A: It’s hard to name just ONE most popular food, but I think I can narrow it down to three.
1.) Seafood, including all kinds of fish, shrimp, squid, and octopus.
2.) Noodles. Japanese styles of noodle include udan, soba, ramen, and buckwheat, and they are usually eaten in a broth and topped with other good things like pieces of seafood, meat, tofu, green onion slices, mushrooms, or other vegetables.
3.) Rice.
