Yes, you can bring luggage under 240 cm on Willer Express buses, but with a major catch: 240 cm is the combined total dimension limit for two bags, not a single piece. Under the official Willer Express baggage policy, the maximum total dimensions (length + width + height) for any single piece of trunk luggage is 155 cm. If a single suitcase exceeds 155 cm, it will be rejected at boarding, and you cannot pay extra fees to bypass this limit.
When traveling by highway coach in Japan, knowing the exact rules for carry-on and hold bags is the key to a stress-free trip. In this guide, we break down the size, weight, and item restrictions for Willer Express and its partner operators so you do not get left behind at the bus terminal.
Willer Express Luggage Allowance: At a Glance
Willer Express enforces strict rules to ensure passenger safety and comfort. Unlike airlines, there are no options to pay for excess baggage. The table below summarizes the allowance limits for standard routes operated directly by Willer Express or Star Express.
| Baggage Category | Quantity Limit | Maximum Sizing Limits | Maximum Weight | Extra Fees |
|---|---|---|---|---|
| Carry-on Luggage (Cabin) | 1 piece per passenger | Total linear dimensions ≤ 100 cm (length ≤ 1 m, volume < 0.027 m³) | 10 kg (22 lbs) | Free (No excess options) |
| Trunk Luggage (Hold) | Up to 2 pieces per passenger | Max 155 cm (61 in) per piece; combined total for 2 pieces ≤ 240 cm (94 in) | No explicit limit (must be liftable) | Free (No excess options) |
What are the size and weight limits for Willer Express trunk luggage?
Each passenger can store up to two pieces of luggage in the bus trunk. For one piece, the sum of height, width, and depth must not exceed 155 cm. If you store two pieces, their combined dimensions must not exceed 240 cm, and neither bag can be larger than 155 cm. These rules prevent overloading the bus and guarantee space for all travelers.
Please note that specific airport shuttle routes operated by Willer Express (such as the Narita Shuttle to Ikebukuro or Osaki, and the Mishima Haneda Shuttle) permit only one piece of trunk luggage per passenger due to limited storage capacity.

What are the cabin carry-on rules for Willer Express?
You can bring one carry-on bag into the passenger cabin for free. The bag must weigh less than 10 kg (22 lbs) and fit within a total linear size of 1 meter (length + width + height). Additionally, the volume of the carry-on item must be under 0.027 cubic meters (approximately 27 liters) to ensure it fits in the overhead rack or under your seat.
Willer Express recommends using soft-sided bags or backpacks for the cabin. Hard-shell suitcases are discouraged because they do not flex to fit in the overhead racks and can block your legroom if placed at your feet, creating a safety hazard in an emergency.
Can you bring sports equipment and bicycles on Willer Express?
Skis, snowboards, and golf bags are permitted in the bus trunk on single-decker buses as an exception to the 155 cm rule. However, you are limited to only one such item per passenger, and it must be stored in a protective cover or bag. These oversized sports items are strictly prohibited on double-decker buses because those vehicles lack holds.
Bicycles (including folding bikes and disassembled bikes stored in transit bags) and surfboards are strictly prohibited on all Willer Express routes. If you plan to travel with a bicycle in Japan, you will need to use a train service (using a Rinko bag) or ship your bike ahead of time using a local delivery service like Yamato Transport.
Are musical instruments and pets allowed on Willer Express?
Small musical instruments like guitars and basses are accepted in the bus trunk, provided they are stored in a sturdy hard case and fit within the 155 cm dimension limit. Large instruments, such as cellos, double basses, or drum kits, are not accepted. Valuables and fragile instruments should be carried in the cabin if they meet carry-on size limits, but you assume all risk for damage.
Pets are strictly prohibited on all Willer Express buses. You cannot bring dogs, cats, birds, or other animals in carriers, either in the cabin or the trunk. Service dogs (such as guide dogs) are permitted in accordance with Japanese law, but you should notify Willer Express in advance when making your booking.

Do double-decker buses have different luggage rules?
Double-decker buses operated by Willer Express (including Executive, Value, Sleeper, and select buses equipped with toilets) have extremely limited or no trunk space. Because of these structural limits, large suitcases and oversized sports gear cannot be stored in the trunk of a double-decker bus. If you book a double-decker route, you must pack light and limit your luggage to carry-on items that fit within the cabin compartments.
What are the luggage rules for partner bus operators?
If you book a bus ticket on the Willer Travel website that is operated by a partner company (such as JAM JAM Express, Hankyu Bus, or Kintetsu Bus), you must follow that specific operator’s luggage rules. These partner rules are often much stricter than Willer’s standard policy.
For example, buses operated by JAM JAM Express restrict passengers to a single piece of trunk luggage. This bag must not exceed 120 cm in total dimensions and must weigh less than 10 kg. Exceeding this limit will result in being denied boarding at the platform. Furthermore, partner operators like JAM JAM Express, Hankyu Bus, and Kintetsu Bus do not accept any musical instruments in the trunk.
Always verify the “Operating Company” listed on your booking confirmation and check their specific luggage policies before heading to the station.

- Hazardous Materials: Explosives, fireworks, flammable liquids (gasoline, kerosene), compressed gases, and toxic or corrosive chemicals.
- Valuables and Fragile Items: Cash, passports, high-value jewelry, electronics (laptops, tablets), and antiques must not be stored in the trunk. The trunk is subject to temperature changes and physical vibrations; keep these in your carry-on bag.
