JLPT N1 Very formal / literary

〜tara saigo

Expresses that once a certain action happens, the situation changes irreversibly - usually in a negative way.

Formal, literary "once X happens, there's no going back (usually badly)" - near-synonym of n1-125's たが最後.

Formation

Explanation

The たら最後 grammar point indicates that once an action (in た-form) occurs, there is no going back and an unpleasant or unavoidable state follows. Often translated as 'once...then it's all over' or 'the moment...there’s no turning back.'
