How Japan celebrates Halloween: costumes, sweets and Shibuya
Halloween arrived in Japan late and changed on the way. There is very little trick-or-treating and no tradition of carved pumpkins on doorsteps. What there is instead is dressing up, seasonal snacks and drinks, and theme park seasons. Here is what to expect if you are in Japan at the end of October, and the handful of Japanese words that come with it.
A holiday about dressing up
Halloween in Japan is mostly for adults, and it is mostly about 仮装 (kasō), dressing up. Costume shops and variety stores fill up from September, friends and offices hold parties, and the night itself is a reason to go out in costume. Children take part too, usually at an organised event at a nursery, a shopping street or an English class. Nobody goes from house to house.
Seasonal everything
From early September the shops turn orange. Convenience stores, cafés and sweet makers bring out pumpkin flavours and anything with a bat or a ghost on the packet. The words to look for are 期間限定 (kikan gentei), for a limited time only, and ハロウィン限定 (harowin gentei), Halloween edition only. They mean what they say: by early November the shelves have moved on to the next season.
Theme parks and local events
The big theme parks run Halloween seasons for several weeks, often with days when visitors may come in costume under set rules. Towns and shopping streets hold parades and costume events, usually on the weekend nearest the 31st. Check the rules before you go. Many events ask you to change on site rather than travel in costume, and limit masks, face paint and props.
Shibuya, and why it is quieter now
For years the best known Halloween in Japan was the street crowd around Shibuya crossing in Tokyo. After years of crowd trouble, and the crowd crush in Seoul in 2022, Shibuya now asks people not to come for Halloween, bans drinking in the street around the station, and police keep the crowd moving by loudspeaker. The line you will hear most is 立ち止まらないでください (tachidomaranaide kudasai), please do not stop.
The Japanese you need
- ハッピーハロウィン (happī harowin): Happy Halloween. The English, written in katakana.
- トリック・オア・トリート (torikku oa torīto): trick or treat, which children at events will know.
- その仮装、すごいですね (sono kasō, sugoi desu ne): that costume is amazing.
- 写真を撮ってもいいですか (shashin o totte mo ii desu ka): may I take a photo? Always ask first.
- 終電 (shūden): the last train. Trains do not run all night, so know when yours leaves.
If someone answers a photo request with ちょっと… (chotto…) and lets it trail off, that is a polite no. Smile, say すみません (sumimasen) and move on.
Common questions
Do people trick-or-treat in Japan? Rarely, and only at organised events. Going from door to door is not part of the custom.
Is Halloween a holiday in Japan? No. 31 October is an ordinary working day, so parties and events gather on the weekend before it.
How do you say Happy Halloween in Japanese? ハッピーハロウィン (happī harowin), the English phrase in katakana. You will also see Halloween written ハロウィーン, with a long vowel. Both are in use.
In Japan, Halloween is a costume party and a limited edition snack aisle, not a night of knocking on doors.
