Mondō Muyō (問答無用 - No Discussion)

Mondō Muyō

To mean that discussion is pointless, you can use the four-character idiom 'mondō muyō' (問答無用).

'Mon' (問) means "question," 'dō/tō' (答) means "answer," 'mu' (無) means "no" or "nothing," and 'yō' (用) means "errand" or "need."

Therefore, 'mondō' (問答) means "questions and answers," 'muyō' (無用) means "unnecessary," and the combination means "unnecessary discussion."

This idiom is often used to end a wasteful discussion forcibly.

[Example of use]

'Ryokō saki wa kanojo ga mondō muyō de kimeta' (旅行先は彼女が問答無用で決めた - "My girlfriend decided the trip destination with no discussion").

  "leaving no room for _____" -- this phrase supports the "forcible" nature of this idiom. I don't know if forcible is the word I'm looking for, but I can't think of the right one at this time.

You should write a mini book on Japanese idioms :)
Good!
