I found it intresting that the neckless that Rokudo Sannin is wearing is one the the legendary three items of japan or the Imperial Regalia
The Imperial Regalia of Japan (三種の神器, Sanshu no Jingi?), also known as the Three Sacred Treasures, consist of the sword, Kusanagi (草薙劍), the jewel or necklace of jewels, Yasakani no magatama (八尺瓊曲玉), and the mirror Yata no kagami (八咫鏡). Also known as the Three Sacred Treasures of Japan, the regalia represent the three primary virtues: valor (the sword), wisdom (the mirror), and benevolence (the jewel). These may be connected with Buddhist thought.
Due to the legendary status of these items, their locations are not confirmed, but it is commonly thought that the sword is located at Atsuta Shrine in Nagoya, the jewel is located at Kokyo (the Imperial Palace) in Tokyo and the mirror is located in the Grand Shrine of Ise in Mie prefecture [1]. One or more of these may not be the originals.
The neckless in paticular is called Yasakani no Magatama and is
The most important magatama is the Yasakani no Magatama (八尺瓊曲玉, also 八坂瓊曲玉), which is part of the Imperial Regalia of Japan, added some time around the Heian period. The Yasakani no Magatama stands for benevolence, and is one of the three items used in the ceremony of imperial ascension. In Japanese mythology, the jewels, along with the mirror, were hung on the tree outside of Amaterasu's cave (where she had hidden) to lure her out. It is believed to be a necklace composed of jade magatama stones instead of a solitary gem as depicted in popular culture. It is believed to be enshrined in Kokyo, the Japanese Imperial Palace.
I found this all especailly intresting considering that the neckless stands for benevolence, which is kinda of the what pain wants to bring to the naruto world. Also its possible that the sword that Rokudo Sannin has at his back could be the orginall Ksunagi sword meaning that etheir Orochimaru recovered it or both Sasuke/Oro's are fakes. I think its kinda of cool that kishi gave Rokudo the three acient treasures of japan and they may even play a role in his power/ninjutsu/ninjutsu creation but even if they don't i just found it intresting so i decieded to post it.
this is all copy paste i was reserching on google

but im looking for more information on hyuuga clan tree on japanese magazines lol
