Ramen
Definitely, Ramen! Ramen (Noodle with soup) is one of the most popular foods in Japan, it has some pork or vegitables on top of noodle. Basically, you have a soup choice of miso (red bean paste) or shoyu (soy souce) and can eat with reasonable price. I would say try going to Ramen shop where people are standing in long line, it would be worth it!
