A Guide to Luggage for Highway Bus Passengers: Can It Be Stored in the Trunk? What Are the Size Limits?

When riding a highway bus, you may wonder: Can I store large luggage in the trunk? Is there a limit on the number of items? Let us answer these questions and provide a comprehensive guide to luggage storage when traveling by highway bus.

１．About the Trunk Room of Highway Buses

Many people assume that all highway buses are equipped with trunk rooms. However, this is not always the case. Even if a trunk room is available, there are restrictions on the size of luggage that can be stored. Let’s explore this in detail.

１-１．Availability of Trunk Rooms

The availability of a trunk room varies depending on the bus company. If you have large luggage such as a suitcase, it’s essential to confirm this before booking.Most buses are equipped with trunk rooms. However, double-decker buses may not have a trunk room as the first floor is typically used for seating. That said, even if a bus lacks a trunk room, there may still be designated storage areas for luggage.Information about trunk room availability is often listed on the reservation website. If it’s unclear, contact the booking provider for clarification.

１-２．Luggage Size Limits

The size of luggage acceptable for storage in the trunk is often similar to the size allowed for carry-on luggage on airplanes.For domestic flights with fewer than 100 seats, the carry-on size limit is as follows: the sum of the height, width, and depth must be within 100 cm, and no single dimension can exceed 55 cm × 40 cm × 25 cm. One item per passenger is allowed.While many bus companies adhere to similar size limits, exceptions exist. When inquiring about trunk room availability, it’s also a good idea to confirm the size limits for stored luggage.Additionally, note that bus companies typically do not provide compensation for lost or damaged luggage. Store your items in the trunk at your own risk.

１-３．Prohibited Items for Trunk Storage

Does this mean anything within the size limits can be stored? The answer is no. Items stored in the trunk are expected to be travel essentials such as clothing.Even within size limits, the following items are prohibited:

• Hazardous materials (explosives, flammable items, knives)
• Folding bicycles
• Musical instruments
• Pets
• Golf bags
• Sports equipment
• Long, thin items (e.g., bamboo swords)

Fragile items are also generally not allowed, as bus companies do not provide compensation for damage. Oversized suitcases exceeding the size limit are also prohibited.

２．What Luggage Can Be Brought Inside the Bus?

Now that we’ve covered trunk storage, let’s look at what luggage can be brought inside the bus.Valuables should not be placed in the trunk but instead kept in a small bag that you bring into the bus.As a rule of thumb, luggage brought inside should fit within the overhead shelf or be manageable at your seat. Since shelf sizes vary by bus type, it may be helpful to confirm the dimensions beforehand.

３．Frequently Asked Questions

Here are some common questions received at a highway bus reservation center.

Q1: My luggage slightly exceeds the size limit. Can it still be stored?

A: If your luggage exceeds the size limit, it may be refused on-site. Ensure your luggage is within the size restrictions to avoid issues, as there’s a high chance you may not be allowed to board.

Q2: What happens if my luggage is refused on-site?

A: You can ship your luggage from a nearby convenience store, but buses depart on time and will not wait. Alternatively, you can cancel your ride, but cancellation fees will apply.

Q3: Can I place large luggage at my seat instead of in the trunk?

A: Large luggage is not allowed inside the bus as it can inconvenience other passengers. For example, placing items at your feet can prevent passengers in front of you from reclining their seats. Snowboards or musical instruments placed upright are also prohibited due to safety risks during sudden stops.

Q4: What should I do if my luggage exceeds the size limit?

A: Consider shipping your luggage to your destination in advance or exploring alternative transportation methods.

Q5: Will the bus company compensate for damaged luggage?

A: Bus companies do not provide compensation for damaged or lost luggage. If you’re concerned, consider purchasing insurance that includes luggage damage coverage.

Q6: Can I place my luggage on the overhead shelf?

A: Some buses lack overhead shelves. Even if shelves are available, they are often small (only large enough for coats). Additionally, items may fall during turns or sudden stops, so placing luggage on the shelf is not recommended.

Q7: Can I store two large items in the trunk room?

A: Most bus companies allow one piece of luggage per person. However, some buses permit two items. Confirm with the booking provider in advance.
