Yokai have existed in Japanese folklore for centuries, coming into fruition during a time no one can quite place. However, it wasn’t until the 17th century that people began to openly appreciate the art and history of yokai.

One person who assisted in the widespread popularity of yokai during the Edo period was Toriyama Sekien, a printmaker who became known as the father of the very first definitive encyclopedia of yokai monsters to ever exist.

Through the technique of woodblock printing, Toriyama was able to catalogue all yokai monsters known to exist. From their appearances, habits, characteristics, locations, and more, Toriyama could truly showcase to all of Japan, and eventually the world, the extent to which yokai monsters lived and breathed around us.

There are literally hundreds (and counting) of yokai monsters that are known across Japanese folklore. Let’s get to know some of the most popular ones now.

The 20 Most Popular Yokai in Japan

1. Tengu

Traditional Japanese Masks - Tengu

Tengu is a legendary yokai that you’d likely have come across whilst exploring Japan. This popular folklore creature is often printed on arts and crafts and is featured in many cultural performances.

Tengu is depicted as an evil-looking long-nosed creature, with an almost bird-like face. Tengu’s sole purpose is to deviate people away from the pathway to enlightenment through their magical skills and mischievous behavior.

Some shrines will display tengu statues, as they believe that Tengu will help them ward off evil spirits.

2. Oni

Akita City Japan - Namahage 

Arguably one of the most famous yokai in Japan, the Oni is an ogre who is strong, fearsome, and mischievous. They are known to bring bad luck and disaster with them wherever they go. They are originally from hell and legends tell it that they occupy desolate and abandoned areas.

Every year, the day before springtime, Japanese people celebrate ‘Setsubun’. During this festival, you will witness kids throw beans at Oni (adults dressed up in masks) in an attempt to drive them away and achieve good luck for the rest of the year.

3. Umi-bozu

Umi-bozu Yokai

This sea creature is usually described as having a huge dark head that just appears out of the water. It’s said that when it appears, it will break through any boat that is nearby and kill its passengers.

If it doesn’t, it will approach the ship and request a bucket; however, it will still drown the poor souls on the ship even after receiving a bucket. If you want to trick the Umi-bozu, you must give him a bucket without a bottom and confuse him, hopefully gaining you enough time to escape.

Kappa is a popular water monster, often depicted as a cute cross between a turtle and a boy. However, Kappa has a long and dark history. It is said that Kappa lives in the water, and if anyone gets too close to the water edge, they will lure them into the water and then drown them.

Gashadokuro Yokai

The Gashadoruko is one of the scariest yokai known to mankind. It is depicted as a gigantic skeleton (think up to 15 times the size of humans!), and its bones are made up entirely of people who have died in the past but haven’t been buried properly.

The Kasa-obake is one of the first known instances of yokai that is not specifically an animal but rather an object. In Japan, objects are believed to be capable of having ‘spirits’, and so when things get older, it is more likely that they’ll possess a spirit.

20. Aka Manto

Aka Manto Yokai

The Aka Manto yokai is a malevolent evil spirit that haunts public or school toilets, awaiting its next young victim. It is said that once the Aka Manto spirit selects its victim and presents itself, there is no escaping.
