What Is Jūnishi? Understanding the Japanese Zodiac
Share
If you have ever seen a Rat, Ox, Tiger, Dragon, or Rabbit associated with a Japanese New Year celebration, you have encountered Jūnishi (十二支), the traditional Japanese zodiac.
Jūnishi is a system based on a repeating cycle of twelve animals. Each year is represented by a different animal, and after twelve years, the cycle begins again.
The tradition is deeply connected with Japanese culture, calendars, New Year celebrations, folklore, and everyday symbolism. It is also one of the most recognisable examples of how animals have been used to represent time and tradition in Japan.
But where did Jūnishi come from? Why are there twelve animals? And why these particular animals?
Let's take a closer look.
What Does Jūnishi Mean?
The Japanese word Jūnishi (十二支) literally refers to the twelve signs or twelve branches.
The system originated from the older Earthly Branches, a traditional East Asian system used to organise time. The twelve branches were eventually associated with animals, creating the twelve-animal zodiac that became familiar across East Asia.
Japan adopted this system centuries ago, and the twelve animals became incorporated into Japanese culture and calendar traditions.
The twelve animals are:
Rat (子, Nezumi)
Ox (丑, Ushi)
Tiger (寅, Tora)
Rabbit (卯, Usagi)
Dragon (辰, Tatsu)
Snake (巳, Hebi)
Horse (午, Uma)
Goat (未, Hitsuji)
Monkey (申, Saru)
Rooster (酉, Tori)
Dog (戌, Inu)
Boar (亥, I)
Once the twelfth animal has passed, the cycle returns to the Rat.
Why Are There 12 Animals?
The number twelve comes from the original twelve-part system of the Earthly Branches.
The twelve branches were used as a way of organising time, including years, months, days, and even divisions of the day. Animals were later assigned to these twelve positions, giving the system the familiar form of a twelve-animal cycle.
The result is a pattern that repeats every twelve years.
For example:
2024 → Dragon
2025 → Snake
2026 → Horse
2027 → Goat
2028 → Monkey
After 2031, the cycle begins again with the Rat in 2032.
This repeating structure is one of the simplest ways to understand Jūnishi: one animal represents each year, and twelve animals make one complete cycle.
The Famous Story of the 12 Animals
There is a much more entertaining explanation for the order of the animals.
According to a popular traditional story, a great race was organised to determine which animals would receive a place in the zodiac and in what order.
The animals were told to cross a river and reach the finish line. The first twelve to arrive would earn a position in the zodiac.
The Rat knew that it would struggle to compete physically with some of the larger animals, so it used its intelligence.
The Ox was strong and steady, and the Rat asked to travel with it. The Ox agreed and carried the Rat across the river.
Just before they reached the finish line, the Rat jumped off the Ox and crossed first.
The Ox arrived second.
The remaining animals followed, creating the order we know today:
Rat → Ox → Tiger → Rabbit → Dragon → Snake → Horse → Goat → Monkey → Rooster → Dog → Boar
There are different versions of the story, with details changing between cultures and retellings. It is best understood as a folk story rather than the historical origin of Jūnishi.
Still, it is a wonderfully memorable way of explaining why the zodiac begins with the Rat rather than the larger and more powerful animals.
The 12 Animals of Jūnishi
The complete cycle contains twelve animals, each occupying a specific position.
1. Rat | 子
Nezumi (ねずみ)
The Rat begins the Jūnishi cycle.
2. Ox | 丑
Ushi (うし)
The Ox follows the Rat as the second animal.

Tora (とら)
The Tiger is the third animal.
4. Rabbit | 卯
Usagi (うさぎ)
The Rabbit occupies the fourth position.
5. Dragon | 辰
Tatsu (たつ)
The Dragon is the fifth animal and the only mythical creature in the cycle.
6. Snake | 巳
Hebi (へび)
The Snake is the sixth animal.
7. Horse | 午
Uma (うま)
The Horse takes the seventh position.
8. Goat | 未
Hitsuji (ひつじ)
The Goat is the eighth animal. You may also see this animal described as a Sheep in English translations.
9. Monkey | 申
Saru (さる)
The Monkey is the ninth animal.
10. Rooster | 酉
Tori (とり)
The Rooster occupies the tenth position.
11. Dog | 戌

After the Boar, the cycle returns to the Rat.
Jūnishi and the Japanese New Year
One of the best times to see Jūnishi in Japan is around Shōgatsu (正月), the Japanese New Year.
Each year has its own zodiac animal, so the animal associated with the new year often appears throughout seasonal celebrations and visual culture.
You might see the year's animal represented on:
New Year's greeting cards
Decorations
Illustrations
Stationery
Gifts
Advertisements
Packaging
Traditional artwork
Seasonal merchandise
The zodiac animal becomes something of a visual symbol for the year.
This is one reason Jūnishi continues to feel relevant in modern Japan. It is not simply something found in historical texts. The animals continue to appear in contemporary design and everyday New Year traditions.
Is Jūnishi the Same as a Horoscope?
Not exactly.
Jūnishi is often casually referred to as the Japanese zodiac or even the Japanese horoscope, but the system itself is primarily a twelve-year calendar cycle.
Your Jūnishi animal is generally determined by your birth year.
For example, someone born in 2026 is associated with the Horse, while someone born in 2027 is associated with the Goat.
The animals can also have traditional associations and cultural symbolism, but that is a separate part of the subject.
If you are interested in what those animals traditionally represent, that is a much deeper question in its own right.
Why Does Jūnishi Still Matter?
Traditions survive when they remain meaningful enough to be carried into new generations.
Jūnishi has done exactly that.
The twelve animals provide a simple way to connect a particular year with a recognisable symbol. At the same time, the tradition connects modern Japan with older systems of timekeeping, folklore, language, and cultural history.
It is also visually adaptable.
The animals can appear in traditional paintings, modern illustrations, graphic design, decorations, clothing, and contemporary artwork without losing their connection to the original tradition.
That combination of history, symbolism, and visual identity is part of what makes Jūnishi so fascinating.
Jūnishi as Inspiration
The twelve animals offer twelve distinct visual subjects, each with its own shape, character, and cultural history.
That makes the Jūnishi particularly interesting from a design perspective.
Astré explores this idea through its Jūnishi collection, interpreting the twelve animals through a contemporary Japanese-inspired fashion approach while keeping the structure of the traditional zodiac at the centre of the collection.
Each piece represents one position in the twelve-animal cycle, creating a complete series rather than twelve unrelated designs.
A Tradition That Repeats
At its simplest, Jūnishi is a twelve-year cycle.
But behind that simple structure is a much longer history of calendars, folklore, language, New Year traditions, and cultural symbolism.
The Rat begins the cycle.
The Ox follows.
Then come the Tiger, Rabbit, Dragon, Snake, Horse, Goat, Monkey, Rooster, Dog, and Boar.
And after the Boar, everything begins again.
That repeating cycle is perhaps the most fitting part of Jūnishi. Every year brings a new animal, while the tradition itself continues from one generation to the next.
