Baggage with an overall dimension of less than 160 cm (the same size as baggage that may be transported for free in airline holds) can be placed on the Shinkansen's overhead baggage rack. We recommend that you reserve a seat with an oversized luggage area if you want to utilise that space. The same rule applies to many other types of trains in Japan.
In addition, most stations have porters who will help you with your bags or offer to carry them for you. These men work for the railway company and are called "kyudan-kuroutou" (櫃ダン回り).
You can also hire a private car at most major airports to take your luggage to your next destination. This service is expensive but it is faster than taking the train and saves you from having to find a place to leave your bag while you're away from it.
Finally, some hotels will hold your bag for you if you give them 24 hours' notice. They will charge you a fee for this service but it will allow you to go about your business without worrying about your valuables.
Traveling with Luggage on the Shinkansen The following rules apply while boarding the Shinkansen: You are permitted to carry up to two pieces of luggage on board for free. Without prior reservation, luggage no more than 160 cm (sum of height, length, and breadth) can be transported aboard. Exceeding this limit will incur a charge.
However, if you have a ticket with a reservation, your bag will be transported directly to your room or seat. If there is no space available in these locations, the operator will put you in contact with another passenger who can help accommodate your bag.
In addition, if you have a reservation but do not use it all, you can keep your bag with you until the end of your trip. In this case, too, it will be transported directly to your room or seat, and we recommend that you make sure you have chosen a quiet spot away from the train's path.
Finally, if you have a reserved seat but need to leave your bag behind, there will be a baggage handler at the station who will take care of it for you.
These are the general rules for traveling with luggage on the Shinkansen, but cases may arise that were not mentioned here. In such instances, the operator's agents at stations will know how to deal with them.
The general guideline is that carry-on luggage cannot be longer than 22 inches, width than 14 inches, or deeper than 9 inches. In many circumstances, you'll also have to deal with weight restrictions. The standard limit for a personal item is 50 pounds, while the maximum allowed on an airline is 90 pounds. Some carriers have additional requirements; for example, American Airlines requires that all checked bags weigh less than 80 pounds.
Carry-on bags can include backpacks, fanny packs, handbags, camera bags, and other containers. If you want to bring a large bag on your flight, consider checking it into your car at the airport or using a service like AB Bag for a bit of extra space when you travel.
Checked bags are held by the carrier and included in any fare type. Most airlines allow one checked bag and one carry-on per passenger. However, some carriers have increased their bag limits over time as demand has changed. For example, Southwest allows two bags of up to 40 pounds each.
If you decide to check your bag, there are several things to know before you go to avoid any delays in processing your claim. First, make sure that your bag will fit in the trunk of a car. Many carriers require that your entire bag be able to fit inside a trunk measuring approximately the same size as your vehicle's trunk.
