Japan's coin locker system is one of the most useful pieces of infrastructure for travelers. Coin lockers (コインロッカー) are available at virtually every train station, allowing you to store luggage for the day while sightseeing without dragging it everywhere. Understanding the system — sizes, prices, payment methods, and where to find lockers when they're full — makes multi-city travel significantly more comfortable.
Where to Find Coin Lockers
Every major train station in Japan has coin lockers — often many sets of them. At large stations (Tokyo, Kyoto, Osaka, Shinjuku), there are multiple locker banks in different locations: near ticket gates, in basement levels, near bus terminals. When one area is full, another bank elsewhere in the same station often has space.
At popular sightseeing areas without a station (Arashiyama's main tourist area, Nara's deer park entrance), lockers are available at the nearest station or at local shops offering luggage storage services.
Sizes and Prices
Lockers come in standard sizes:
Small (S): Fits a small backpack or personal bag. ¥300–¥400/day.
Medium (M): Fits a cabin-size carry-on or medium backpack. ¥500–¥600/day.
Large (L): Fits a standard check-in suitcase (up to 70cm). ¥700–¥900/day.
Extra-large (LL): For oversized luggage or ski bags. ¥1,000–¥1,200/day.
Charges are per day (typically midnight to midnight or 24 hours from use), not per hour. Leaving luggage for a second day requires paying again. Lockers that reach 72 hours overdue are typically unlocked and items moved to storage — collect promptly.
Payment Methods
Older lockers: ¥100 coins only. Bring plenty of coins.
Modern lockers: IC card (Suica/Pasmo) payment accepted — tap to store, tap to retrieve. Most new locker installations in major stations accept IC card. No change needed; the balance is deducted automatically.
Some modern systems use a QR code or PIN printed on a receipt rather than a physical key. Keep the receipt until you retrieve your bags.
When Lockers Are Full
On peak travel days (Golden Week, cherry blossom weekends, holidays), lockers at famous stations fill quickly. Strategies:
Search different station areas: Major stations have multiple locker banks — check near all exits and at basement levels.
Nearby stations: Walking one or two stops to a less-trafficked station often finds available lockers even when the main tourist station is full.
Luggage storage services: ecbo cloche (app) and Klook partner with shops and facilities across Japan to provide luggage storage. The apps show real-time availability and are useful when station lockers are full.
Hotel luggage storage: Most hotels store luggage before check-in and after check-out free of charge for guests — a useful alternative to coin lockers.
Practical Tips
Measure your suitcase before going — the locker size descriptions are strict. A standard 65L spinner suitcase requires at least a Large locker. Take a photo of your locker number before walking away. Keep your IC card or coin locker key easily accessible. Don't store perishables, electronics in extreme heat, or valuables beyond casual security needs.
