Hi all --
Quick question, if you in advance reserve to stay more than 1 night at a capsule hotel, will they let you store your bag there in the time after check out after the 1st night? (since you're going to be there the next night)
you should call/email/text them and check (each hotel can have slightly different policy)
in general, capsule hotels would keep bigger bags behind the counter. most hotels require you to leave (and remove all belongings) from the capsule from 10am-2pm (so that they can clean everything). some allow you to hold onto the tiny locker for your whole stay, some don't
to scope out lockers at train station, one trick I've found is to use google maps.
here, you can see that there are lockers, likely 100 coin + key type, not suica
