What was the original, harsher term for Poka-Yoke, and why was it changed?

Answer

Baka-yoke, because it was offensive to the 'respect for people' culture

The initial terminology was *baka-yoke*, meaning 'fool-proofing,' but it was updated in 1963 to Poka-Yoke because the harsher term was not conducive to a culture built on respect for people.
