noun
the year after an unlucky year
Refers to the year following a person's 厄年 (yakudoshi, 'unlucky year') in the traditional Japanese age reckoning. It is considered a year when one should still be cautious, though less dangerous than the main unlucky year. Often used in the context of shrine visits and protective rituals.
