FAQ (Frequently Asked Questions)

一、自分にぴったりのスーツケースを見つけよう

When planning a trip, one of the first important items to consider is a suitcase . Knowing what type of suitcase is suitable for your travel style and duration is the first step to making your trip smoother and more comfortable. So, what points should you pay attention to when choosing one?

1. 「泊数」だけで決めて大丈夫？知っておきたいサイズ選びのコツ

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

For example, the amount of storage required for a short trip of one or two nights will be different from that required for a long trip of a week or more.

・Short trips (1-2 nights) :
For short trips, a 20-22 inch suitcase is ideal.

This size suitcase can be carried on board an airplane and is convenient for travel.

You can efficiently pack only the minimum amount of belongings, such as clothes and cosmetics.

・Long-term trips (7 days or more) :
For longer trips, we recommend a suitcase that is 28 inches or larger .

This size allows you to store your clothes and essentials with ease.

You can take everything you need with you before you leave home.

A larger suitcase is especially convenient for long-term stays or overseas travel.

It is important to choose the appropriate size based on the purpose of your trip, the season, and the amount of luggage you will be carrying.

Choosing the right size for your travel style will help you avoid unnecessary stress when traveling.

2. 「本体の軽さ」をチェックして、もっと自由にパッキング！

Suitcases can be broadly divided into two types: hard and soft .

Which one you should choose depends on your trip and your needs.

・Hard suitcase :
The hard type is made of a hard material on the outside and is suitable for protecting fragile items .

For example, hard types are advantageous when transporting items such as glassware or precision instruments.

It is also highly waterproof, so it can handle sudden rain .

However, due to its lack of flexibility, you may find that it doesn't have enough space if you want to carry even a little extra luggage.

・Soft suitcase :
The soft type is flexible and stretchy, and can be adjusted to fit the amount of luggage, making packing easy .

If the exterior is made of cloth, it is also lightweight and easy to carry.

However, since it does not have a hard outer shell, it is vulnerable to impacts .

Also, from a security standpoint, outer pockets can be a common target.

Choose which type is best for you based on the nature of your trip and the contents of your luggage.

Q2. LCCの「7kg制限」をクリアするコツは？
