In all honesty, I didn't even remember that Ueda also did Yumi way back when. Simply because maybe for a few other roles back then (Petopeto-san, kasimasi, and Gakuen Alice off the top of my head), I've seen Ueda typcasted into roles that had the kansai-ben accent and/or significant amounts of tsun in the character. I certainly don't remember Ueda doing any Yumi-like characters in recent memory; on the contrary, her roles in the past couple of years lean towards Sachiko's more than anything else.
