Thank-you, Queen's Square mall in Yokohama! I stopped at Starbucks there last night to fortify myself caffeine-wise before the long plenary. I must have left my wallet there. I didn't realize this until this morning putting stuff in my bag. I went to the hotel desk first where they put the words "lost black wallet" etc. on a piece of paper. I took it to Starbucks, where they seemed to say they had found it, and I should go to Information. The Information lady called around and told me to go to security. At security, they simply handed it to me and asked me to sign my name in their register! Not a single yen was missing.
