I’m not asked that often about this but it does come up. Particularly for those who are in Japan for skiing or visiting a remote town and returning to a major city weeks later – the question of “Where can I keep my suitcase for a few weeks?”
Locker storage at train stations and airports is the usual option for shorter term luggage ( you can also use the Echo app to find out options close by.).
So here are some options for longer term luggage storage in Japan.
Use the website Vertoe – this website will show you availability as well as pricing.
It is also possible to book online and then storage your luggage at one of the larger post offices in Japan.
If you’re simply looking for help on forwarding luggage in Japan, see my “moving you and your luggage in Japan” post here.
