Japanese Elevators Don’t Have The 4th Floor Button. Here’s Why.
Tetraphobia in East-Asian Countries — The number “4” in Japanese pronounced shi – 四 sounds similar to the Kanji 死 (also shi) whose meaning is death. The Japanese thus believe the number 4 to be associated with death. While studying Japanese, I stumbled across this and realized they take this superstition seriously. Wikipedia terms this as Tetraphobia. Henceforth you’ll find apartment and hospital elevators skipping floor numbers 4, 14, and 24.
