Year of the Fire Horse 2026: The Superstition That Cut Japan's Births by 25%

By Data Saju · Published October 7, 2026

In 1966, the last Year of the Fire Horse (丙午, Bing Wu), births in Japan dropped from 1,823,697 to 1,360,974 — down 25.4% — because of a belief that Fire Horse girls grow up too headstrong. 2026 is a Fire Horse year again. Our almanac engine built all 4,368 charts that can be born in it: 70.9% carry three or more Fire characters, 5.0 times the usual 14.3%. But the Day Master — the character that stands for your temperament — is Fire for just 19.8%, the same as any other year.

What happened in Japan in 1966?

Births fell by about 463,000 in a single year, then rebounded above the old level in 1967. No war or recession caused it — couples simply avoided or postponed having a child that year. Demographers still cite it as a rare case of a superstition visibly bending a nation's birth curve. (Sources: Japan Ministry of Health, Labour and Welfare vital statistics; Our World in Data.)

Why was the Fire Horse feared?

Bing Wu pairs the stem 丙 (yang Fire, the Sun) with the branch 午 (the Horse, midsummer Fire). Both characters are Fire, so among the sixty pillars it is the most fiery. In Japan the fear grew from an Edo-period tale about Yaoya Oshichi, a girl said to be born in a Fire Horse year who set a fire for love. It hardened into the idea that Fire Horse women are hot-tempered and shorten their husbands' lives.

The effect had appeared before: in the 1906 Fire Horse year, Japanese births fell 4% (girls 6.8%), though much of that came from parents registering daughters' births in the neighboring years (Tottori Prefectural Archives).

Korea's version: the 1990 White Horse

In Korea the feared year was the White Horse (庚午, Metal Horse) rather than the Fire Horse. In 1990, a White Horse year, Korea recorded 116.5 boys born for every 100 girls — the most skewed birth sex ratio since records began in 1970 (349,617 boys and 300,121 girls). Researchers read it as a strong son preference made worse by the superstition (National Archives of Korea; Statistics Korea vital statistics). The next White Horse year is 2050.

We counted the charts: is a Fire Horse baby really "fiery"?

For each year from 2016 to 2026 (from the day after Lichun to the day before the next Lichun), we built every chart born on every day at each of the twelve two-hour periods — 4,368 charts a year — and counted the five elements in the eight characters.

Because both characters of the year pillar are Fire, a Fire Horse chart holds 3.07 Fire characters on average, against 1.41 in other years, and Fire is the single strongest element in 53.8% of charts (other years: 9.9%). Years with Fire on only one side — Fire Monkey, Fire Rooster, Wood Snake — come out high too, but only the Fire Horse has it on both.

Yet saju reads temperament from the Day Master — the stem of your birth day — not from the year. The Day Master changes daily regardless of the year, so in 2026 it is Fire (丙 or 丁) for 19.8% of charts, essentially the same as other years (20%). The year pillar is two of eight characters, and a chart is read as a balance of year, month, day and hour. Even by saju's own rules, "Fire Horse girls are headstrong" doesn't hold up.

How saju reads a Fire-heavy chart

• Strengths: Fire is expression, warmth, drive and visibility — people who move fast and shine in front of others.
• Balance: too much Fire can flare and burn out, so Water and Earth are valued to cool and hold it. Which element helps is a person's useful element, and it differs from chart to chart.
• Nothing about gender: no rule in saju says Fire is worse in a woman's chart. That belief is old social prejudice, not chart reading.

When does the Fire Horse year start and end?

In saju and BaZi the year turns at Lichun, the Start of Spring — not on January 1, and not on Lunar New Year. Our engine puts the 2026 Fire Horse year from February 3, 2026 at 3:02 PM to February 3, 2027 at 8:46 PM (US Eastern time). Chinese New Year 2026 fell later, on February 17, which is why zodiac sites disagree about early-February birthdays.

There's an irony in 1966, too: Japan's superstition followed the calendar year. By saju's Lichun rule, a baby born from January 1 to February 4, 1966 was actually a Wood Snake, and one born from January 1 to February 4, 1967 was the real Fire Horse.

Will births drop again in 2026?

Japanese population researchers think a 1966-sized drop is unlikely: births are already far lower and far fewer people hold the belief (Institute for Social Vision Design). The real answer will come with the official 2026 statistics.

Frequently asked questions

Are women born in a Fire Horse year really headstrong? Not even by saju's rules. A Fire Horse chart has extra Fire in the year pillar, but the Day Master — the core of temperament — is Fire for 19.8% of people, the same as any year, and nothing in saju treats Fire differently by gender.

Is 2026 a bad year to have a baby? No. Saju reads every chart as a balance of eight characters and doesn't sort birth years into good and bad.

When does the 2026 Fire Horse year begin in BaZi? At Lichun, February 3, 2026 at 3:02 PM (US Eastern), and it runs until Lichun on February 3, 2027 at 8:46 PM.

When is the next Fire Horse year? Every sixty years: the last ones were 1846, 1906, 1966, and the next is 2086.

What's the difference between a Fire Horse and a White Horse? Both are Horse years (午). With the stem 丙 (Fire) it is the Fire Horse; with 庚 (Metal, white) it is the White (Metal) Horse.

Birth figures come from official Japanese and Korean statistics as cited. The chart counts were calculated by our almanac engine: 48,084 charts across 2016–2026, at the middle of each two-hour period, leaving out the Lichun days themselves.
