~まい
~mai
will surely not; let's not
When to use it
Use ~まい in formal writing and stiff speech as the literary equivalent of ~ないだろう (strong negative conjecture) or ~ないつもりだ/~ないようにしよう (negative volition). In business contexts it appears in written reports, formal correspondence and set expressions like ~ではあるまいか ("could it not be that…") and ~(よ)うが~まいが ("whether or not"). It sounds archaic and decisive in conversation, so reserve it for documents, editorials, or a deliberately weighty spoken remark.
Formation

This quarter's profit drop isn't due to the weak yen alone.
