FAQ (Frequently Asked Questions)

一、3泊4日のスーツケース選びは3ステップで考える

A four-day, three-night trip is the most popular length of stay, from domestic weekend trips to nearby Asian destinations like Korea and Taiwan. However, when it comes to packing, many people are left wondering, "Will I be able to get away with just carrying it on board?" or "Will I have to check it in?"

First, start by finding out the approximate capacity (L) that suits your travel style.

STEP1: サイズを決める

Women tend to carry more luggage than men, not only with clothes but also with hair irons and cosmetics.

First, find out which style suits you best.

・Carry-on luggage (up to approximately 40L)

・Advantages: After arrival, you don't have to wait at the baggage claim area and can start traveling immediately. There is no need to worry about lost baggage.

Disadvantages: There is little room to buy more souvenirs on the way back. If you put winter clothes or bulky shoes in the bag, it will easily become full.

・Checked baggage (medium size, approximately 60L)

・Advantages: You can bring bottles of lotion and hair care products with you. You can also pack plenty of souvenirs on the way home without worrying.

Disadvantages: You will have to wait at the airport. It's a little heavy when going up stairs or on the train.

STEP2: 自分に必要な機能を決める

The ideal capacity for a 3-night, 4-day trip is 40L to 60L , but the best choice is based on the following criteria.

・Those who should choose "40L (S size)":

- For summer travel or minimalist people who like to carry less luggage.

- Those who plan to mail souvenirs at the airport or bring them home in a secondary bag.

・People who are recommended to choose "60L (M size)":

- Traveling in winter (when sweaters and coats are bulky).

- People who enjoy shopping while traveling and want to pack all their souvenirs in their suitcase.

If you want to fulfill your wish of "I want a compact bag on the way there and a large capacity bag on the way back," a wise choice would be to choose a model with an "expandable capacity" function that allows you to increase the capacity with just one zipper.

STEP3: 自分に合うモデルを選ぶ

Once you've decided on the necessary size and features, all that's left is to choose a model that suits your travel style. This article will clearly explain the differences in each feature and introduce recommended models.

二、 女性が3泊4日用スーツケースを選ぶときの5つのポイント

If you choose something just because it looks cute, you may end up regretting it while you're traveling.

For women in particular, the following four points are important to keep in mind in order to minimize travel fatigue.

軽さ:階段や棚への上げ下げを考慮した「3kg以下」

There are surprisingly many situations where women have to "lift" suitcases, such as airport security checkpoints, stairs at train stations, and small steps in hotels.

Aim for a weight of 3kg or less: Choose a bag that weighs 3kg or less before being filled with anything. The lighter the bag, the more souvenirs you can pack in it, and it will also be easier to clear the weight restrictions of LCCs.

キャスター性能:移動の快適さを左右する重要パーツ

What is surprisingly overlooked is the stress of noise and the car moving on its own while traveling.

- Quiet operation for peace of mind even in the early morning or late at night: The silent casters make little rumbling noise, so you can walk without worry even in residential areas or hotel hallways.

- A stopper that's useful on trains: Holding your suitcase between your feet to prevent it from rolling around on a swaying train can be more tiring than you might imagine. With a stopper function that can be locked with just one finger, you can relax and enjoy reading or using your smartphone while traveling.

ストッパー:電車移動や待ち時間のストレスをゼロに

When you suddenly realize, "Oh, I left my mobile battery in there," or "It suddenly started raining, so I want to get out my folding umbrella," it can be embarrassing to have to open your suitcase on the side of the road.

・Accessible while standing: The "front-opening" design allows you to access the contents without opening the main compartment. This makes touch-ups and airport check-ins incredibly smooth.

収納構造:フロントオープン・拡張機能・内装ポケット

For a 4-day, 3-night trip, "easy access during transit" and "accommodating increased luggage on the return journey" are crucial.

[Front-Opening]

A design that allows you to access your laptop or makeup while the suitcase is upright. Convenient for "quick access" at airports and train stations. You won't have to lay your suitcase on the floor, avoiding awkwardness in public.

[Expansion Feature (Expandable)]

Peace of mind even if you buy more souvenirs on the way back. A single zipper increases capacity. A great feature that allows for compact travel on the way there and large capacity on the way back.

[Interior Pockets]

Dividers for organizing small items like underwear and cosmetic pouches are convenient. Your belongings won't spill out when you open the suitcase, and unpacking at the hotel will be smoother.

デザイン：旅のテンションを上げる見た目

A suitcase is part of your travel outfit.

- "Cute and mature" texture: If you choose a matte texture that is not too flashy or one with an elegant sheen, it will match any outfit.

-Interior design: The beauty of the contents is also an important point for women, such as a beautiful lining that makes you feel excited when you open it, or dividers that prevent your belongings from falling apart.
