How big are storage lockers at Tokyo Station?

There are three general sizes as follows: Small 35cm x 34cm x 57cm, Medium 57cm x 34cm x 57cm, and Large 117cm x 34cm x 57cm. Side note if you need a larger locker, you need to get to it early as these can be all occupied by 11am.



Storage lockers at Tokyo Station—known as "Coin Lockers"—typically come in four standardized sizes to accommodate everything from a small purse to a large international suitcase. Small (S) lockers are roughly 34cm x 34cm x 57cm, perfect for day bags or souvenirs. Medium (M) lockers measure about 55cm x 34cm x 57cm, generally fitting a standard carry-on suitcase. Large (L) lockers are approximately 84cm x 43cm x 57cm, designed for large check-in suitcases. For oversized items, Extra Large (LL) lockers can go up to 177cm x 57cm x 57cm, though these are much rarer and found only in specific "Locker Areas" like the Marunouchi or Yaesu underground passages. In 2026, most of these lockers utilize IC cards (like Suica or Pasmo) for payment instead of actual coins. If the lockers are full, you can use the Sagawa Luggage Storage service within the station, which accepts larger items for a flat daily fee regardless of their specific dimensions.
