Kaidan: Japanese Ghost Stories and the Words to Tell Them

Kaidan (怪談) are Japanese ghost stories: 怪 means strange or uncanny and 談 means talk. They are a summer tradition, because a good shiver is said to cool you down in the heat.

Kaidan: Japanese Ghost Stories and the Words to Tell Them

In much of the English-speaking world, ghost stories belong to autumn and Halloween. In Japan they belong to August: haunted houses open at amusement parks, television runs ghost specials, and children dare each other to walk through dark temple grounds. This guide explains the word kaidan, sorts out the three words that English lumps together as ghost (yūrei, obake and yōkai), and introduces three stories that most Japanese adults know by name. Then it turns practical: the small connecting words that make a spoken story work, such as suru to and sono toki, and the natural ways to say that a story gave you goosebumps.

Kaidan are ghost stories; in daily speech people say kowai hanashi

Yūrei are dead people's spirits; yōkai are folklore creatures

Summer is ghost season: Obon, haunted houses and tests of courage

Zotto shita and torihada ga tatta say a story chilled you

What kaidan means

Kaidan is written 怪談: the first kanji means strange, suspicious or uncanny, and the second means talk or tale. It covers old tales of vengeful spirits, modern school ghost stories and anything in between. The word has a classic ring. When friends swap stories today they usually call them kowai hanashi (怖い話), scary stories.

You may have seen the spelling Kwaidan. That is an older way of writing the same word in Roman letters, used by Lafcadio Hearn as the title of his 1904 collection of Japanese ghost stories in English.

Yūrei, obake, yōkai: who is who

ReadingWhat it isTypical image
yūreiThe spirit of a dead person who cannot rest, often because of a grudge or a regretWhite burial kimono, long loose black hair, often drawn without feet
obakeA loose everyday word for anything spooky; literally a thing that has changed formCartoon ghosts, the monsters in a haunted house
yōkaiSupernatural creatures of folklore that were never humanThe kappa river imp, the long-nosed tengu, shape-changing foxes

Obake comes from the verb bakeru (化ける), to change shape. It is the word children use, and it sounds softer than yūrei. If you say yūrei, listeners picture a dead person with unfinished business.

Why ghost stories belong to summer

Ask a Japanese person and you will usually hear two explanations. The first is Obon, the days in mid-August (July in some areas) when the spirits of ancestors are believed to come home. The dead are on everyone's mind. The second is temperature: Japanese describes fear as cold. Your spine goes cold, you shiver, you get gooseflesh. Before air conditioning, a frightening story was said to be a way of cooling down.

Whatever the mix of reasons, the season is now fixed: haunted houses, ghost programmes on television and tests of courage all arrive with the heat.

JapaneseRomajiMeaning
夏といえば怪談です。Natsu to ieba kaidan desu.Summer means ghost stories.
怖い話で涼しくなります。Kowai hanashi de suzushiku narimasu.Scary stories cool you down.
背筋が寒くなりました。Sesuji ga samuku narimashita.A chill ran down my spine.

Three stories everyone knows by name

JapaneseRomajiMeaning
一枚、二枚、三枚ichimai, nimai, sanmaione plate, two plates, three plates
一枚足りない。Ichimai tarinai.One is missing.
  • Yotsuya Kaidan (四谷怪談): Oiwa, called Oiwa-san (お岩さん), is betrayed and poisoned by her husband, and returns with a disfigured face to haunt him. It is best known from a kabuki play first staged in 1825.
  • Banchō Sarayashiki (番町皿屋敷): Okiku (お菊), a servant blamed for a missing plate from a precious set of ten, dies in a well. At night her voice counts the plates, one, two, up to nine, and never reaches ten.
  • Miminashi Hōichi (耳なし芳一), Hōichi the Earless: a blind lute player is called out night after night to perform for the ghosts of a defeated clan. A priest writes holy text all over his body to hide him, but forgets the ears.

Okiku counts with mai (枚), the counter for flat things such as plates and paper. Count plates slowly in a low voice and Japanese listeners will think of her at once. The plain form tarinai suits a ghost talking to herself; in normal polite speech you would say ichimai tarimasen.

Kimodameshi, haunted spots and a hundred stories

Kimodameshi (肝試し) is a test of courage. Kimo is the liver, the old seat of bravery, and tamesu means to test. It is a standard event at summer camps: pairs walk a dark route while friends hide and jump out.

A shinrei supotto (心霊スポット) is a place with a haunted reputation, such as an old tunnel or an abandoned building. Visiting one at night is a well-known pastime among young people, but many of these places are private property, so enjoy the stories and skip the visit. Hyakumonogatari (百物語), a hundred tales, is an old parlour game: people take turns telling stories and put out one light after each, and when the last light goes out something is said to appear.

JapaneseRomajiMeaning
肝試しに行きませんか。Kimodameshi ni ikimasen ka.Shall we go on a test of courage?
ここは心霊スポットです。Koko wa shinrei supotto desu.This place is a haunted spot.
ここは出るそうです。Koko wa deru sō desu.They say this place is haunted.
幽霊を信じますか。Yūrei o shinjimasu ka.Do you believe in ghosts?

Deru (出る) only means to come out, but in this context everyone understands what comes out. Saying koko, deru rashii yo in a low voice is how many real ghost stories begin.

Telling a story aloud: the connecting words

Folk tales open with mukashi mukashi (昔々), once upon a time. Modern ghost stories open by naming the source: a friend, a senior at school, a taxi driver. After that, three small tools do most of the work. The ending sō desu after a plain verb marks hearsay, so you can pass on what you were told. Suru to (すると) means and then, with a hint of surprise at what follows. Sono toki (その時), at that moment, slows the story down just before the scare.

JapaneseRomajiMeaning
昔々、あるところにmukashi mukashi, aru tokoro nionce upon a time, in a certain place
これは友達から聞いた話です。Kore wa tomodachi kara kiita hanashi desu.This is a story I heard from a friend.
夜中に音がしたそうです。Yonaka ni oto ga shita sō desu.They say there was a sound in the middle of the night.
すると、ドアが開きました。Suru to, doa ga akimashita.And then the door opened.
その時、声が聞こえました。Sono toki, koe ga kikoemashita.At that moment, I heard a voice.
振り返ると、誰もいませんでした。Furikaeru to, dare mo imasen deshita.When I turned around, nobody was there.

Reacting to a scary story

JapaneseRomajiMeaning
怖い!Kowai!Scary!
怖かったです。Kowakatta desu.That was scary.
ぞっとしました。Zotto shimashita.It gave me the chills.
鳥肌が立ちました。Torihada ga tachimashita.I got goosebumps.
怖い話は苦手です。Kowai hanashi wa nigate desu.I'm not good with scary stories.
今夜は眠れません。Kon'ya wa nemuremasen.I won't be able to sleep tonight.
それで、どうなったんですか。Sorede, dō natta n desu ka.And then what happened?

Kowai covers both it is scary and I am scared, so a single kowai is a complete reaction. Zotto suru is the sudden cold shiver, and torihada ga tatsu is gooseflesh. The last line, sorede dō natta n desu ka, is the best gift you can give a storyteller: it asks for more.

Key points

A practical way to improve

A ghost story is a perfect speaking exercise because it forces you to put events in order. First, retell the plate-counting story of Okiku in four sentences, using sō desu for the parts you heard from others. Second, record yourself telling a thirty-second story with suru to and sono toki, and slow down before the scary line. Third, in Unihongo's immersive 3D classroom, ask your AI Sensei to play a friend at a summer camp: tell your story, then ask the Sensei for one and react with kowai, zotto shimashita or torihada ga tachimashita. The session report afterwards lists corrections, so check your past-tense endings and whether your connecting words were natural.

  1. 1

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

What does kaidan mean in Japanese?

Kaidan (怪談) means a ghost story or tale of the uncanny. The first kanji means strange or mysterious and the second means talk or tale. It has a slightly old-fashioned, literary feel; in everyday conversation people more often say kowai hanashi, a scary story.

Why are ghost stories told in summer in Japan?

Two reasons are usually given. Obon, in mid-August in most regions, is when the spirits of ancestors are believed to return home, so the dead feel close. And fear is described as a chill in Japanese, so a scary story is said to cool you down on a hot night.

What is the difference between yūrei, obake and yōkai?

A yūrei is the spirit of a dead person, often one with a grudge. Yōkai are supernatural creatures of folklore, such as the kappa and the tengu, and were never human. Obake is a loose, child-friendly word for anything spooky, and can cover both.

What is kimodameshi?

Kimodameshi (肝試し) is a test of courage, literally a test of the liver. In summer, children and students walk in pairs at night to a spooky place such as a graveyard or a shrine and come back, while friends hide along the route to frighten them.

How do you say I got goosebumps in Japanese?

Say torihada ga tachimashita (鳥肌が立ちました), or casually torihada ga tatta. Torihada is literally bird skin. For a cold shiver of fear you can also say zotto shimashita. Both are natural reactions after hearing a scary story.
