Shinto does not have a single, unified family tree like the Greek or Norse pantheons, but the Kojiki (712 CE) and Nihon Shoki (720 CE) present a core genealogical line: the primordial creator kami gave birth to the islands of Japan and then to Amaterasu (sun goddess), Tsukuyomi (moon god), and Susanoo (storm god), from whom the imperial line descends. Beyond this central lineage, hundreds of local kami are connected through regional myths, clan traditions, and later compilations, so any family tree is a patchwork of overlapping accounts rather than a single canonical chart.
Background: Where the Kami Genealogies Come From
The primary sources for Shinto divine genealogy are the two earliest Japanese chronicles. The Kojiki (“Records of Ancient Matters”) was compiled in 712 CE by Ō no Yasumaro under imperial order, and the Nihon Shoki (“Chronicles of Japan”) followed in 720 CE. Both blend mythology, legend, and early history to legitimize the imperial family’s descent from the sun goddess Amaterasu. They were written after Buddhism and Chinese writing had arrived in Japan, so the myths were recorded in Chinese-style court language, but they preserve older oral traditions from the Yamato court and various clans.
Because these texts were political documents, they sometimes disagree. For example, the Kojiki says Izanagi and Izanami created the islands of Japan, while the Nihon Shoki offers several variant accounts of the same event. Later sources, such as the Kogo Shūi (807 CE) and the Engishiki (927 CE), add more kami names and local traditions. Shinto has no equivalent of a single holy book, so genealogical details vary by region, shrine, and historical period.
The Central Lineage: From Nothingness to the Sun Goddess
The Kojiki begins with the appearance of five primordial kami (the Kotoamatsukami) who emerged in the high plain of heaven. They were followed by the “Seven Generations of the Age of the Gods,” a series of kami pairs, culminating in the creator pair Izanagi and Izanami. Their story forms the trunk of the family tree:
- Izanagi and Izanami were brother and sister who churned the primordial sea with a jeweled spear to create the first island, Onogoro. They then gave birth to the islands of Japan and numerous kami of natural phenomena.
- Izanami died giving birth to the fire god Kagutsuchi, and descended to the underworld (Yomi). Izanagi followed her but fled when he saw her rotting corpse, and upon returning to the surface he purified himself with a ritual bath.
- From his left eye was born Amaterasu (sun goddess), from his right eye Tsukuyomi (moon god), and from his nose Susanoo (storm god). This triple birth is the most famous episode in the Kojiki.
- Amaterasu’s grandson Ninigi was sent down to rule the Japanese islands, and his great-grandson Emperor Jimmu became the first human emperor of Japan, according to tradition.
This lineage is the basis for the imperial family’s claim to divine descent, and it is still recited in court rituals. However, the Nihon Shoki gives alternative versions of Izanagi’s children, sometimes making Tsukuyomi the elder or adding a fourth child, so the exact order is not fixed.
How the Family Tree Works: Key Relationships and Roles
Shinto kami are not omnipotent gods in the Western sense; they are spirits or deities associated with natural forces, ancestors, and places. Their genealogies often reflect their functions:
- Amaterasu is the sun goddess and the most important kami in the imperial cult. Her main shrine is Ise Grand Shrine, and she is considered the ancestor of the imperial line.
- Tsukuyomi is the moon god. In one myth, he killed the food goddess Uke Mochi, which caused Amaterasu to separate from him, explaining why day and night are apart.
- Susanoo is the storm god, but he is also a culture hero who slayed the eight-headed serpent Yamata no Orochi and rescued the princess Kushinada-hime. He is the ancestor of the Izumo clan, a rival to the Yamato court.
- Ōkuninushi (also called Ōnamuchi) is Susanoo’s son or descendant, depending on the text. He ruled the land of Izumo and later yielded it to the heavenly gods, a myth that explains the transfer of power from local deities to the imperial line.
- Inari, the rice and fertility kami, is often depicted as a family of three deities, but their genealogy is not tied to the central line.
Many shrines have their own engi (founding legends) that connect their local kami to the main pantheon, but these are often later inventions to gain prestige.
Common Problems and Misconceptions
One common misconception is that Shinto has a single “family tree” like the Greek gods. In reality, the Kojiki and Nihon Shoki record dozens of kami who are not related to each other, and many local kami have no genealogical connection at all. Another problem is that the texts contradict each other: for example, the Nihon Shoki says that Izanagi and Izanami were the seventh generation of gods, while the Kojiki says they were the seventh pair but counts differently. Also, the gender of some kami changes between texts—for example, the war god Hachiman is sometimes a deified emperor, not a primordial deity.
Another issue is that the imperial lineage was deliberately constructed to unify Japan under one rule, so the myths are not purely religious but also political. This is why the family tree is so prominent in the chronicles, but it does not cover the thousands of kami worshipped at local shrines.
How to Trace a Kami’s Lineage
If you want to find out where a particular kami fits in the family tree, you need to check multiple sources:
- Look up the kami in the Kojiki and Nihon Shoki indexes—many online editions have searchable names.
- Check the Engishiki, which lists shrine names and some kami but rarely gives genealogies.
- Consult shrine-specific engi (legends) or local histories, which often provide alternative parentage.
- Be aware that some kami are amalgamations of earlier deities, so their lineage may be a later invention.
For example, the god Tenjin is a deified historical figure, Sugawara no Michizane (845–903 CE), not a primordial kami, so he has no place in the ancient family tree. Similarly, Hachiman is a syncretic god who is both a Shinto kami and a Buddhist bodhisattva, and his ancestry is debated.
Comparisons with Other Pantheons
Unlike Greek or Norse mythology, Shinto does not have a creation story that explains the entire universe. The Kojiki begins with the formation of the Japanese islands, not the cosmos, and the kami are not organized into a single ruling family. In Greek myth, Zeus is the king of the gods, but in Shinto, Amaterasu is the most revered, yet she does not rule over other kami—she is the ancestor of the imperial clan, but many kami act independently. Also, Shinto kami are not immortal in the same way; they can die, be killed, or fade away, as seen in the myth of Izanami’s death.
The genealogical structure is also more fluid: a kami can have multiple parents in different texts, and some are born from objects or actions (like the kami born from Izanagi’s clothing when he threw them down). This makes a single family tree impossible to draw accurately.
Safety and Accuracy: Reading the Myths Responsibly
When studying Shinto genealogy, it is important to remember that these are religious texts of a living tradition. They should be described with respect, not dismissed as “fiction.” Also, because the Kojiki and Nihon Shoki were written to support imperial rule, they do not represent the beliefs of all Japanese people, especially those from regions like Izumo, which had its own mythology. Always check the original text or a scholarly translation, and avoid relying on modern retellings that may simplify or alter the relationships.
Frequently Asked Questions
Who is the highest god in Shinto?
There is no single supreme god. Amaterasu is often considered the most important due to her connection to the imperial line, but she is not an all-powerful creator. The primordial kami like Ame-no-Minakanushi (the “Lord of the August Center of Heaven”) are older but rarely worshipped.
Is the Japanese emperor really a descendant of the sun goddess?
According to the Kojiki and Nihon Shoki, the imperial line descends from Amaterasu through her grandson Ninigi. This was the official doctrine until 1946, when Emperor Hirohito renounced the claim of divinity, but the genealogy is still part of the imperial rituals.
Why are there so many different versions of the same myth?
Because the Kojiki and Nihon Shoki were compiled from different oral traditions and for different political purposes. The Nihon Shoki includes multiple variants of the same story, which suggests that the compilers were trying to preserve all known versions rather than pick one.
Are there any female kami in the main line?
Yes, Izanami is a creator goddess, and Amaterasu is female. Other important female kami include the food goddess Uke Mochi and the sake goddess Omiwa. However, the imperial line is traced through male descendants, so the family tree is patrilineal.
Do Shinto gods have children like in Greek myths?
Some do, but many kami are not depicted as having offspring. The genealogies in the chronicles focus on the imperial line and a few major clans, so most kami are childless. For example, Susanoo has children, but Tsukuyomi does not appear in any genealogy.
