tokyo metlocker plus

You probably already know about this, but I recently learned about these lockers that will send your luggage to your hotel

The lockers are located in several metro stations around Tokyo.

Apparently if you put your luggage in these lockers by 14:00, they will be delivered to your hotel by about 19:00 the same day

I think this would be good to use if you land in Tokyo too early for check-in and don't want to lug your bags around
