Previously, I wrote about yohshoku [1], or Japanese-style western cuisine. Prompted by a question from Elise, I've done a bit more research on this. (Much of this is gathered from a book in the Just Look Just Cook cookbook series from Yomiuri Shimbun Co., called "Yoshoku in Japan". (Note that it can be spelled Yohshoku or Yoshoku.))
There are two types of Western-style cooking in Japan. One is the authentic kind, that is available in real French, Italian, etc. restaurants. The other kind is the type of western-style cooking that has been adapted to Japanese tastes, and into Japanese homes as part of everyday cooking. Japanese people are very adept at adopting a foreign culture and making it part of their own, and food is no exception. In general, yohshoku can be classified as western-style food that has been changed and adapted so that it fits well with rice rather than with bread - thus making it uniquely Japanese.
Here are the basic ingredients used for yohshoku.
