What is the difference between tonkatsu, katsu , okonomiyaki, takoyaki and yakisoba sauce?

Tonkatsu sauce and katsu sauce are the same thing and used interchangeably.

Takoyaki and okonomiyaki sauce are very similar.  Okonomiyaki has a thicker consistency while takoyaki is thinner and lighter in taste. Compared to tonkatau sauce, these sauces are sweeter.

Yakisoba sauce is used for yakisoba noodles.  It is more sour and has a stronger Worcestershire sauce flavor to it.
