na-adjective, noun
unwise plan; bad policy; inexpedient
Used to describe a course of action, decision, or policy that is not advisable or likely to backfire. Often appears in formal or written contexts.

I think that proposal is unwise.
今、値上げするのは不得策だ。
Raising prices now would be a bad move.
Reckless, without forethought. 不得策 is more about poor judgment or inexpediency, not necessarily recklessness.
