I recently returned home to Hawaii from Japan. Japan was very cold. I bought a down coat on the internet from LL Bean before I went. I was very happy that I had that coat.
This was my second trip to Japan this year. This time I stayed for 10 days. When I went to Japan in September I stayed for 3 weeks.
I spent the first couple of days in the Yokohama area. I stayed at a hotel close to the Yokohama station. Yokohama station is very crowded and very confusing.
Before I left Hawaii I bought a one week JR rail pass. When you purchase the pass you get only a voucher. When you arrive in Japan you must go to the green room to convert your voucher to the pass. I asked serveral people in the Yokohama station where I could exchange my voucher. I never did really understand where to go. I finally took the subway to the Shin Yokohama station. I have been to Shin Yokohama station many times and know it very well.
