Luggage lockers at Nagano Station 36 hours?

Hello, we want to leave our two suitcases in the lockers at Nagano station, possibly from 10am in the morning to approximately 13.00pm the next day...can you store luggage for more than 24 hours in these lockers? Thankyou

Luggage lockers can generally be used for up to 3 calendar days. If you put it in on day 1, you should remove it by the end of day 3.

While three days is the maximum use time of many lockers, some stations/locker banks have shorter periods, some clearing out leftover items once a day, so you'll probably want to confirm with the specific locker you're planning to use.
