一、二人旅行ではスーツケースを何個用意する？

When choosing the best suitcase for two people traveling together, you need to consider a few points, taking into account the amount of luggage you will be carrying and your travel style.

When packing luggage for two people into one suitcase, important factors include size, capacity, lightness, and storage functionality. Here we will introduce some tips for choosing the perfect suitcase for two people traveling together.

大きなスーツケース1台の場合

The most important thing when traveling with someone is to choose a suitcase that is the right size to fit all your luggage. It's important to pack lightly, but if you're traveling for a long time or bringing a lot of luggage, you'll need a suitcase with the right capacity.

  • Medium (M size) : Perfect for a week-long trip. Even if you have a lot of luggage, it can easily fit clothes and necessities for two people.
  • Large (L size) : Recommended for long trips of a week or more, or for bringing thick clothing appropriate for the season. It can comfortably store luggage for two people.

Also, having extra space in your suitcase will allow you to easily store any souvenirs or extra items you may have purchased during your trip.

When carrying a suitcase while traveling, lightness is a very important point. Since you will be carrying luggage for two people, if the suitcase itself is heavy, it will be difficult to move around. Especially considering that you will be walking for long periods of time at airports and stations, a suitcase that is lightweight and easy to carry is ideal.

  • Lightweight polycarbonate and ABS materials are strong yet relatively lightweight, making them easy to transport while traveling.

2点セットがおすすめな理由

When traveling as a couple, you often have to leave your suitcases at the airport, so security is also a consideration. A suitcase with a TSA lock (a lock approved by the U.S. Transportation Security Administration) is highly secure and provides peace of mind during your trip. Choosing a suitcase with a TSA lock is especially convenient if you're traveling internationally or using multiple airports.

二、二人旅行用スーツケースの選び方

When choosing the perfect suitcase for a two-person trip, ease of use is just as important as capacity and functionality. Here, we'll introduce some recommended suitcases from New Trip . Take a look at the features of each and find the model that's best for you.

サイズ・容量

This set is appealing because it gives you peace of mind knowing that you won't have to worry if you end up with more souvenirs on the way home.

Choose from three sizes (S/M/L) to find the perfect combination for your trip.

If you have a two-piece set, you can use one larger bag for shared luggage,

and the other smaller one as a secondary bag.

2台でも移動しやすい軽量性

For couples traveling by train or bus, the "0701 Plus" with its stopper function is ideal. The lightweight hybrid material makes it easy to carry the often heavy luggage of two people.

キャスター性能

When moving two items side-by-side, the performance of each caster is crucial.

  • 360-degree rotation: Easy to change direction and move smoothly
  • Quietness: Considerate to others when moving in hotels or at night
  • Stability: Less likely to wobble even on slopes or uneven surfaces

For trips that often involve early morning or late-night travel, models with silent casters offer peace of mind.

収納のしやすさ

When traveling with two people, clothes and small items can easily get mixed up, making it hard to tell whose belongings are where.

  • Models with ample dividers and pockets make organization easy.
  • With an expansion feature, you can accommodate extra souvenirs on your way back.
  • A front-opening feature allows you to quickly retrieve necessary items while on the go.

デザイン・カラー

When purchasing a two-piece set, design and color selection are also important.

  • Matching colors: Creates a unified and stylish look
  • Different colors: Allows you to easily identify your suitcase
  • Utilize name tags: Makes your luggage easier to spot at airport baggage claim

Choosing different colors from the same series allows you to maintain design consistency while making your luggage easier to identify.

三、二人旅行におすすめのスーツケース2点セット

Here are some tips for packing and luggage management to make traveling for two smoother and more enjoyable.

1. Distribute weight by "sharing luggage".

Tip: Put "shared items" like hair dryers, power adapters, and guidebooks into one person's suitcase. Instead, leave a little extra space in the other person's suitcase to store any souvenirs you might buy during your trip.

2. Place the "emergency kit" in one of your carry-on bags.

Tip: To prepare for the possibility of lost luggage or travel before and after hotel check-in, pack a day's worth of underwear, toiletries, and any necessary medications in one of your carry-on bags.

3. Distinguish by color, connect by tags

Tip: To prevent mix-ups, choose different colors or attach matching suitcase straps or luggage tags. Being able to tell at a glance that your luggage is yours, even from a distance, will help reduce stress in crowded airports.

4. Use compression bags to create space for souvenirs on the way home.

Tip: Even if you have plenty of room on the way there, you'll likely be stuffed with souvenirs for two people on the way back. Just pack a few compression clothing bags and your packing for the trip back will be dramatically easier.

四、二人旅行で荷物を分けるコツ

When packing for two people, the key is not to simply halve the luggage, but to create some space by sharing and allocating. Choosing a suitcase that suits both of your styles will help you achieve that space.

Simply having an easy-to-use, stress-free companion will transform your travel time into something more free and enjoyable. Pack plenty of special memories for the two of you with your ideal setup.

Method 1: Separate by Item Type

  • Suitcase A: Clothes, daily necessities
  • Suitcase B: Shoes, cosmetics, electronics

Separating by item type allows you to quickly retrieve what you need. Since electronics and cosmetics are often taken out, it's even more convenient to consolidate them in a front-opening model.

 

Method 2: Adjust for Outbound and Return Journeys

  • Outbound: Keep both suitcases 70-80% full to allow for space
  • Return: Ensure space for souvenirs

Especially for destinations where shopping is enjoyable, such as Korea, Taiwan, and Europe, it's important to allow for extra space, anticipating an increase in luggage on the way back. Models with an expansion feature are convenient as they allow you to increase capacity only for the return trip.

五、よくある質問（FAQ）

Q1. 二人旅行ではスーツケースは1つと2つ、どちらが良いですか？

A1：
・2泊3日程度の短めの旅行 → 1つでも十分にまとまります。移動がとても楽です。
・4泊以上 / 荷物が多い旅行 → 2つに分けると整理しやすく、重さの分散にもなります。

また、スーツケースを2つに分けることで、片方が万が一破損・遅延しても全荷物が失われないというメリットもあります。

Q2. 二人旅行におすすめのスーツケースのサイズは？

A2：目安は以下を参考にしてください：
・週末〜3泊 → Mサイズ（約50〜60L）
・1週間前後 → Lサイズ（約70〜90L）

「S + M」や「M + L」など、二人でサイズ違いの組み合わせが最も使いやすいです。

Q3. 液体類（シャンプー・ボディケア）は現地調達でも問題ありませんか？

A3：基本的には現地調達で問題ありません。
国内旅行であればホテルやコンビニで揃います。

ただし、常備薬・愛用している化粧品は必ず持っていきましょう。

Q4. 二人の荷物を一つのスーツケースにまとめると、ぐちゃぐちゃになりませんか？

A4：仕分け方法次第で、整理は簡単に保てます。おすすめは：
・各自の荷物を仕分けポーチにまとめる
・使う順番に上から配置する
・圧縮袋は必要最低限（重くなりやすいため）

「役割で分ける」意識があると、取り出しやすくなります。

Q5. 航空会社の受託荷物制限で気をつけることはありますか？

A5：特に重量に注意してください。
二人分を1つにまとめると、簡単に規定（多くは23kg）を超えます。

旅行前に航空会社の公式サイトで
「受託手荷物（checked baggage）」のページを確認しましょう。

Q6. 二人セットのスーツケース（2点セット）は本当にお得ですか？

A6：旅行の頻度が高いカップルやご夫婦には、非常にメリットがあります。
・サイズを旅行ごとに柔軟に使い分けられる
・色やデザインの統一感がある
・単品より価格が抑えられる

とくに、New Trip の拡張機能 / ストッパー / 耐衝撃アルミフレームは、二人旅で便利なポイントです。

Title

六、まとめ

When traveling as a pair, it is easier to move around and manage luggage if you split it into two bags instead of consolidating it into one.
