Number 4 Is Unlucky
WHAT PEOPLE BELIEVE
The number 4 is deeply unlucky and should be avoided. Many buildings skip the 4th floor. Hospitals skip room 4. Gifts should never come in sets of 4.
HISTORICAL ORIGIN
In Japanese, the number 4 can be pronounced "shi" (四), which is a homophone for "shi" (死) meaning "death." This linguistic coincidence created one of the strongest superstitions in East Asian culture, shared with China and Korea.
THE REAL REASON
It's purely a linguistic coincidence — a homophone creating an association that doesn't exist in reality. The number 4 has no inherent connection to death. But the belief is so deeply embedded that it affects real estate prices (4th floor apartments are cheaper), product design, and even hospital practices.
THE MODERN TWIST
In 2026, you can literally get a 4th-floor apartment in Tokyo for cheaper because of this. Smart expats specifically request floor 4 for the discount. Tech companies designing products for the Japanese market still avoid the number 4 in model names, pricing, and packaging. A linguistic coincidence from centuries ago is still shaping UX design.
VERDICT
This one doesn't hold up to scrutiny. Pure myth, no substance.
FUN FACT
This fear has its own name: tetraphobia. Japan uses the alternative pronunciation "yon" for 4 to avoid saying "shi." So they literally invented a workaround pronunciation for a number.

Sticking chopsticks vertically into a bowl of rice is extremely taboo. It's considered one of the worst things you can do at a dinner table — deeply offensive and inviting death into the home.
Don't Sleep Facing North
Sleeping with your head pointing north (called "kita makura") brings bad luck or death. It's considered so unlucky that most Japanese people consciously avoid this sleeping position.
Hide Your Thumbs When a Hearse Passes
When a funeral hearse or procession passes by, you should quickly hide your thumbs by tucking them inside your fists. If you don't, your parents will die early, or you won't be present at their deathbed.
