If it is a buffet then I leave 10%. If I am getting served then I leave 20% unless they are terrible then it drops to 15%. Hope that helps.How much to tip at a Japanese Hibachi type restaruant?

i work at a hibachi/sushi restraunt and i am a hibachi cook in trainning and a good tip would be anywhere between 15-20% like you said and yes it is customary to tip your hibachi cook extra personally because just a plain tip gets split between the waiter and the hibachi cook. So yeah hibachi cooks like it when you tip them a little extra personally. Well in the restraunt i work at the hibachi cooks tip all depends on if they did a good job on their hibachi show and if they pleased the customer with casual conversation and such (like $20 or so if it was pretty good, but our reastraunt is in a somewhat small town so it might be higher depending on where you live) plus the 15-20% regular tip which the waiter gets part of.
