Let's have a relaxing day in Tokyo. We can enjoy breakfast at China town in Kanagawa-ken, do some shopping at Ginza area, enjoy an afternoon on a beach at Kamakura Island and end the day by having a drink at a rooftop bar.
We can also do anything else, if you prefer museums, Universal studios, parks, we can go there instead. It's up to you! I will just try to make your experience as local resident as possible:-)
