In Japan, yakudoshi are ages traditionally believed to bring misfortune, and shrines ask your age "the counted way." The confusion is that yakudoshi are reckoned in kazoedoshi (counted age), not your actual age. Below we explain how kazoedoshi works and give tables — computed with our Yakudoshi calculator — of the birth years in their main unlucky year in 2026. Yakudoshi is an old custom with no scientific basis.
Three years: maeyaku, hon'yaku, atoyaku
A yakudoshi is an age said to be prone to calamity. The central year is the hon'yaku (main year); the years just before and after are the maeyaku (pre-year) and atoyaku (post-year). So a yakudoshi is not a single year but usually a three-year stretch: maeyaku → hon'yaku → atoyaku.
How kazoedoshi works, and why it differs from actual age
In kazoedoshi, you are 1 the moment you are born — the year of birth already counts as age 1. After that you add a year not on your birthday but every New Year's Day (January 1). Because the increment lands on New Year rather than your birthday, the gap from your actual age depends on the time of year:
- Before your birthday this year: kazoedoshi = actual age + 2
- After your birthday this year: kazoedoshi = actual age + 1
Because yakudoshi are stated in kazoedoshi, the "I'm only 40 but already in my main year" feeling comes from this +2 / +1 offset. Shichi-Go-San, Japan's rite for children aged 3, 5 and 7, uses the same counted-age system.
Yakudoshi by gender, and the "great" years
The unlucky kazoedoshi ages differ by gender:
- Men: 25, 42, 61
- Women: 19, 33, 37, 61
Among these, 42 for men and 33 for women are the taiyaku (great yakudoshi), considered the heaviest. The common explanation is a pun: 42 reads shi-ni ("to death"), and 33 evokes sanzan ("miserable"). These are folk sayings, nothing more.
Birth years in their hon'yaku in 2026 (tables)
From the definition of kazoedoshi, the birth years (Gregorian) whose main year falls in 2026 are:
Men
| Yakudoshi (kazoedoshi) | Birth year |
|---|---|
| 25 | 2002 |
| 42 (taiyaku) | 1985 |
| 61 | 1966 |
Women
| Yakudoshi (kazoedoshi) | Birth year |
|---|---|
| 19 | 2008 |
| 33 (taiyaku) | 1994 |
| 37 | 1990 |
| 61 | 1966 |
The great years are customarily watched over all three years. As of 2026, the maeyaku / hon'yaku / atoyaku of each taiyaku fall on these birth years:
| Group | Maeyaku | Hon'yaku | Atoyaku |
|---|---|---|---|
| Men · taiyaku 42 | count 41 born 1986 | count 42 born 1985 | count 43 born 1984 |
| Women · taiyaku 33 | count 32 born 1995 | count 33 born 1994 | count 34 born 1993 |
When to get a yakubarai (regional variation)
Yakubarai — the purification ritual to ward off misfortune — is often received between New Year's Day and Setsubun (the day before the start of spring) or during the New Year period, but the timing varies by region and by shrine or temple. Some people go on their birthday or whenever they feel moved to. When to go is best treated as a matter of custom, not a fixed rule.

How does kazoedoshi work for people born early in the year?
Is yakubarai only for the hon'yaku year?
The tables were computed from the definition of kazoedoshi (born = age 1, +1 each New Year's Day) with our Yakudoshi calculator (as of 2026). Yakudoshi is an old custom with no scientific basis. As of 2026-07-16.
