⛩️ Japan Yakudoshi Checker (厄年)

In Japanese folk belief, certain ages are considered yakudoshi (厄年) - "calamity years" when a person is thought to be more prone to misfortune and should be extra careful. The custom is still widely observed: many Japanese people visit shrines at these ages, and family members may give protective amulets (お守り, omamori).

The unlucky ages differ by gender. For men the main years (本厄, hon-eki) are 25, 42, and 61. For women they are 19, 33, and 37. Around each hon-eki there are two supporting years: the year before is 前厄 (mae-eki, "pre-calamity") and the year after is 後厄 (ato-eki, "post-calamity"). Together they form a three-year "danger zone."

Note that 42 for men and 33 for women are considered the most severe (大厄, dai-yaku). The belief is cultural, not religious doctrine, and many people treat it lightly while still enjoying the shrine visits. It pairs naturally with the zodiac calculator and the rokuyō calendar when planning ceremonies.

The checker takes your birth year and gender, then works out your age in any reference year (default: the current year). For each hon-eki age it computes the calendar year: hon-eki year = birth year + age. The year before is mae-eki and the year after is ato-eki.

For example, a man born in 1990: his hon-eki years are 2015 (age 25), 2032 (age 42), and 2051 (age 61). His full danger zones are 2014–2016, 2031–2033, and 2050–2052. The tool highlights whichever of these matches the reference year you are checking.

You can change the reference year to check a past or future year - useful if you are planning a wedding, move, or business launch and want to know whether a family member is in a yakudoshi year. The result is purely traditional guidance, not a prediction. For life-event planning tied to age, also see our Shichi-Go-San tool.

1. Enter your birth year (e.g. 1990).
2. Select your gender (male or female).
3. Optionally set a reference year (defaults to the current year).
4. Click Check to see your 前厄, 本厄 and 後厄 years.
5. The year that matches your reference year is highlighted as "this year".

What are the yakudoshi ages for men?

Men's main unlucky ages (本厄) are 25, 42, and 61. Each is flanked by a 前厄 (year before) and 後厄 (year after), so the full danger zones are 24–26, 41–43, and 60–62.

What are the yakudoshi ages for women?

Women's main unlucky ages (本厄) are 19, 33, and 37, with 前厄/後厄 one year on each side (18–20, 32–34, 36–38). The 33rd year is considered the most severe for women.

Why is 42 considered the worst for men?

42 is the 大厄 (dai-yaku, "great calamity") for men - the single most feared yakudoshi age. Women's equivalent is 33. These are the ages most people mark with a shrine visit.

Is yakudoshi based on the Western age or the Japanese age?

Our tool uses the Western age (reference year minus birth year), which is standard for modern calculators. Traditional kazoe-doshi counting can shift the perceived age by one, so very traditional families may count slightly differently.

Should I be worried if I am in a yakudoshi year?

Yakudoshi is a cultural tradition, not a prediction. Many people treat it as a gentle reminder to be careful and to visit a shrine for peace of mind. It is not something to fear.

Can I check a future year?

Yes - change the reference year to any year you like. The tool will show which of your 厄年 zones (if any) falls in that year, which is handy for planning weddings or moves.

If you (or a relative) are in a yakudoshi year, the common custom is to visit a shrine early in the year - especially on or around 1 January - and receive an omamori (amulet) for protection, then return it the following year. The 42nd year for men and 33rd for women are the most celebrated, with many people making a special trip.

Remember that yakudoshi is counted by age, and in Japan age is often counted in the traditional "kazoe" style at New Year - but our tool uses the Western age (current year minus birth year), which is what most modern calculators use. If you want to be precise about a specific ceremony date, combine this with the rokuyō calendar to pick an auspicious day. And keep it light: plenty of people breeze through their yakudoshi years without a second thought.
