Which Airports We Track
LuggageSnap shows live counts for the locker banks on the Multi-Ecube network — the reservable smart lockers that replaced JR East's To Locca service. That covers the main terminal banks at Narita and Kansai, the Tokyo Monorail stations at Haneda, Itami and Okadama. Each airport also has additional lockers and staffed counters that are not in our live feed, so a full bank here does not always mean the airport is out of space.
Narita Airport Lockers
We track the Terminal 1 and Terminal 2 banks, both outside the gates. Narita runs two pricing systems side by side. Day-rate lockers — most of Terminal 1 and the upper floors of Terminal 2 — cost roughly ¥400 / ¥600 / ¥800 for small, medium and large, and a new day starts at midnight, so an overnight stay costs two days. The time-rate lockers in the Terminal 2 basement and in Terminal 3 charge a flat fee for the first six hours (about ¥300 / ¥500 / ¥600) and then add a charge every 24 hours — much cheaper for a short layover. Maximum stay is 8 days. Cash and IC cards such as Suica are accepted.
Narita Station is not Narita Airport. It is a town station roughly ten minutes away by train. If you are flying, store your bag in the terminal.
Haneda Airport Lockers
The banks we track at Haneda are inside the Tokyo Monorail ticket gates at Terminals 1, 2 and 3 — convenient if you are already riding the monorail, useless if you are not, because you cannot reach them without tapping through. The terminal buildings themselves also have lockers outside the gates, priced around ¥400 / ¥500 / ¥600 per day with ¥1,000 oversize units, and you may keep a bag for up to 7 days counted in 24-hour blocks. Staffed baggage counters run 08:00–19:30 at Terminals 1 and 2, and 24 hours at Terminal 3 — the right choice for skis, surfboards or anything that will not fit.
Osaka Area Airports
Kansai is the best-covered airport in our data, with banks in Terminal 1, Terminal 2 and the Aero Plaza building. Day-rate pricing is about ¥400 / ¥600 / ¥800, switching over at midnight; Aero Plaza carries no small lockers. Because the banks are spread across three buildings, one being full rarely means you are stuck — check the live counts above before you walk.
Itami, Osaka's domestic airport, has banks at the North, Central and South terminals. Okadama in Sapporo has a single bank on the first floor.
Before You Walk to a Locker
Lockers fill fastest in the middle of the day. Across our six months of Japanese locker records, the busiest hours are 11:00–14:00, and the quietest are before 10:00 and after 18:00 — the same pattern at airports and city stations alike. If you land in the morning and plan to explore before an evening flight, store your bag as soon as you clear arrivals rather than coming back at lunchtime.
Measure before you choose a size. Large (L) lockers take a standard checked suitcase, medium (M) fits cabin-size, and small (S) suits a backpack or shopping bag. Oversize units exist at Haneda and Kansai but are rare — if you are carrying something genuinely large, a staffed counter or a delivery service is the safer plan.
