Yakudoshi are traditional Japanese unlucky ages — specific years of life regarded as calling for extra caution, when misfortune or illness is customarily thought more likely. It is a widely kept cultural custom, and many people mark a yakudoshi year with a protective blessing at a shrine or temple.

What are the yakudoshi ages for men and women?

In kazoedoshi counting, the main yakudoshi for men are 25, 42 and 61, and for women 19, 33, 37 and 61. The heaviest year, called taiyaku, is 42 for men and 33 for women. These ages are reckoned in the traditional counting system, not in Western age.

How is yakudoshi age counted?

Yakudoshi are counted in kazoedoshi, the traditional system in which you are one year old at birth and gain a year at New Year rather than on your birthday. That makes your kazoedoshi age usually about one more than your Western age, so the yakudoshi ages are checked in kazoedoshi.

What are maeyaku and atoyaku?

They are the years flanking a yakudoshi. Maeyaku is the year before, when the influence is felt to be gathering, and atoyaku is the year after, when it is felt to be fading. Because of them, a great year such as 42 for men is traditionally treated as a three-year span rather than a single year.

How do people protect against yakudoshi?

Many visit a shrine or temple for yakuyoke, also called yakubarai — a rite of warding off or purification asked for protection through the year, often folded into a New Year visit. The same tradition that names the unlucky year also provides this customary way of meeting it calmly.

Yakudoshi: the Japanese unlucky ages, explained

The traditional Japanese 'calamitous ages' — which years they are, how they are counted, and why they are custom, not a curse.

The short answer

Yakudoshi are the traditional Japanese calamitous ages: particular years of life long regarded as unlucky and calling for extra care. They are counted in kazoedoshi, the old system in which you are one year old at birth and gain a year every New Year rather than on your birthday, so your kazoedoshi age is usually about one more than your Western age. The main yakudoshi are 25, 42 and 61 for men and 19, 33, 37 and 61 for women, and many people mark them with a warding-off blessing at a shrine or temple. It is a living cultural custom, not a prediction that anything bad will happen.

What yakudoshi are

Yakudoshi — often translated as "calamitous years" or "unlucky ages" — are specific years in a person's life that Japanese tradition regards as needing extra caution. In these years, custom holds, misfortune, illness or upheaval are more likely, so people take more care and often seek a blessing.

It is a widely observed custom rather than a fringe superstition, kept up today by many who would not describe themselves as especially religious. Think of it less as a prophecy and more as a cultural marker: a handful of ages at which Japanese life traditionally pauses to take stock.

Counting in kazoedoshi

The ages are reckoned in kazoedoshi, the traditional East Asian way of counting age. In kazoedoshi you are already one year old at birth, and you gain a year at New Year rather than on your birthday.

The practical upshot is that your kazoedoshi age is usually about one more than your Western "満" age — sometimes two more, depending on where your birthday falls in the year. So when you check the yakudoshi ages below, you are checking them in kazoedoshi, not in the age you would give on a form.

The unlucky ages

The main yakudoshi differ for men and women, and each tradition centres on one especially heavy year. Ages here are in kazoedoshi.

	Main yakudoshi ages	Heaviest year (taiyaku)
Men	25, 42, 61	42 — a pun on shi-ni, meaning "to death"
Women	19, 33, 37, 61	33 — read as san-zan, "hard" or "terrible"

The main yakudoshi ages, in kazoedoshi, with the heaviest year of each.

The reason 42 and 33 loom largest is partly the wordplay. In Japanese, 42 can be read *shi-ni*, which sounds like "to death", and 33 can be read *san-zan*, meaning something wretched or terrible. The sound of the number is part of why the year carries weight.

Taiyaku, maeyaku and atoyaku

The heaviest year — 42 for men, 33 for women — is called the taiyaku, the great yaku. But the caution is not thought to switch on and off in a single year.

Each yakudoshi is flanked by two more: the maeyaku, the year before, when the influence is felt to be gathering, and the atoyaku, the year after, when it is felt to be fading. So a man's great year is traditionally treated as a three-year span around age 42, not a single twelve months.

Yakuyoke: warding it off

The custom comes with its own remedy, and this is the reassuring part. In a yakudoshi year, many people visit a shrine or temple for yakuyoke (or *yakubarai*) — a rite of warding off or purification, a blessing asked for protection through the year.

It is a calm, ordinary thing to do, often folded into the New Year visit, and it is exactly why yakudoshi need not be a source of dread: the tradition that names the unlucky year also hands you a customary way to meet it.
