正月ボケ
Meaning
New Year's brain fog — the sluggish, unfocused state people experience when returning to work or school after the holiday break.
A universally relatable condition in Japan where days of eating, drinking, sleeping, and watching TV during the New Year holiday leave people unable to concentrate when normal life resumes. It typically lasts the first week of January and is used as both a genuine complaint and a humorous excuse for poor performance. The term combines 正月 (New Year) with ボケ (daze/stupor), creating a vivid image of holiday-induced mental decline.
Examples
- 正月ボケがひどくてまだ仕事モードに入れない。 My New Year's brain fog is so bad I still can't get into work mode.
- 正月ボケでパスワード全部忘れた。 New Year's brain fog hit and I forgot all my passwords.
- 1月の最初の週はみんな正月ボケだから会議入れないで。 Don't schedule any meetings the first week of January — everyone's got New Year's brain fog.
