一、コインロッカーにスーツケースが入らない主な原因

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.

1. 駅や施設によってロッカーサイズが違う

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 .

2. スーツケースの外寸で確認していない

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 .

3. キャスターやフロントポケットが干渉する

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.

二、日本のコインロッカーサイズ早見表

The coin lockers installed at stations and commercial facilities vary slightly depending on the railway company, but
Here we have compiled a list of typical sizes based on official information from the Keio Line and Inokashira Line.
If you want to check in a suitcase, it should be standard size or larger .

各サイズの目安と料金

サイズ区分 寸法(mm)幅×高さ×奥行 1日貸し料金(目安) 収納できる荷物の例
小（Small） 130 × 320 × 575 約300円 ハンドバッグ・リュックなど

多くの駅では「標準」または「中」サイズのロッカーが最も多く設置されています。
スーツケースを預けたい場合は、高さ57cm以内、幅34cm以内が目安です。

三、コインロッカーに入らないときの対処法

If your suitcase won't fit in a coin locker, there are ways to deal with the situation calmly without panicking.

Here are three helpful solutions to help you out in such situations.

It's a good idea to think about which method you will use in advance in case of unexpected problems.

1. 手荷物預かり所を利用する

The most reliable and safe method is to use the baggage storage facilities located at stations and facilities.

• Safety : Unlike coin lockers, luggage storage facilities have staff who carefully manage your belongings.

• Conditions for storing items: When using the storage facility, the fee is slightly higher than for lockers, but in return, there is a lower risk of damage to your stored items, and fewer problems.

Typical childcare facilities :

・JR East "Temporary Luggage Storage" : Available at Shinkansen exits and major stations.

• Airport "Baggage Service" counter : There are counters within the airport that offer baggage storage services.

• Information centers in large commercial facilities : You may be able to leave your luggage at shopping malls or department stores.

The storage fee is approximately 500 to 800 yen per day . The fee varies depending on the facility and location, but if your luggage won't fit, you should definitely use it to avoid the risk of theft or damage.

2. ecbo cloakを利用する

"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
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.

3. ホテルや空港へ配送する

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

Price example :

・Yamato Transport Airport Delivery Service : For delivery from the airport to Tokyo, it costs approximately 1,000 to 2,000 yen per package (depending on size and delivery destination).

・JR East's courier service : For courier services within train stations, the estimated cost from Tokyo to other regions is approximately 600 to 2,000 yen (depending on the size of the package and the destination).

Using a delivery service eliminates the need to carry suitcases, allowing for greater freedom of movement. However, the process can take time, so it's recommended to ship your luggage well in advance.
