A Cat’s Face Washing Activity Can Fetch Rain the Following Day

Cats are considered to be immensely sacred in Japanese culture and it’s believed that if a cat washes its face, it will rain the next day.

This superstition may have stemmed from the fact that cats have the capability of smelling the moisture in the air. Or it is basically because cats absolutely dislike having wet whiskers. And that is probably why they take care of their face when there’s a lot of humidity present in the air. And humidity often means impending rain.

Even though it has not been scientifically proven yet, this superstition is quite common amongst Japanese people.

Your Body Gains Flexibility After Drinking Vinegar


People of Japan consider vinegar to be extremely healthy. This is because it cleanses your body from within. Even if there is no proven scientific reason behind this superstition, people mostly consider it to be the truth. And surprisingly, many people adhere to the same and practice consuming vinegar to cleanse their bodies.

Cleaning House on New Year’s Day is Prohibited

As per the traditions of Shinto, Japanese people consider New Year’s Day to be the most sacred of all. This day is believed and meant to gracefully welcome all the gods and goddesses into a new year.

So, if you consider cleaning your house on that day, you deliberately push away the gods for the entire year. Even if it is just mere superstition, would you ever take a chance to risk your luck? No, right? So, you should at least not clean your house on New Year’s day.

No Whistling at Night

There are many reasons why whistling at night is considered a bad omen. In feudal Japan, bandits and cutthroats would communicate at night using whistles and tunes. Combined with the belief that whistling at night can attract spirits and actual snakes, the Japanese believe that you should never whistle while traveling alone at night or while getting ready for bed.

Hide your Thumbs When you See a Hearse

It’s a common belief in Japanese culture that the spirits of the dead can enter through the narrow gaps between your fingernails.

Why they won’t enter through a more obvious opening – we don’t really know.

So, when a Hearse or funeral car is passing by, or you’re driving through a graveyard, it’s highly recommended that you hide your thumb inside your palms. Doing so will help prevent the spirits — inhabiting the hearse or the graveyard — from possessing you.

Also, since the Japanese translation for thumb means “Parent Finger”, this implies that your parents might also face an untimely demise if you fail to hide your thumbs.

Don’t Hang Laundry at Night

Kimonos were expensive, and instead of buying new ones, most Japanese folk would use the old clothes of their parents or grandparents. But the belief was that the spirits of their ancestors could linger nearby and possess the clothing when they put them out to dry overnight. This superstition is tied to the notion that the spirits of our ancestors like to roam around at night and cling desperately to their old possessions.

Cover your Belly Button During a Thunderstorm

In Japanese mythology, the God of thunder and lightning Raijin, was said to be a very eccentric character who often had a hunger for children’s belly buttons.

So, to avoid Raijin from striking down young children, elders would encourage the kids to cover their torso’s.

Although a belly button doesn’t attract lightning per se, it was a clever tale to encourage children to stay indoors and not catch a cold.

Don’t Lie Down After a Meal

Another cunning tale devised by Japanese parents to keep their children from being lazy, was to warn them that whoever takes a nap or lounges around after a meal would turn into a cow.

Although a post-lunch dip or food coma can be compared to the lethargic and sluggish behavior of a cow, it’s not realistically attainable.

Don’t Climb Persimmon Trees

The Persimmon tree has fragile branches, and it’s highly symbolic of life and death in Japanese culture.

Considering death, Persimmon trees were used to mark gravestones, and their wood was also used as fuel for cremations.

On the flip side, people would string together dried persimmons and hang them on the doorways of their homes during New Year’s Eve for good luck and prosperity.

Whatever the case, climbing persimmon trees is frowned upon since it’s dangerous for little children, and it’s believed that someone who falls from the tree will die within three years.

Never Write a Person’s Name in Red Ink

Speaking of gravestones, it’s very common in Japan, Korea, and China to mark the gravestones of the dead in red ink. As such, if you write a person’s name in red ink, it’s considered a bad omen as it signifies death.

Kill Spiders at Night

Finding spiders inside your house or on your travels in the morning and daytime is considered a sign of good luck. In Japanese culture, the spider is revered as an honorable guest while the sun is out.

However, at night, spiders tend to have the opposite effect, resembling a thief. So, if you meet one at night, it’s tradition to chase it away or kill it, lest it bring bad luck.

Watch out for the Crow’s Cry

Similar to the canary in the coal mine, Crows are also said to be able to predict subtle changes in the environment. In Japan, crows are said to predict earthquakes, so it’s crucial that you “heed their caws” as it can imply imminent earthquakes, which Japan is all too familiar with.

Also, in Japanese mythology, there’s a divine messenger called Yatagarasu, who takes on the form of a crow and heralds the Gods, especially when they’re trying to meddle in human affairs.

So, in the spiritual context, the caws can signify that someone will die immediately due to an illness or an accident.

Be Careful While Living Through a Certain Age

It is also common knowledge that the ages of 25, 42, and 61 are particularly unlucky for men, whereas 19, 33, and 37 are ill-fated for women.

Also, the years before and after this particularly luckless year are said to be cursed, so it’s customary for Japanese adults to be purified at a temple or shrine when they reach these ages.

Don’t Disturb a Pile of Salt

Japanese consider salt to have cleansing properties, implying that it can fully clean a person of spirits and maladies, ward off evil, and attract good luck and fortune.

Because of this, you might often find salt piles scattered on the entrances of homes whenever there’s a funeral nearby. Also, salt piles are constructed during weddings and sumo matches.

Don’t Swim During Obon Season

The Japanese version of Halloween is the Obon season which is observed for an entire week in mid-August. This season is dedicated to the dead so they can revisit their relatives.

Spiritually, the Japanese believe that the dead travel to the realm of the living through the rivers, similar to the River Styx but in the opposite direction.

Locals believe anybody caught swimming will be swept away by the tide and carried off into the underworld. Surprisingly, this superstition holds some weight as the currents can be strong in the summer season.

Wrapping Up

Because of Japan’s rich, long history, it’s no surprise that there are so many superstitions that have emerged from this culture. These superstitions may appear strange to someone not used to them, but to many Japanese people, it’s a part of their culture.
