The three restaurants in Japan are now two. Teppan Edo is virtually the same as Teppanyaki. The grills have been updated and there is a wider "lip" for your plates and a smaller grill surface. It is much safer for children now, but there is no room to keep your saki warm. The food was pretty much the same as it was last year under the old name.
Tokyo Dining combines the old sushi bar area with the old cocktail lounge and has opened everything up. It is modern, trendy and quite loud. I did not eat there, so I can't say anything about the food.
