一、はじめてのスーツケース選びはなぜ難しい？

The reason why beginners have trouble choosing a suitcase is actually very simple.
Broadly speaking, there are only two reasons: "too much information" and " I can't imagine how much luggage I have."

■ 1.情報が多すぎて、違いがわからなくなる

  • Size (L, M, S)
  • Capacity (35L, 45L…)
  • Material (polycarbonate, ABS)
  • Opening and closing method (zipper/frame)
  • Caster type (2 wheels, 4 wheels, 8 wheels)

As a result, beginners will suddenly have too many factors to consider.
It's easy to get confused because it's unclear what criteria to use for comparison .

■ 2. 航空会社の規定がそれぞれ違う

Carry-on baggage size and weight limits vary by airline, and it's common to make the mistake of thinking you've bought something that's okay only to end up paying extra fees at the airport. Not knowing the subtle differences in regulations is especially likely to lead to regrets.

■ 3. 自分の旅行スタイルに合ったものがわからない

  • "Is one night and two days enough?"
  • "Is it a large trip for 3 nights and 4 days?"
  • "For business trips? Or for family vacations?"

The required size and features vary depending on the frequency and purpose of travel,

Even after reading online reviews, it's difficult to decide which one is best for me.

二、初心者はまず「3つだけ」見ればOK：迷わない基本の判断軸

Choosing a suitcase is actually very simple.
Beginners in particular will have almost no problems if they focus on the "three basics" rather than the detailed specifications.

Here we will introduce these three points as simply as possible.

■ 1.旅行日数でサイズを決める（最も迷わない方法）

First, just think of the number of nights x season as a guideline.
Before looking at the detailed capacity and numbers, please refer to the table below.

旅行日数 目安容量 コメント
1〜2泊 30〜40L 身軽に動きたい人向け
2〜4泊 40〜55L 初心者に最も使いやすい万能サイズ
4〜7泊 60〜80L 海外や長めの旅に便利
1週間以上 80〜100L お土産が増える旅なら安心

If you are a beginner and are unsure, it is best to choose a slightly smaller size rather than a slightly larger one, as it will be easier to handle.
Something that is light and easy to carry will make your first trip much easier.

■ 2.移動スタイルで素材と構造を選ぶ

Even for the same journey, the "required performance" will vary greatly depending on the means of transportation.

・People who travel by train or bus a lot
　→ Lightness and caster stability are paramount. Ease of movement is essential on narrow platforms and stairs.

・People who travel by car a lot
→ It's OK if it's a little heavy. Since there is storage space available for those who prioritize durability , a sturdy frame type is also an option.

・Frequently travel by plane (especially LCC)
　→ Prioritize size regulations. LCCs have strict size checks, so it's safer to choose a model that complies with the regulations.

Depending on your travel style, you may need something lighter or more durable .

Deciding this first will make it easier to choose.

■ 3.軽さとキャスターの質を優先すべき理由

This is something that many beginners tend to overlook.
However, when you actually use it, it is no exaggeration to say that these two things are the only things that directly contribute to reducing fatigue .

・"Lightness" determines the comfort of your trip
When traveling long distances, including stairs and stations, the difference in weight has a direct impact.
Beginners are more susceptible to this effect, so if you're unsure, it's best to choose the lightest model possible .

・The quality of the casters is the secret to zero stress
If the caster does not run smoothly,
- It moves diagonally - It stops - It's noisy - Your hands get tired, etc. It's difficult to use.

For beginners, the silent caster x smooth 8-wheel model is a safe choice.

三、これを選べば間違いない！初心者向けの定番スペック

"There are so many types of suitcases, which one should I choose?"
There is something like a correct template that responds to the voices of such beginners.

You don't need to compare in detail; just choose the following specifications and you'll be almost guaranteed not to go wrong.

■ 1.容量：40〜50L（2〜4泊用）

For beginners, 40-50L is the easiest size to handle.

  • Not too big, not too small
  • Suitable for domestic travel as well as short overseas trips
  • Even if you have little luggage, it won't feel empty.
  • There's also a reasonable amount of souvenirs to take home.

If you're unsure, the golden balance is around 45L .

■ 2.素材：軽くて丈夫な 「ポリカーボネート系」 が間違いない

The best materials for beginners are:

  • Full polycarbonate (PC) : Lightweight and impact resistant
  • PC + ABS hybrid : Lighter than PC and more affordable

These materials are easy to handle and will reduce stress even on your first trip.

■ 3.開閉方式：迷ったらファスナータイプ

The zipper type is easiest for beginners to use.

  • Very light
  • Easy to open and close on the go
  • Cheaper than frame type
  • Flexible in packing

There are many lightweight models available, making them ideal for beginners who prioritize ease of handling.

■ 4.キャスター：静音 × ダブルキャスター（8輪）

The comfort of your journey depends on the casters.
For beginners, the "Quiet x 8 wheels (double casters)" model is best.

  • Stable and straight forward
  • Easy to maneuver
  • Easy to roll even on uneven floors
  • Less fatigue and stress

The quality of the casters is especially important for beginners who will be navigating stations, airports, sidewalks, etc.

■ 5.ロック：TSAロックがあれば十分

For beginners, it's fine to just check whether the bag has a TSA lock rather than worrying about complicated security features.

  • It won't break even if it's opened during a trip to the US.
  • International standards for peace of mind
  • No problem with zipper type

Rather than special security features, prioritize the minimum level of security you need for your trip .
