Yokohama has progressed over the years because of its port location. It's a metropolitan city with quieter aspects from Tokyo. There's a nice downtown street with boutique shops, both local and foreign. There's also an old brick warehouse which from the facade you wouldn't think anything of it. On the inside, though, is this shopping warehouse full of local vendors and fun eats.
If you've exhausted Tokyo and want a slight change of pace, Yokohama is an option for a day trip to another city calmer than the bustle of Tokyo.
