He looked completely ridiculous with the fake epicanthic folds.
There were a couple of Mission: Impossible
episodes where Leonard Nimoy's Paris disguised himself as an Asian with fake epicanthic folds and a fake accent, presumably because he looked "exotic" to casting directors at the time. I could marginally buy it in the one where he was playing a Chinese advisor to a communist movement in a Latin American country, presuming that they hadn't met any actual Chinese people before, but it was ridiculous in the episode where he played a Japanese person in Japan
and the Japanese people around him didn't instantly see through his disguise. (Although, to the episode's credit, they were all played by genuine Asian actors.)
