Higashikata Family

The Higashikata (東方) Family is one of the main families of the JoJo's Bizarre Adventure series. Connected the Joestar Family, its members are usually on the side of good. Unlike the Joestar, the Higashikata exclusively reside in the town of Morioh.

Diamond is Unbreakable
The Higashikata (東方) family is first seen in Diamond is Unbreakable and consists of three family members. They reside in the suburb of Morioh in a detached house and seem to be middle-class. Josuke, being the son of Joseph Joestar, is the only member having a Stand, Tomoko and Ryohei being ordinary humans who are left out of the former's adventures.

JoJolion
In the new continuity of Steel Ball Run and JoJolion, a new more peculiar Higashikata family comes to the forefront. Unlike the first iteration, they are more deeply connected to the supernatural and have more quirks.

The first Higashikata featured is Norisuke Higashikata, a mature Japanese man who competes in the Steel Ball Run race. After the race, he started a successful fruit selling business in the Higashikata Fruit Company, eventually making the family a respected well-off part of Morioh's community. They also all reside within the Higashikata House in the middle of a large estate of garden and orchards, and whose soil presents the supernatural property of being able to mix buried bodies' characteristics.

However, the strangest thing about them is that the Family is cursed with a Rock Disease changing each generation's eldest child into rock, a curse which afflicted the family for a long undisclosed period of time. Thus, the Higashikata follow several traditions around countering this curse. The eldest son notably has to crossdress to ward off the curse, and they previously had to make the second son the heir or anyone marrying the eldest daughter the new head of the family. However, they have since Norisuke IV's time, have an unofficial trend of having a parent sacrifice themselves for the child by performing a transfer of the curse. A tradition which Kaato Higashikata broke.

This Higashikata family follows a tradition whereby the eldest son of each generation changes his birth name to "Norisuke", possibly when he fathers a son himself or when the previous Norisuke passes away, as seen in the case where Jobin Higashikata has not taken up the name "Norisuke V".

The family tree as revealed in JoJolion lists its members from right to left from eldest child to youngest child. Interestingly, the names of the siblings of each "Norisuke" in each generation are not revealed in the family tree. The tree also demonstrates a bloodline connection to the (SBR Universe) Joestar Family through Rina Higashikata, intertwining the two families.

Lastly, most if not all of the Higashikata are Stand Users, although the circumstances of this ability's acquisition are undisclosed.
