Jaso or Jassu, formerly known as Yashogarh was a princely state of the Bundelkhand Agency in British India located in present-day Nagod tehsil, Satna district, Madhya Pradesh, 44 km west from the district headquarters.

Jaso State was founded in 1732 by Bharti Chand, younger brother of Raja Hrideshah of Panna.

Around 1750, it was split into Bandhora and Jaso, being reunited later in the eighteenth century.

In 1816 Jaso State became a British protectorate.

[citation needed] Rulers bore the title of Diwan[1][2] Durjan Singh and Medni Singh ruled as the Dewans of Bandhora when the state was split from Jaso in the 18th century.
