If you're visiting Tokyo, don't overlook the large city of Yokohama. This port town also has the largest Chinatown in Japan, as well as the Nissin Cup Noodle Museum. It's easily reachable by rail.
Head out to Yokohama if you haven't and explore the bay. Lots of cool architecture and good places to eat!
One of my new favorite sushi places. Mostly for the service! The assortment of rolls are quite extensive with all sorts of combos. The fish was super fresh and we got this uber delish spicy tuna veggie roll not even on the menu!
Pleasant seaside city with large boulevards and a bit more greenery than its larger neighbor. China Town (chukagai) is probably the highlight for most visitors. Nice but lower priority vs. other attractions in the region.
