一、修学旅行にスーツケースは必要？

While referring to the information provided by the school,

Keeping the following three points in mind will ensure a smooth journey from departure to return home.

修学旅行でキャリーケースは禁止？

Once you pack your belongings, your suitcase can become surprisingly heavy.

It's important that the bag has features that make it easy for even students with less strength to carry.

  • Double casters: The 8 casters (2 on each corner) provide stability and smooth movement even on train platforms and uneven roads.
  • Lightweight body: Since there are many situations where you need to lift it yourself, such as going up and down stairs or loading it into the luggage compartment of a bus, the lightness of the unit itself is a major advantage.

ボストンバッグとスーツケースはどちらがおすすめ？

First, check the size restrictions (height and width limitations) specified by the school.

The general guidelines for the number of nights you should stay are as follows:

  • 2-night, 3-day trip (S size / 30-40L): A standard size for domestic travel. A carry-on compatible model will reduce waiting times at airport baggage claim.
  • 3 nights or more (M size / around 60L): This spacious size is suitable for trips to Hokkaido, Okinawa, and other places where you'll need to pack lots of clothes and bulky souvenirs.

Recently, an increasing number of school trips use bullet trains and airplanes, meaning students often have to carry their luggage for long periods.

As a result, more junior high and high school students are choosing suitcases for their trips.

二、修学旅行のスーツケースは何サイズがいい？

Modern suitcases are not just for carrying luggage,

It is designed with many ingenious ideas to eliminate inconveniences while traveling.

We will introduce some features that will be especially useful for the digital native student generation.

修学旅行のスーツケースは何Lが目安？

Many people are unsure whether to use a Boston bag or a suitcase for school trips.

Both have their advantages.

宿泊数 容量目安
1泊2日 20〜30L
2泊3日 30〜40L
3泊4日 40〜50L
4泊5日 50〜60L

Important point:
Capacity (L) and external dimensions are different. Even if a product is listed as "60L," its external dimensions may exceed school regulations (e.g., "height 65cm or less"). Always check the "External Dimensions (cm)" in the spec sheet before purchasing.

2泊3日の修学旅行

Standard: 30-40L

This is the number of nights typical for popular domestic routes such as Kyoto, Hiroshima, and Tokyo.

Many people assume that "30L is enough for 2 nights," but there's a catch here.

📚 Editor's note:
For fall and winter school trips, outerwear can be bulky, so a 30L bag may already be full on the way there. While 30L might be sufficient for spring and summer, for fall/winter trips or if you plan to buy a lot of souvenirs, it's safer to choose a 40L bag.

3泊4日の修学旅行

Estimated capacity: 40-50L

This capacity is typically used for school trips to distant locations like Hokkaido, Okinawa, or Kyushu, which often involve multiple nights.

Many people choose "60L" here, but the editorial department recommends 40-50L.

📚 Editor's note:
A lighter 40-50L suitcase is easier to manage throughout your trip. If you're concerned about souvenirs on your return journey, consider a model with an "expansion function" – it'll be compact on the way there and can be expanded only for the return.

4泊5日の修学旅行

Estimate: 50-60L

This capacity is suitable for extended trips or international travel.

For optimal comfort, when choosing a 50-60L model, select one with a body weight of 3.2kg or less.

📚 Editor's note:
Even if you have plenty of room for your luggage on the outward journey, a large suitcase in itself becomes a burden to move around. It is more realistic to keep it within 60L and secure extra space for the return journey with an expansion feature.

We've compiled a list of frequently asked questions from students and their parents who are using their own suitcase for the first time.

Caster Stopper

  • This is a convenient feature for school trips that involve frequent travel on bullet trains and buses.
  • It prevents your suitcase from moving around on its own inside the vehicle.

USB Ports
