Japanese Superstitions: Numbers, Chopsticks and Night Habits

Like every culture, Japan has a collection of superstitions, and a handful of them come up in daily life. Several share one theme: avoiding sounds, numbers or actions that recall death and funeral rites. That explains why 4 can be avoided in room numbers, why some chopstick habits are frowned on, and why a pillow facing north can raise an eyebrow. Others are simple old sayings about the night. This guide covers the ones you are most likely to meet, what lies behind them, the phrases people use when they come up, and how lightly most people actually take them.

Four and nine can be avoided because their readings sound like death and suffering

Two chopstick habits mirror funeral rites and are considered bad manners

Sleeping with your head to the north recalls how the deceased are laid

Most people treat these lightly, but some habits are worth adopting anyway

The words for luck

When a superstition comes up, the key word is engi, which refers to omens and fortune. Something unlucky is engi ga warui; something that brings good fortune is engi ga ii. You will hear both in conversation, often half-joking.

Meishin means superstition, and adding it signals that you do not take the belief too seriously.

JapaneseRomajiMeaning
縁起がいいengi ga iiLucky, a good omen
縁起が悪いengi ga waruiUnlucky, a bad omen
迷信meishinSuperstition
〜と言われています。... to iwarete imasu.It is said that ...
迷信だけどね。Meishin da kedo ne.It's just a superstition, though.

Four and nine

The number four has the reading shi, which sounds like shi meaning death. Nine can be read ku, which sounds like ku meaning suffering. Because of this, both numbers are sometimes avoided in situations linked to health, life and celebration.

In practice, you may notice missing room numbers in some hospitals, hotels or apartment buildings, and people avoid giving gifts in sets of four. In ordinary counting, the readings yon and kyū are used, which sidesteps the problem.

JapaneseRomajiMeaning
四shi / yonFour: shi sounds like death
死shiDeath
九ku / kyūNine: ku sounds like suffering
苦kuSuffering
4号室がないんですね。Yon-gō-shitsu ga nai n desu ne.There's no room number four.
4つセットは避けたほうがいいですよ。Yottsu setto wa saketa hō ga ii desu yo.It's better to avoid a set of four.

Chopstick habits to avoid

Two chopstick habits are linked to funeral customs and are widely considered bad manners. The first is standing chopsticks upright in rice, which resembles rice offered to the deceased. The second is passing food from one pair of chopsticks to another, which mirrors how family members pass bone fragments after a cremation.

These are worth following even if you do not care about superstition, because people genuinely notice them. If you want to share food, place it on the other person's plate instead.

JapaneseRomajiMeaning
箸を立てないでね。Hashi o tatenaide ne.Don't stand your chopsticks up.
お皿に置いてください。O-sara ni oite kudasai.Please put it on the plate.
箸置きhashiokiChopstick rest
お葬式を思い出すから。O-sōshiki o omoidasu kara.Because it reminds people of a funeral.

Sleeping facing north

Kita-makura, a pillow to the north, describes sleeping with your head pointing north. The deceased are traditionally laid this way, so some people avoid it for everyday sleep.

Plenty of people ignore it, and some even say it is healthy. It mainly comes up when arranging a room or at a homestay, where a host might mention it with a smile.

JapaneseRomajiMeaning
北枕kita-makuraSleeping with your head to the north
北枕は縁起が悪いって言われています。Kita-makura wa engi ga warui tte iwarete imasu.People say sleeping facing north is unlucky.
気にしない人も多いです。Ki ni shinai hito mo ōi desu.Lots of people don't mind.

Things not to do at night

Some superstitions are old warnings about the night, which were often practical once: keeping quiet after dark, or not handling blades in poor light. Today they survive mainly as sayings that parents repeat to children.

Two you may hear are that whistling at night brings snakes, and that cutting your nails at night means you will not be with your parents when they die.

JapaneseRomajiMeaning
夜に口笛を吹くと、蛇が来る。Yoru ni kuchibue o fuku to, hebi ga kuru.Whistle at night and a snake will come.
夜に爪を切ると、親の死に目に会えない。Yoru ni tsume o kiru to, oya no shinime ni aenai.Cut your nails at night and you won't be there when your parents die.
子どものころ、よく言われました。Kodomo no koro, yoku iwaremashita.I was often told that as a child.

Lucky days and lucky things

Not everything is about bad luck. Some calendars show six rotating day labels, and a few matter for events: taian is considered a lucky day for weddings, while butsumetsu is considered unlucky, and tomobiki is often avoided for funerals.

Lucky objects are common too, such as the beckoning cat in shops and daruma dolls for goals. People enjoy them as charms and decoration.

JapaneseRomajiMeaning
大安taianA lucky day, popular for weddings
仏滅butsumetsuAn unlucky day
友引tomobikiA day often avoided for funerals
招き猫maneki-nekoBeckoning cat, a charm for business
だるまdarumaDaruma doll, used for goals and wishes

Most people treat these lightly. Follow the chopstick etiquette and avoid fours in gifts, and you can enjoy the rest as interesting conversation.

FAQ

Frequently asked questions

Why is the number 4 unlucky in Japan?

One reading of 4 is shi, which sounds the same as the word for death. For that reason, some hospitals and hotels skip room numbers with 4, and people may avoid giving gifts in sets of four. The more common reading yon is used in everyday counting.

Is it really rude to stick chopsticks upright in rice?

Yes, this is one people genuinely notice. Chopsticks standing in a bowl of rice resemble an offering made for the deceased. Rest them on a chopstick rest or across your bowl instead.

Do Japanese people really avoid sleeping facing north?

Some do, especially older people, because the deceased are traditionally laid with the head to the north. Many others do not mind at all. It is a common point of curiosity rather than a strict rule.

Are superstitions taken seriously in Japan?

Mostly lightly. People may joke about them or follow them out of habit without really believing. The chopstick etiquette and the avoidance of four in gifts are the ones most worth following, because others notice.
