What is the size of train station coin lockers and availability?

Great question! From my experience traveling all over Japan, coin lockers at train stations come in three basic sizes: small, medium, and large. Even the smallest lockers are usually big enough to fit a standard suitcase, which surprised me the first time I checked. I actually measured some before to be sure because these lockers are super popular and sometimes hard to find during busy travel seasons.

Here’s a quick rundown of what you can expect:

• Small lockers: Roughly 35 cm x 34 cm x 57 cm (about 14" x 13" x 22"). These fit a carry-on sized suitcase or a backpack comfortably.
• Medium lockers: Around 35 cm x 57 cm x 57 cm (14" x 22" x 22"), good for slightly bigger luggage or multiple bags.
• Large lockers: Close to 57 cm x 57 cm x 57 cm (22" x 22" x 22"), perfect for big suitcases or bulky items.

Prices usually depend on the size, ranging from about ¥300 (~$2.20 USD) for small, ¥400 (~$3 USD) for medium, to ¥600 (~$4.50 USD) for large lockers. You pay for usage typically up to 24 hours, so if you need it longer, you’ll have to pay again.

What if all the lockers are full when I arrive at the station?

This happens often, especially at busy stations like Tokyo or Osaka during rush hour or holiday seasons. Japanese people often arrive early to secure lockers for day trips or sightseeing. If you find lockers full, some stations have multiple locker areas—check both sides of the platform or entrances. Also, look for coin locker areas near shopping malls or bus terminals connected to the station.

If still no luck, many stations now offer luggage storage services or “takkyubin” (delivery services) that can send your bags ahead to your hotel or next destination. It’s a bit pricier but very convenient if you want to explore hands-free.

Are there coin lockers that accept credit cards or just coins?

Traditionally, coin lockers only take coins (¥100 or ¥500 coins mainly). But lately, some big stations have upgraded to electronic lockers that accept IC cards like Suica or Pasmo, or even credit/debit cards. These are super handy if you don’t have the right change.

However, these advanced lockers aren’t everywhere yet—mostly in major urban hubs. So, carrying some coins is still a good idea if you’re traveling to smaller or rural stations.

Can I leave my luggage overnight or for several days in a coin locker?

Usually, coin lockers allow a 24-hour usage period. If you keep your luggage longer, the locker may automatically open, and your belongings could be removed by station staff. Some stations might charge extra fees for longer storage, but it’s not common.

For longer-term storage, look for dedicated luggage storage counters or lockers in airports and major stations. They are a bit pricier (around ¥500 to ¥1,000 per day, or $4.50-$9 USD), but safer and more reliable.

Do Japanese people use coin lockers often?

Absolutely! Coin lockers are a daily convenience for many locals, especially commuters and shoppers. For example, I frequently use a locker near my work station to leave bulky items or shopping bags before heading home. During festivals or sightseeing trips, it’s common to stash your luggage so you can enjoy walking around without dragging suitcases.

Japanese culture values efficiency and neatness, so coin lockers help keep stations clean and travelers unburdened. It’s a practical solution that fits well with how we live and travel.

In summary: Coin lockers are a staple of Japanese travel life, and even the smallest size can fit standard luggage. Prices are reasonable and vary by size. If you can’t find one right away, check different locker spots or consider luggage delivery services. Having some coins ready is helpful, but major stations are slowly catching up with card payments. For longer stays, dedicated luggage storage is a better bet. This system reflects the Japanese love for order and convenience—even in everyday things like storing your bags!
