I have planned to visit Japan on Apr 9-16. The first 4 days, I planned to go to Kawaguchiko and Hakone before come back to stay in Tokyo for the last 4 days at Shinjuku area.
So, I would like to leave one of my luggage at the Shinjuku station for the first 4 days. I though the coin locker is applicable for 3 days and the officer will empty the locker. Where could I take my luggage back? Does the service fee for the day 4 is the same rate or any extra fee will apply?
Alternativly, are there any luggage room/storage in the Shinjuku station that I could leave my luggage for 4 days? Where is it and how much it cost? Thank you in advance for the answer. :)
