When choosing a suitcase, an essential item for travel or business trips, many people are unsure which to choose, given the wide variety of types, functions, and sizes available. Questions like, "Is lighter better?", "Do I need one that's carry-on size?", and "Do I need quiet casters and brakes for train travel?" are common.

This article provides a clear explanation of how to choose a suitcase based on its intended use and specific requirements. We've selected recommended suitcases from the brand lineup available at "ISETAN SUITCASE" on the first basement floor of the Isetan Shinjuku store, tailored to each type of suitcase.

First, check your type using the type-based guide, and then find the perfect model for you from our list of recommended models.

First, let's look at four key points to consider when choosing a suitcase.

There are so many types of suitcases that it's easy to get confused and wonder, "Which one should I choose?"
In such cases, first organizing the following four points will make it easier to find a suitcase that suits you.

1. Destination (Domestic/International)

The points you prioritize differ between domestic and international travel.

• Overseas travel : Features such as durability, security, and maneuverability are necessary for checked baggage and long-distance travel.
• Domestic travel : Lightweight, carry-on size, ease of handling, etc., for ease of travel.

2. Number of nights (capacity)

First, determine the approximate capacity based on the length of your trip.


*For detailed capacity and size information, please see the next page.

► "Check the guidelines for carry-on baggage size and capacity."

3. Usage Scenarios

The necessary functions vary depending on how you use it, such as for travel or business trips.

for example,

• For frequent business travelers: Carry-on baggage, front pocket

Learn more about the features you're interested in.

Suitcases have numerous features and specifications designed to make travel more comfortable and ensure the safe transport of your belongings. Here, we'll detail the features you should check, depending on your travel style and what's most important to you.

① Choose between frame type and zipper type

---

Suitcases can be broadly divided into two types: "frame type" and "zipper type." Each type has different characteristics, so choose one that suits your travel style.

■ Frame type

Its frame-closure structure makes it highly resistant to impact and provides excellent security. It is recommended for those who travel abroad frequently, have a lot of checked luggage, or prioritize durability.

■ Zipper type

Its lightweight design, ease of opening and closing, and overall light weight are its main attractions. It's ideal for domestic travel, trips involving frequent movement, and for those who prioritize lightness.

② If you prioritize lightness

---

The lighter the suitcase, the less strain it puts to lift and carry up and down stairs. Another advantage is that it allows for more flexibility in meeting airline weight limits.
Some models utilize lightweight materials such as polycarbonate and clever design features and structures within the case to reduce weight while maintaining strength, so be sure to check them out.

③ If you want to travel comfortably by train or bullet train

---

In train stations, on platforms, and inside crowded trains, the maneuverability of your suitcase greatly affects your comfort.

"Silent casters" reduce noise during operation, allowing you to move around considerately even in the early morning, late at night, or within train stations. Additionally, "caster stoppers" prevent accidental rolling on trains or slopes, providing peace of mind.

Also check these points: double-wheel casters, etc.

④ If you want to load and unload your luggage smoothly

---

If you frequently need to access your PC, documents, and other small items while traveling for business or other reasons, pay attention to storage capacity.
The " front pocket " allows you to quickly access your laptop or documents, making it convenient for business trips and airport procedures. Furthermore, the " front opening " allows you to easily pack and unpack your belongings in a compact space.
Furthermore, some models with a USB port allow you to connect a mobile battery and charge your smartphone or other devices while on the go.

⑤ If you are going on an overseas trip

---

When traveling abroad, it's important to choose a device with features that also prioritize security.
A "TSA lock" is a recommended locking system for travelers to the United States (including Hawaii and Guam). You can check in your luggage with the lock engaged, and airport staff can unlock and inspect it using a special key.
Furthermore, since you'll often be traveling on cobblestone or unpaved roads overseas, and frequently need to leave your luggage, it's recommended to choose a bag with not only security features but also a shock-resistant body and highly durable materials.

Also check these points: frame type, durable materials, suspension, etc.

⑥ If you think you'll have more luggage

---

If you plan to buy souvenirs or have extra luggage during your trip, pay attention to the storage capacity of your bag.
With an " expandable (capacity expansion) function ," you can widen the gusset width as needed to increase storage capacity.
Furthermore, models with ample interior dividers and storage pockets make it easier to organize your belongings and prevent the contents from becoming disorganized while you're on the go.

Also check these points: interior divider structure, luggage securing straps, number of storage pockets, etc.

Check the guidelines for carry-on baggage size and capacity.

When choosing a suitcase, be sure to check not only its capacity but also whether it's the right size to carry onto an airplane.
A general guideline for capacity is "about 10L per night," but the required capacity will vary depending on the amount of clothing, the season, souvenirs, etc. If you tend to pack a lot, it's a good idea to choose a size with a little extra room.

If you are traveling by plane, be sure to check whether your bag is within the carry-on size limits or requires you to check it in as checked baggage.

■ General guidelines for carry-on baggage size

• - The sum of the three sides is within 115cm.
• ・Weight within 7-10kg

*Regulations may vary depending on the airline. It is recommended to check the rules of your airline in advance.

■ Estimated capacity based on the number of travel days

Number of travel days	Capacity guide	Recommended uses
1-3 nights	~30L	Business trips, domestic travel, carry-on luggage
2-4 nights	30-49L	Domestic travel/short distance overseas travel
4-6 nights	50-79L	Domestic travel/overseas travel
More than a week	80L and up	Long-term travel, study abroad, family travel

Tip: If you have a lot of luggage or plan to buy souvenirs, it's best to leave a little extra capacity for a more comfortable experience.
