Juraian Royal Families

The family tree of Juraian Royal Houses and those living in Jurai.

Foundation of Jurai

It is unclear whether the First Emperor was a Masaki and the other houses were contemporaries or if the four houses split from his descendants. But is clear that the history of Jurai was made of a mix of the houses.

Masaki Village

"The Masaki Ladies Assembly" apparently seated roughly by age. OVA 4

Masaki Village is made of Katsuhito Masaki / Yosho and those directly descended from him. For most of the Family there is not a detailed family tree, but generations can discerned.

Direct 4rd Generation: Mizune Masaki is the great-granddaughter of Katsuhito and Kasumi. Considering the longevity of even the Earth Masakis, she could have been born at most any point between the 15th through the 17th century.

Other current Masaki Villagers seem to be less direct than Mizune and from later generations.

"The Masaki Men's Group."

Akie Masaki serves as the village elder.

Kei Masaki treats Akie as an elder sister. There are two other Masaki women who seem to be her friends and contemporaries

Kiyone was born approximately in the mid-18th century.

Otoka, Fuka, and Nobuyuki seem to be around the same age, all having grown up in the 19th century.

The majority of the unnamed "Masaki Ladies Assembly" that met before Nobuyuki and Rea's wedding seem to from this generation or younger. That would definitely be the case if they were seated by age and generation.

Tennyo and Hakuryo are dating and seem to be around the same age.

Tsukiko seems to be the age that she appears, having had her children at the beginning of her Galaxy Police career.

Kasumi, mother of Taro, seems to to be the youngest of the adult women. Her husband is a pure-blooded Earthling and not allowed to be informed of her alien heritage at this time.

Kiriko, Tenchi, Kai, and Taro are seemingly the youngest in Masaki Village. It seems that, with so many unnamed Masaki women, there could definitely be more, but Tenchi's childhood is described as one with few children around his age

Seina Yamada is the youngest male member to be added to the Earth Masaki Family, Royal Juraian Family, and the Men Assembly on Earth after marrying Kiriko.

Planet Seniwa Families(F)

The Seniwa Empire's government is a mix of Oligarchy and Representative Democracy. The Seniwa Council represents the various planets and regions of the empire but the Executive branch has been dominated by the Kuramitsu family for thousands of years. The family are the only residents of the planet of Seniwa but they are not strictly a monarchy. The immediate family of the ruler is favored to be the next ruler but can also be chosen by the merit of the most accomplished family member.

Unknown Kuramitsu
Misaka Kuramitsu
Washu HakubiG
Miyuki's Father
Minami's Wife
Mashisu Makibi B

*step-siblings who married
** took Kurumitsu name, previous surname unknown.

The Choushin(G)

In the beginning, the Chousin created the multiverse.


Washu Hakubi

The "Family Tree" of Washu Hakubi, Washu-Kami while descended to the Third Dimension.

At this point, Mikumo is the only traditionally born offspring of Washu. All of his descendants, as listed in the Seniwa section, could also be included here. The rest here are a combination of clones, creations, and birth through means of combination through Masu.

Most likely, Tenchi's future son, who marries a revived Masaki in the future, is probably Washu's natural offspring as well, but it is uncertain at this time.

Naja Akara

*an alien "mass" that Washu uses at the other half in her "created" children.
**A clone of Naja Akara, as created by Washu. Presumably also formed out of a proto-Ryoko.
**Kagato was originally a hermaphrodite who hated his female half and separated "her" from him and tried to kill her. This half was eventually became/merged with Noike. The broken line is intentional, to signify the unnatural relationship.


It would be impractical to attempt a normal family tree. This chart is replicated from the Royal Tree page.

You could almost inlude Kyoko and Honoka on Washu's tree as well, but they are more like partial "creations" made from Masu. Unlike Ryoko, Ryo-Ohki, and Fuku, they do not include any of Washu's genetic material.

Here is a list of known tree-ships, their generation, and their partners.

Royal Tree Name Generation Partner Notes
Tsunami 0
Sasami Masaki Technically, Sasami and Tsunami are the same.
Kirito 1st Azusa Masaki Initially unofficially partnered with Mitsuki, presumably being one of the five 1st-gen trees that kept her alive. She was then apparently assimilated by Kirito. Kirito means "Sealing Fog."
Funaho 1st Yosho Masaki The only known rooted tree not to lose its power.
1st Seina Yamada Jinbu/ Zinv greatly predates the actual founding of Jurai, being one of a few seeds Tsunami gave to a long dead civilization. Seina tends to call his 1st-gen Mecha/ship Zinv, the name D introduced it as. In Tenchi Muyo! Ryo-Ohki 4th OVA Episode 4, it is confirmed that the name of the seed itself is named Jinbu. It has also been known as "Idol." In the Renza Federation, many call it "The Original."
Karin 2nd Misaki Masaki Karin means "Hazy Scales" and is also a Juraian term for a certain type of cloud formation. It is a twin of Mizuho.
Mizuho 2nd Funaho Masaki Mizuho means "Water Crest." More information about this tree below. It is a twin of Karin.
Ryu-Oh 2nd Ayeka Masaki Regenerated after being killed by Kagato.
Mikagami 2nd Seto Kamiki Seto, as a non-native Juraian proves beyond a doubt that one does not have to be a native Juraian in order to be partnered with a royal tree. Mikagami means "Water Reflection."
Mizuki 2nd Kiriko Masaki While this was done for purely political moves on the part of Lady Seto and Jurai (for their protection), the fact that the royal trees went along with it says something IMO.
unknown 2nd Kotono Tatsuki Unknown details.
unknown 2nd Katsuki Amaki Shuzan Amaki's son, the Head of House Amakil after Shuzan gave up the position.
Kyouko 3rd Noike Kamiki This is a secret experimental ship designed to give 3rd-gen tree-ships the power of a 2nd-gen tree-ship.
Mizunagi 3rd Tatsuki Nishia
Nishia and Mizunagi aided and protected Wahu when she traveled from the planet Kanemitsu to the Juraian Imperial Academy. This may also be one of the ships that took part in the battle against Ryoko and Ryo-ohki.
unknown 3rd Utsutsumi Kamiki This is Seto-sama's husband.
unknown 3rd Shuzan Amaki Shuuzan is the current head of House Amaki and a big schemer.
unknown 3rd Tatsua Masaki In the absence of the Royal Family, Tatsua, commander of the planetary defense fleet, led the charge against Ryoko during her attack on Jurai. His tree and the others had trouble attacking Ryo-Ohki because its power came from the same sort of power as the trees and the trees were made to subjugate to any tree greater than their own. This ship was downed by Ryo-Ohki when he tried to make it collide with it, but Ryo-Ohki commanded it to drop its Light Hawk Wings and it shot it down with a direct hit. It is unknown if the tree survived.
unknown unknown Minaho Masaki Series creator, Masaki Kajishima revealed in an interview that Minaho, Yosho and Airi's daughter, is partnered with a Royal Tree. However, the name and generation of that tree has not been revealed as far as we know.
unknown unknown Amame Masaki Though she is now Yotsuga Amame, she was once a member of House Masaki and the mother of Azusa. Amane left Jurai, and abdicated her position in House Masaki, by planting her tree in the soil.
unknown unknown 1st Emperor of Jurai In the English-speaking world, we don't know if there is any information about his Royal tree partner. It is believed that he would have been partnered with a 1st-gen tree since Tsunami made the pact with him.
unknown unknown Masaki As sister to the 1st Emperor of Jurai, Misaki was partnered with a Royal Tree. What we don't know is the generation. At some point, Misaki traveled to Earth in a tree-ship. She later ended up on Earth's moon, where 'today' she still remains in astral form. Her tree is still alive, which is how Misaki still has an astral form. Beyond that, we don't know all the details of how she ended up on the moon, though the Japanese certainly have greater knowledge of it (which is why we desperately need translators).
Honoka 4th Gen Ringo Tatsuki Honoka is part of an experiment performed by Washu Hakubi to increase the power of Royal Trees, which has increased its power to rival that of a 3rd Gen, and given it sentience. Because of this, Honoka sees Washu as its mother.

Honoka was the only success among the 4th Gen Royal Trees, and so the experiment has been halted.


As Tokimi has not yet descended to the third dimension, she has produced no offspring. Some might consider Z her "child", but he was more like someone she manipulated from the outside.


Lufin Family
1st Hierarch
2nd Heirarch
Keira Magma
Geira Magma
(3rd Heirarch)
Kasen Amaki*A
Minaho Masaki
Kiyone Masaki

*Adopted into Jurai'a House Amaki, failed to marry a daughter of Shuzan to connect Airai and Jurai.
**Ties severed with Airai. Airi would have been married to another of the Lufins to double the Airai/Jurai connection.

Yamada Family(J)

Yamada Family
Kai MasakiD
multiple marriages,

Seina's marriages
Seina & Possible Children (chronicled in "Tenchi IF" doujinshi)
Kiriko MasakiD 1 son, marries the daughters of Tenchi & Ryoko and Tenchi & Ayeka.
Amane Kaunaq 1 son, marries the three daughters of Tenchi and Ryo-Ohki
Ryoko BaltaM 1 son, marries the daughters of Tenchi & Noike and Tenchi & Mihoshi. One daughter produced between his union with Noike's daughter
Neju Na Melmas
Jovia Jovis**

*Explained in a "skit" in OVA5, ep.3: Jovia describes herself as marrying Seina as a "plus-one" to a "great beauty." Considering the likely circumstances, the beauty is probably Airen (all were on the planet Barrium at the same time).


Informal, brief family relationships

Hirata Family(K)

Kanemitsu Hirata is a non-royal member of the Jurai Empire. His known relatives are his father, Kaneaki Hirata, his wife, Yuzaki, and his daughter, Mikage.

Shank Pirate Guild(L)

The Shank Pirate Guild expands tens of thousands of years but has few clear relations. Like many guilds, members often take the family name as a mark of inclusion or to honor the guild without any familial relation. Tarant Shank's only known family is his father, Radi Shank, and a brother (both of whom he killed). Hopefully he had no offspring. The novels insinuate he was a necropheliac and/or killed anyone he made love to, so it is unlikely.

Dird Shank has shared features to Tarrant, so there is at least a racial relationship, but no close one. Her parents are deceased, has no siblings, and her only known living relative is her great-great-great-great-uncle.

Balta Kingdom(M)

The Balta Pirate Guild has a long history, but not one comparable to the Shank Guild. They were originally a planet or non-royal family in the Jurai Empire that broke from them to create their own pirate guild and later a Kingdom that was first a protectorate of Jurai, and then a founding member of the Pirate Nation. Like many guilds, members often take the family name as a mark of inclusion or to honor the guild without any familial relation.

Ryoko Balta is a member of the Royal family, an orphan (whose parent's names are unknown), her only living elder relative is her Great-Grandfather, King Balta. She has married Seina YamadaJ in a political marriage, but loves her husband very much. A Doujinshi shows a possible future where her son marries the daughters of both NoikeB and MihoshiF.

Alea Balta has no known relation to the royal family, being from a family that took the name at some point to honor the guild. Her known relatives are her sister, Loretta, and her neice, Melissa. Her former brother-in-law was Alan.

A theory suggests that Jannis, from Spaceship Agga Ruter, is related to the Balta family. The reasoning being that Ryoko's transformation ability could have been an evolved form of Jannis' beastly form.
