Japanese Zodiac Eto: The Twelve Animals, Their Kanji and Hidden Uses

The core idea: twelve positions with animal nicknames

Picture a circle cut into twelve slices, like a clock face. Each slice is a sign with its own kanji: 子, 丑, 寅 and so on. Each year moves the pointer on by one slice, so after twelve years it is back where it started. The animals are usually explained as later nicknames that helped ordinary people remember the order. That is why the kanji of the signs are not the everyday kanji for the animals: the horse sign is 午, while the animal itself is 馬.

Read the diagram clockwise from the top: sign and reading inside, the everyday animal word outside, and the years 2020 to 2031 round the edge. To find any year's sign, count round from 2026, the horse at the bottom.

The twelve signs, their readings and the animal words

Six signs share their reading with the everyday animal word: ushi, tora, uma, hitsuji, saru and inu. The other six use a shorter or older reading. Ne is the sign, nezumi the rat; u the sign, usagi the rabbit; mi the sign, hebi the snake. Tori means bird, while the farmyard bird is niwatori, literally 'garden bird'. Tatsu is an old word for dragon, today usually ryū. And i is the old word for the wild boar itself: inoshishi is literally 'the i beast'.

To name a year, add toshi, which becomes doshi: uma-doshi, written 午年 or うま年. For the short signs both forms are heard: u-doshi or usagi-doshi, i-doshi or inoshishi-doshi. For earlier birth years, subtract twelve.

Confusable pairs: the boar and the pig, 午 and 牛

The twelfth sign is where Japan parts company with the Chinese zodiac. In China the sign 亥 is the pig; in Japan it is the inoshishi, the wild boar. The kanji 猪 adds to the confusion: in Chinese it means pig, in Japanese wild boar. The farm pig is buta, 豚. So a Chinese friend born in a pig year is, in Japanese terms, i-doshi.

The second pair catches readers of kanji. 午, the horse sign, and 牛, cow, differ by one stroke: in 牛 the vertical line pokes through the top. A third pair is 未, the sheep sign, and 末, end: in 未 the upper line is the shorter one. 未 on its own means not yet, as in miseinen, 未成年, literally 'not yet of age', a minor.

Your sign: asking about age, toshi-otoko and toshi-onna

Asking an adult's age outright can feel blunt, and the zodiac offers a softer route. A colleague may ask nani-doshi desu ka, literally 'which year are you?'. Your answer places you in a twelve-year cycle, and the listener's eyes do the rest. People also offer their sign to hint at their age without stating it.

Two words come with this. Hitomawari, literally 'one lap', means an age gap of twelve years. Toshi-otoko and toshi-onna, year man and year woman, are people whose sign matches the current year: in 2026, everyone born in 1966, 1978, 1990, 2002 and 2014, turning 60, 48, 36, 24 and 12. It is considered a lucky year, and shrines and temples often invite them to throw the beans at setsubun in February.

The zodiac at New Year: cards, stamps and ornaments

From late autumn the coming year's animal is everywhere: on New Year cards and stamps, on ema, the wooden wish plaques sold at shrines, and as small ornaments, eto no okimono, in the entrance hall. Cards written in December 2026 greet 2027, so they carry hitsuji, the sheep. Writing the cards themselves is covered in a separate guide on nengajō.

One subtlety: in almanacs and fortune-telling the zodiac year starts at risshun, the old start of spring, 4 February in 2026, so a fortune-teller may place a mid-January birthday under the previous sign. In conversation and on cards, everyone uses the calendar year. The zodiac is also separate from era names: Reiwa 8 and uma-doshi both name 2026, but era years restart with each emperor, while the signs roll on regardless.

At home in December, a family is getting ready for the coming year.

Beyond the basics: the circle as a clock and a compass

Before Western clock hours, the same twelve signs divided the day into two-hour blocks. Ne no koku, the hour of the rat, ran from about 11 p.m. to 1 a.m., which puts the rat at midnight and the horse at noon. Three everyday words come from this, using go, the on'yomi of 午. Gozen, 午前, a.m., is literally 'before the horse'; gogo, 午後, p.m., 'after the horse'; and shōgo, 正午, noon, 'exactly the horse'.

The circle also worked as a compass, with ne at north, u at east, uma at south and tori at west. A meridian is still shigosen, 子午線, the 'rat-horse line'. The north-east, between ushi and tora, is the kimon, 'demon gate', of traditional geomancy. Ushimitsu-doki, the ghost hour around 2 a.m., is literally the third part of the hour of the ox.

Beyond the basics: ten stems, sixty years and hinoe-uma

Strictly, eto (干支) is literally 'stem and branch': the twelve signs are the branches, each paired with one of ten stems, jikkan (十干), such as kinoe, 甲, and hinoe, 丙. Ten and twelve line up again only after sixty steps, so every year has one of sixty names, and your full eto returns only at sixty. That return is kanreki, the sixtieth birthday.

A few of the sixty are famous. Kōshien Stadium opened in 1924, a kinoe-ne year, 甲子, the first of the sixty, and was named after it. And 2026 is hinoe-uma, fire and horse, which an old superstition linked to fires and headstrong women. In 1966, the last hinoe-uma year, births in Japan fell by about a quarter compared with 1965, then bounced back. Days carry signs too, which is why eel is eaten on doyō no ushi no hi, the day of the ox in late July.

Common mistakes with the Japanese zodiac

Calling the twelfth animal buta. The cause is the Chinese zodiac, which many learners meet first, and the kanji 猪, pig in Chinese. In Japan the sign is the wild boar: inoshishi-doshi or i-doshi.

Mishearing 何年生まれですか. The cause is that nannen, which year, and nani-doshi, which sign, share the same kanji. Nannen umare asks for a calendar year such as 1990, nani-doshi umare for a sign. If unsure, answer both.

Writing 馬年 or 牛年 on a card. The cause is looking up the animal's kanji instead of the sign's. Year names use the sign kanji, 午年 and 丑年, and hiragana, うま年, is always safe.

Putting this year's animal on next year's card. The cause is seeing the horse all year; December cards greet the coming year, so they need the sheep.
