一、ビジネス出張用スーツケースと旅行用の違いとは？

When choosing a business suitcase, it is important to consider the following criteria:

By choosing the appropriate model depending on the frequency and duration of your business trips, your means of transportation, and the contents of your luggage,

This makes for an efficient and comfortable trip.

Below we will explain in detail the size, material, caster performance, and security.
項目 観光旅行 ビジネス出張
主な荷物 衣類・お土産 PC・書類・スーツ
重視する機能 容量・デザイン 機能性・使いやすさ
荷物の出し入れ 宿泊先で一度だけ 移動中に頻繁に出し入れ
移動スタイル 観光地を回る 駅・空港・オフィス間の移動
求められる機能 拡張機能 フロントオープン・ストッパー

The size of your suitcase will depend greatly on the length of your trip and your mode of transportation.

Choosing the right size will help you avoid over- or under-packing and reduce the stress of traveling.

・Carry-on compatible :

For business people who fly frequently, a carry-on business suitcase is essential.

The standards for major Japanese airlines (ANA and JAL, with more than 100 seats) are that the total of the three dimensions must be within 115cm (e.g. 55 x 40 x 25cm) and the weight must be within 10kg .

For low-cost carriers (e.g. Peach), the standard size is 50 x 40 x 25 cm and 7 kg or less .

・4 to 7 nights (approx. 60L or more):

It is suitable for long-term stays, or when you have a lot of luggage such as thick clothes for winter or exhibition materials.

二、ビジネス出張用スーツケースの選び方｜4つのポイント

When choosing a suitcase for a business trip,

it's important to consider not just its capacity, but also whether it can easily store your work tools and if it's convenient to use while traveling.

Here are four key points for choosing a suitcase suitable for business trips.

出張日数に合ったサイズ・容量

The most popular suitcases for business use these days are:

The "front-open" function allows you to open and close the unit while it is standing upright, without having to lay it on its side.

- Laptops and documents can be easily taken in and out

You can quickly access small items such as your laptop, tablet, work documents, or mobile battery without opening the main compartment, making it easy to handle sudden tasks while waiting or on the move.

- Easy to organize luggage even in public places

It's hard to open your suitcase fully in public places like airport lobbies or train platforms. By opening and closing only the front pocket, you can keep your private belongings hidden and keep only the essentials organized.

出張期間 目安容量 サイズ
1〜2泊 30〜40L Sサイズ
3〜5泊 40〜70L Mサイズ
1週間以上 70L以上 Lサイズ

For short business trips, an S-sized carry-on is suitable, while an M-L size is appropriate for longer trips.

※For more detailed information on choosing the right capacity for 2-night and 5-night trips, please refer to our separate article: "How to Choose the Best Suitcase for Business Trips: Capacity Guidelines and Recommended Models for 2-Night and 5-Night Stays."

PC・書類を収納しやすい構造

For business trips, you need to safely carry not only clothes but also laptops and documents.

Therefore, we recommend models with the following storage features:

  • Front-open function: Allows you to retrieve your PC or documents without opening the main compartment of the suitcase while on the go.
  • Dedicated PC pocket: Protects your laptop from impact.
  • Divided storage: Makes it easy to organize chargers and cables.

Especially on bullet trains and at airports, there are often situations where you need to quickly check documents or take out your PC, so the usability of the storage structure is crucial.

長時間移動でも疲れにくい走行性能

On business trips, you may have to travel long distances with a suitcase between stations, airports, and hotels.

Therefore, the running performance that reduces the burden during travel is also an important point.

Features to check:

  • Lightweight design: Reduces the burden of lifting and carrying up stairs
  • Silent casters: Allows for comfortable movement even early morning or late at night
  • Stopper function: Can secure the case on trains or sloped surfaces

These are not individual features, but rather it is important to choose them from the perspective of "making travel comfortable during business trips."

出張頻度に合わせた耐久性・デザイン

The more frequently you travel for business, the more important the durability of your suitcase becomes.

If you use it often, choosing a shock-resistant material will allow you to use it comfortably for a long time.

Recommended materials:

  • Polycarbonate (PC): Good balance of lightness and impact resistance
  • ABS+PC: Excellent durability and cost performance

Also, if you will be using your suitcase with clients or in an office setting, choosing a subdued color such as black, navy, or gray will allow it to blend naturally into business situations.

三、出張スタイル別｜あなたに最適なスーツケースは？

New Trip offers multiple sizes so you can choose the one that best suits your business trip duration and purpose.

- "S size" suitable for short business trips of 1-2 nights

The lineup is centered around carry-on sizes. They are ideal for short domestic business trips where you want to avoid the hassle of collecting your luggage after arriving, or for those who want to travel light and easily. Choosing a front-opening model will make travel even more efficient.

国内日帰り〜2泊出張が多い方

When traveling on business, many people travel by public transportation,

The following small features will affect the actual usability:

・Caster stopper

This prevents your suitcase from rolling around while traveling on a train or bus. You no longer need to constantly hold it down with your hands or feet, allowing you to spend your time waiting in the car more relaxed.

・Capacity expansion (expandable)

When you bring back documents distributed on a business trip or when your luggage increases with souvenirs, you can simply open the zipper to expand the gusset and increase the storage capacity. One size can be used flexibly, making it convenient for business trips where the amount of luggage you carry is likely to change.

・Drink holder ・Side hook

The drink holder that can hold a drink while you're on the move and the side hook that can hang a small carrier bag are useful for keeping both hands free, so you can answer the phone, use your smartphone, check your ticket, and more.

四、出張時に役立つ便利な使い方

- M and L sizes are suitable for long stays or when you have a lot of luggage.

It's suitable for trips where you'll need to bring lots of clothes and gear, such as for stays of several days or overseas business trips. Made from durable materials and with a secure locking mechanism, it offers peace of mind when traveling long distances or checking in luggage.

1. Store your PC in the front pocket.

If you need to use your PC while on the go,

it's convenient to store it in the front-opening section or a dedicated pocket.

Even if you suddenly need to take out your PC at airport security or on a bullet train,

you can do so smoothly without having to fully open your suitcase.

2. Store documents in a place where they won't get creased.

Documents such as contracts and presentation materials can get bent or creased if placed between soft items like clothing.

Utilize the internal dividers or flat storage compartments of your suitcase to keep them in their original shape.

3. Place heavy items on the caster side

For stable suitcase movement, the center of gravity of your luggage is also important.

By storing heavy items such as PCs, documents, and shoes closer to the caster side, you can reduce wobbling when pulling the suitcase and minimize fatigue during long trips.

By being mindful of "where to store items" in this way, you can make better use of your suitcase's functions for business trips.

よくある質問（FAQ）

Q1. ビジネス出張用スーツケースと旅行用の違いは？

A1：最大の違いは「荷物の出し入れ頻度」です。出張では移動中に頻繁にPCや書類を取り出すため、フロントオープン機能やストッパー機能が重要になります。また、スーツをしわなく収納する必要もあります。

Q2. 出張用スーツケースで最も重要な機能は？

A2：フロントオープン機能です。駅や空港、ホテルで全体を開けずにPCや書類をサッと取り出せるため、時間の節約になります。次いで、ストッパー機能も電車移動が多い出張では重宝します。

Q3. 国内出張にTSAロックは必要ですか？

A3：国内出張では必須ではありませんが、海外出張もある方はTSAロック付きを選ぶと安心です。国内でもセキュリティ面で安心感があります。

Q4. 出張用スーツケースは観光旅行にも使えますか？

Q5. スーツケースの色はビジネスシーンでは何色がいい？

A5：ブラック・ネイビー・グレーなど、落ち着いた色が無難です。取引先の前でも違和感のない色を選びましょう。明るい色やカジュアルな柄は、ビジネスシーンでは避けた方が無難です。

Q6. 軽量モデルと耐久性モデル、どちらを選ぶべき？

A6：週1回以上出張する方は耐久性重視、月1〜2回程度なら軽量性重視がおすすめです。頻繁に使う場合は、多少重くても耐久性の高い素材（ポリカーボネート）を選びましょう。
