Traditional Japanese foods/meals that are cheap to buy in America?

Question:

Answer:

Yakisoba pan (not that traditional but this one is the cheapest one on the list)
Gyudon
Oyakodon
Cha soba/zaru soba
Yakimeshi/chahan

Udon/soda/ramen are usually pretty inexpensive
Kakiage don usually won't cost that much
Okonomiyaki is a little iffy but there are cheap ones around
Katsudon usually don't cost that much and there are some cheap ones around
Omurice usually don't cost that much and there are some cheap ones around

Everything above are meal sized servings. If you go to the right places, everything on the list should cost about the same as a combo (if not less) at most fast food places.
