[1] Richard Ponsonby-Fane divides the history of the Aso clan into three stages[4] The Aso clan originally descended from Kamuyaimimi, a son of Emperor Jimmu and Himetataraisuzu-hime.

[1] It is speculated that many members may be buried in Nakadori Kofun Group [ja].

[1]In recorded history the family started as Imperial representatives called Kuni no miyatsuko.

Powerful military families like Shimazu and Omura also became strong competitors.

Kato Kiyomasa got control of the Higo province and helped the Aso family.

They remained in prominence until the 16th century as their feudal lord continued to rule over half of what is now known as Kumamoto Prefecture.

It also made it possible for them to establish branches of the Aso shrine in other locations.
