....Legendary Empress Jummu (Sanohiko)
She was the descendant of the Sun Goddess and was succeeded by grandson. 

Ca. 188-248 Queen Himiko of Yamataikoku
卑弥呼 also referred to as Pimiko, she was ruler of an ancient state-like formation thought to have been located either in the Yamato region or in northern Kyushu of present-day Japan. Few records are available and little is known about her, and the location of Yamataikoku is the subject of a great, often emotionally charged, debate that has been raging since the late Edo period. According to an ancient Chinese history book, Chronicles of the Three Kingdoms she was a shaman who controlled people through her paranormal abilities. The Nihonshoki, an old Japanese history book, notes that Himiko was actually Empress Jingū Kogo, the mother of Emperor Ōjin, but historians disagree. Some speculate that she is conflated with Amaterasu, the Japanese sun goddess. The Chinese chronicles book from 297 refers to the inhabitants of the Japanese islands simply as the Wa, literally, "The Little People", and dscribes a fragmented political structure of more than a hundred or more separate tribes, nominally ruled by a female shaman. According to an ancient Korean history book, Samguk Sagi, she sent an embassy to King Adalla of Silla in May 172. However, Chinese history books record Silla as having been established on 356, which casts doubt on this claim. Himiko never married and it is recorded that her younger brother assisted her as a political advisor. She is said to have had one thousand female servants and to have never appeared in public. There are indications that a tribal king, posthumously now known as Emperor Shujin, raised military host against her or her successor - reportedly another shamaness, her niece or other relative, ultimately conquering their position and establishing male rule with headquarters in central Japan. Himiko may have been a chinese corruption of himemiko, princess-priestess, or lady shaman. The name is said to mean "Sun Daughter" and there are also assessments that she is the real person upon whom the myth of sun goddess Amaterasu is built. Also Known as Yamatohime no Mikoto (d. 248)
