Specifically, we’ll be talking about the Metro Commerce Corporation’s online service, the “Locker Concierge”, which started operations on March 29, 2019.

By visiting their website (https://metro.akilocker.biz/index.html?lgId=tokyometro), you can check the availability of any of the lockers within the stations no matter how far you are.

Not to mention the service is completely free! It supports five different languages as well (English, Simplified Chinese, Traditional Chinese, Korean, and Japanese), so even foreigners can use it smoothly.

As of September 2023, over 40 major stations can be checked through the website, including: Akihabara, Akasaka, Ebisu, Ginza, Hibiya, Ikebukuro, Nihombashi, Oshiage <SKYTREE>, Roppongi, Shibuya, Shinjuku, Shimbashi, Tokyo, and Ueno Stations.

1. From the main menu, choose which station you want to use the coin lockers for. You can switch between languages anytime on the upper-right corner of the page.

2. On the “Station Map” page, the locations of the coin lockers as well as their availability will be displayed. Furthermore, you can sort them based on the size of the lockers.

3. On the same page, touch the locker you want to book on the right side, and you’ll be shown more detailed information on the availability of the lockers.

This service will be useful to avoid troublesome situations like luggage not fitting in to the locker you found or bringing your suitcases around as you look for lockers.
