We have 2 kind of teppanyaki in Japan. 1. Famous teppanyaki in the world: chef cooks in fr of customer. In this case we eat meat, vegetables, fried rice (like a chahan style as Dag mentioned
2. Traditional teppanyaki in Japan: Okonomiyaki and Monjayaki. Okonomiyaki is pancakes w.meat, seafood and vegetables. Monja is also pancakes but more liquid w.meat, seafood and vegetables. I think Okonomiyaki is coming from Kansai/hiroshima and monja is from kanto.
In those restaurants, no fried rice. Some offer yaki onigiri!
Teppanyaki = steel plate (teppan) + fry (yaki).. An assortment of different dishes, which include beef, shrimp, squid, octopus, okonomiyaki (a kind of filled pancake) and, yes, fried rice..
