Do you know what is a real Japanese cuisine?

Recently we can find many tourists around my office. They come from Asia and other countries. They say that the purpose to visit Japan is having Japanese cuisine. I'd like to introduce some real Japanese cuisine to foreigners who want to know the real. The real Japanese cuisine is expensive. This is one reason. They don't receive so many reservations, because they think if they can't offer the best services.

Please enjoy the real taste of ingredients.

I guess these food is a particular of Japan.
