That's true - there are many different kinds of Japanese food, so don't think automatically think you have to eat with chopsticks in a Japanese restaurant! It really depends on what you order.

But they're not going to be offended if you just eat everything with a fork or spoon anyway. They know that not all westerners can even use chopsticks, so unless you're in a particularly snooty Japanese restaurant, you shouldn't have any problem. They might look down on a *Japanese* person who fails to use chopsticks when convention suggests it, but they're not going to care about a westerner.
