FAQ: Suitcase lock trouble Q&A

1. Main reasons why suitcases cannot fit into coin lockers

Title

Many of the complaints about "I chose a small-sized suitcase but it didn't fit" are due to the difference in size standards between lockers and suitcases.
Here, we will look at the reasons for not getting in from three perspectives.

2. Misunderstanding the "external dimensions" and "internal dimensions" of suitcases

3. Casters or handles get caught

① Locker sizes vary depending on the station or facility

Title

There is no uniform standard for coin lockers across Japan.
For example, new lockers at major JR stations and airports are designed to be "deep and somewhat wide," but in older subway stations and regional stations, smaller lockers are often still available .

The type generally referred to as "small locker (300 yen)" is

The approximate dimensions are approximately 45cm high x 34-35cm wide x 55-57cm deep .

However, at some stations, the height is less than 40 cm , or there are stoppers or unevenness on the inside of the doors, so if the outer dimensions are just right, the doors will not close.
In other words, even if it's the same S size, it may or may not fit depending on the station .

Title

② Misunderstanding the "external dimensions" and "internal dimensions" of a suitcase

Title

When choosing a suitcase, you will see specifications such as "Capacity 20L" and "Height 45cm."

The thing to pay attention to here is the difference between the outer and inner dimensions .

The "size" indicated by many manufacturers is

Sometimes the height is shown only for the main body, excluding casters and handles.
However, when actually putting it in the coin locker,

You need to judge based on the overall height (=external dimensions) including the casters and handle.

·for example,

  • Body: Height 45cm
  • Caster + handle: +5cm

A model like this would be 50cm in total , which would not fit in a locker that can only accommodate 45cm.
Although it's only a difference of a few centimeters, the locker doors are surprisingly tight.

Before purchasing, make sure to check whether the dimensions listed are internal or external .

Title

3. Casters or handle protrusions get caught

Title

The suitcase design is also one of the reasons why it may not fit.
While recent models are highly functional, with features such as silent casters and double wheels, the casters can sometimes protrude significantly .

In addition, the storage position of the handle and the thickness of the front pocket can also make it difficult to fit inside the locker.
If you encounter a situation where the height fits but the depth is too tight and the door won't close, this protruding part is the cause.

When choosing, it is a good idea to measure the actual dimensions or check the "external dimensions (including casters)" on the manufacturer's website.

3. Three solutions when your suitcase won't fit in a coin locker

Title

"I checked the size, but when I put it in, the locker wouldn't close..."
Such problems are surprisingly common.

Here,

Here are three smart solutions you can take when your suitcase won't fit in a coin locker.

table of contents

1. Luggage storage and general information desks at stations

2. Find an empty locker

3. Use delivery services

1. Use the "luggage storage" or "general information desk" at the station

Title

First, the most reliable and safest option is to use the luggage storage service at the station .

Major JR stations, airports, and large commercial facilities may have manned counter-style baggage storage or cloakroom facilities.
Here, even if your suitcase is too large to fit in the lockers, the staff will carefully store it for you , so you can rest assured.

Some places we particularly recommend are:

  • JR East "Baggage Storage"
  • Shinkansen exit and "Baggage Service" counter inside the airport
  • Information center in a commercial facility

The fee is around 500 to 800 yen per day, which is a little more expensive than using a locker, but the advantage is that there is less risk of theft or damage .

Title

② Search for "available lockers" using the coin locker search app

Title

"I couldn't fit it in the lockers at this station, but there might be one at another exit."
A locker search app is useful in such situations.

Some popular apps and sites include:

サービス名 主な特徴
コインロッカーなび 駅ごとのロッカー位置・サイズを地図上で確認できる
BizSPOT（ビジスポット） 全国のカフェやコワーキングスペース内のロッカーを検索・利用可能
ecbo cloak（エクボクローク） カフェ・ショップ・ホテルなどの空きスペースに荷物を預けられる（予約制）

"ecbo cloak" is particularly convenient because it allows you to store your belongings in places other than lockers .
For example, you can leave your suitcase at a cafe near the station and then head off sightseeing or to a business meeting.

Using the app will significantly reduce the time you spend walking around looking for your locker.

Title

3. Send your luggage using a delivery service

Title

If you have luggage that you will not be using on the same day, we recommend using a delivery service to have it sent to your hotel or airport .

Delivery counters for companies such as Yamato Transport and Sagawa Express are located in train stations and commercial facilities, making it easy to send items as small as a single suitcase.

サービス名 特徴
ヤマト運輸 空港宅配サービス 空港カウンターに当日または翌日にお届け
JR東日本 宅配便サービス 駅構内の窓口で手続き可能
ホテル直送プラン チェックイン前にホテルに荷物を届けられる

This way, you don't have to carry a suitcase while sightseeing or attending meetings, and you can go out hands-free .
This is especially convenient for business trips or multi-city trips.

Title

💡 Quick Tip: Don't force your luggage into the locker if it won't fit

"Just a little bit more," I thought, pushing in with more force.

There is a risk that the casters or body may be damaged inside the locker.
Also, if you lock the locker when the door is not closed, it may become impossible to open .

If you feel like your belongings won't fit, the best thing to do is to simply look for another locker or storage area.
