the passenger's own responsibility, so before you set out it is worth checking the standards, the designated stops and the timetable on the Bureau's own page, how to use the cycle bus.

Instruments and club gear: no special rule, so the general limits decide

Anyone carrying an instrument wants to know whether a big case will be turned away. As of September 2026, the Toei bus guidance contains no rule that names musical instruments. The test is therefore the same one that applies to any hand luggage: does the case come within 250cm for its three dimensions combined, 2m in length and 30kg in weight, and can you hold it in one hand together with whatever else you are carrying?

Judged that way, cases you can carry in one hand, for a guitar, a bass, a trumpet or a flute, have room to spare on both counts. A cello, a double bass or a large percussion instrument is another matter: long or wide, and impossible to move without both arms, such a case may fall short on the dimensions or on the way it has to be held. Layered on top of that is the principle that passengers may be asked to refrain even with luggage inside the limits when the bus is crowded. The accurate answer, then, is neither a guaranteed yes nor a guaranteed no.

Sports and club equipment can be thought through in the same way. A racket bag, a bag for kendo shinai, or a holdall packed with a helmet and boots all count as hand luggage as long as the whole load stays within what one hand can hold. The thing to watch is a large bag on castors, because anything with wheels is allowed only when its moving parts are secured and it is stowed in a purpose-made bag.

Pets: a fully enclosed case, and only detachable, foldable carts

Whether you can travel with a dog or a cat is the part of the Toei bus rules with the finest conditions attached. The starting point is the official statement that, guide dogs and service dogs aside, animals are as a rule not accepted aboard. Two exceptions are then set out for small pet animals.

• In a fully enclosed case: when the animal travels inside a case, a carrying bag included, that leaves no part of it such as the face or the paws exposed.
• A detachable pet cart, folded down: when the case and the cart can be separated, and the cart part has been folded up in advance.

Conversely, a pet cart that does not fold, and a pet sling, will be refused. The reasons given are the space in the cabin, safety, and the risk of inconveniencing other passengers, and consideration for people who are uneasy around animals or who have allergies is stated explicitly as well. A carrier or a mesh sling that leaves the head or the legs sticking out is therefore outside the exceptions, however small the dog.

Even when your arrangement does fit one of the exceptions, the sizes and the cautions covered in the earlier sections still apply. The case has to come within 250cm for its three dimensions combined, 2m in length and 30kg in weight, and you must be able to hold it in one hand along with your other bags. What decides matters at the door is whether the whole thing fits in a single carrier you can hold in one hand. If you are using a cart, note as well that the folded cart and the case are measured together.

The exceptions named in the official text are guide dogs and service dogs. For the detailed treatment of traveling with a guide dog or a service dog, check with the Tokyo Metropolitan Bureau of Transportation in advance.

Luggage that can be refused, and what happens at the door

So far this has been about the conditions for getting luggage aboard, but the official page also lists what may not be brought on. It names corpses, animals (apart from the exceptions in the previous section), dangerous goods, harmful substances, anything liable to block the aisle, the doors or the emergency exit, and anything liable to soil or damage the vehicle, and, as the closing "and the like" signals, the list is not exhaustive. Rather than working item by item, it is more practical to check your own load against three questions: is it dangerous, could it obstruct other people's movement or their escape, and could it dirty the cabin or someone else's clothes?

Seen that way, the awkward cases are things like a jerry can of kerosene or petrol, a large aerosol canister, gear still soaking wet with rain or mud, and strong-smelling fresh food. None of these is banned by name, but any of them could be judged to fall under dangerous goods or under items liable to soil the vehicle. Putting them in a waterproof bag, or double-wrapping them, removes the doubt.

Luggage that meets the stated rules may still not be let through. The official page states plainly that even for hand luggage within the stated sizes, passengers may be asked to refrain from bringing it aboard when the bus is crowded, and that items judged to present a safety problem may be restricted. A crew member is weighing up the safety of the whole cabin in the few seconds available, so if you are questioned at the door, switching to another plan on the spot, rather than arguing it out, is the quicker way through.

• Fold down whatever folds, and bag whatever will go into a bag.
• Rearrange your bags into one load so that one hand is free.
• Wait for the next bus, or shift to a different time of day.

How to prepare for the crowding itself is covered in our guide to riding out a packed bus, which is worth reading alongside this article on a day when you have a lot to carry.

On a big-luggage day, start by picking a quieter bus

Looking back over the conditions, there are not many situations in which the size limits are what stops you. The real dividing lines come down to two things: whether you can keep one hand free, and how full the bus happens to be. On a day with a suitcase or an instrument, choosing your departure with the same care you give to packing keeps you away from the situations where luggage is refused in the first place.

The Busdoko home page shows, on a map, where the buses are running and the expected arrivals at each boarding point. Knowing how many minutes are left until the next bus makes it much easier to let a crowded one go rather than forcing your way aboard. If it is the flow of boarding and alighting itself that worries you, run through the steps in our guide to how to ride a Toei bus and you will be able to shift your bags and pay at the front door without hurrying.

For an item whose size or shape you cannot settle from the official guidance, the sure course is to ask the Tokyo Metropolitan Bureau of Transportation before you set out. Raising it for the first time at the boarding door tends to leave the people behind you waiting and still produce no answer.
