My family of 4 use a coin locker in Shinagawa to store our 1 lugguage and 1 backpack. We had to leave for Hiroshima but the locker is stuck ( won't open even with the green light on) and we had to leave behind the contents or missed our Shinkansen train. We have a 16 days initiary and will move around Japan every 2-3 days. Questions: 1. How can we get our belonging back? 2. Can the contents be ship to our next destination?
