洞ヶ峠を決め込むほらがとうげをきめこむ

expression, godan verb (-mu)

wait and see which way the wind blows; sit on the fence; wait for a good opportunity

Proverbial expression originating from a historical anecdote about a warlord who waited at Horagatoge to see which side would win before joining. Used when someone delays a decision to see how a situation develops, often with a negative connotation of opportunism.

• 彼かれは洞ヶ峠ほらがとうげを決きめ込こんで、どちらの案あんにも賛さん成せいしなかった。

  He sat on the fence and didn't agree with either proposal.

• 選せん挙きょの結けっ果かが出でるまで洞ヶ峠ほらがとうげを決きめ込こむつもりだ。

  I plan to wait and see until the election results come out.
