Arai Hakuseki
Extensive study has gone into trying to ascertain her place of birth, her family and so on, but without conclusive results. The Edo-period scholar Arai Hakuseki advanced the theory that there was more than one woman named Komachi and that the legends about her referred to different people. This theory was later expanded to conjecture that there were four "Komachis". It has been conjectured that she was a in the service of Emperor Ninmyō, and when the latter died in 850 she started relationships with other men.
