Halloween in Japanese

For reference, an article about "Halloween," in Japanese: Harouin ハロウィン, including a list of common Halloween words and practices.

Characters trick-or-treating in Halloween.

Anime: Osomatsu-san おそ松さん (Episode 3)

Context: yay for cultural appropriation!

Translation

There's no native Japanese word for "Halloween." Instead, the term gets loaned into Japanese through katakanization of the English word "Halloween."

harowin
ハロウィン
Halloween.
harowiin
ハロウィーン
Hallowe'en.
(alternative transliteration.)
harowin paatyi
ハロウィン・パーティ
Halloween party.
harowin ebento
ハロウィン・イベント
Halloween event.

Some others Halloween traditions with English names also get the same treatment, like trick-or-treat and jack-o'-lantern.

Date

Halloween in Japan occurs in the same date as it does everywhere else in the world:

jyuu-gatsu san-jyuu-ichi-nichi
１０月３１日
Month 10, day 31 (October)
(this is how dates are written in Japanese, yes)

Wearing Scary Costumes

In Halloween there's a custom costume custom where people of all ages make or order costumes to wear.

Costume. Disguise.
- Written with the kanji for "temporary" and "attire."
kasou suru
仮装する
To wear a costume. To disguise yourself.
kasou paatyii

Disguising yourself with a costume is a thing, but it's not the same thing as:

kosupure
コスプレ
Cosplay. Costume play. Having fun dressing in a costume.
ishou
衣装
Garment. Clothing. (part of a costume.)
fuku
服
Clothes. (normal clothes)
kiru

To be wearing.

The practice of wearing costumes sometimes involves disguising yourself as the opposite gender, that is, crossdressing.

iseisou

(literally written with the kanji for "different," "sex," "attire")
josou
女装
Crossdressing. Wearing female clothing.
(literally "woman attire")
dansou
男装
Crossdressing. Wearing male clothing.
(literally "man attire")

Originally it was about pretending to be an evil spirit, so the costumes were really scary. But then with horror films people started dressing up as popular horror film villains and popularized versions of monsters and creatures. Nowadays they dress up as stuff that's not even scary anymore.

kowai
怖い
Scary.
osoroshii
恐ろしい
Dreadful.
kyoufu
恐怖
Fear.
kyoufu wo ataeru
恐怖を与える
To give fear. To instill fear.
