Yokohama is a city near from Tokyo. You can go there by train in 30 minutes or so. Many noted beautiful places are in there, Yokohama people are very proud of their town;)
I went to Yokohama red brick warehouse. The warehouse was built in 1907, it was of course warehouse at first. then became US army headquarters when WW2 was over. after that, became warehouse again. Now, there is not. there are many foods, clothes, zakka shops!
You can enjoy shop cruising and imagine history of the warehouse.
