Sakanoue no Tamuramaro
The name "Hirano" probably goes back to the end of the Heian period, and was formally known as Hirano-shou in Sumiyoshi-gun (district) of the Settsu province. The second son of Sakanoue no Tamuramaro, Sakanoue no Hirono, was the feudal lord in charge of the development of Hirano and was called "Hirano-tono" ("tono" being the title given to noblemen).
