Spoon & Tamago has published a selection of costumes from Japan’s 2026 Jimi Halloween, a tradition built around portraying ordinary situations and people. The report credits the event’s origins to a 2014 gathering by Daily Portal Z staff and says the publication has covered it since 2018.
Spoon & Tamago has published a roundup of costumes from Japan’s 2026 Jimi Halloween, where participants portray familiar, often awkward everyday situations rather than traditional spooky characters. The annual event offers an alternative to elaborate Halloween outfits, with this year’s examples including someone struggling with a designer faucet and a diner who mistook a muddler for a straw.
The costumes featured in the report turn small social moments into recognizable characters. Examples include a person trying to arrange a group photo in a cramped izakaya, someone hesitating before asking whether it is all right to recline a seat, and a passenger trying not to laugh at a video on a train. Other entries depict a person surprised to find shoes must be removed at a business dinner and someone who should move some belongings into a backpack.
The roundup also includes a person described as an expert on a very niche subject and a woman replenishing dispensers. Spoon & Tamago credits individual entries to social-media accounts, including @YSSkywalker, @dailyportalz, @ai_okubo0617, @zukitomotomo, @ef510515hokuto3, @iwanttobeJinrui and @08Aikorian.
The publication presents the list as a selection of its favorites from this year’s festivities, not as a complete record of participants or costumes. It points readers to the Japanese hashtag #地味ハロウィン to find more examples on social media.
Everyday Situations Become Costumes
Jimi Halloween gives participants a way to join Halloween celebrations without dressing as witches, zombies or other conventional characters. Its premise is deliberately modest: a costume may represent a recognizable moment from work, travel or dining out, and the audience has to infer the scenario from the details.
That format also shapes the event’s appeal. The costumes in the roundup draw on shared experiences—social awkwardness, small misunderstandings and practical inconveniences—rather than relying on elaborate makeup or fantasy props. Spoon & Tamago’s annual selection makes those otherwise fleeting situations visible as a distinctive form of seasonal humor in Japan.
The examples should be understood as a curated set from the publication. The source does not provide attendance figures, participation totals or evidence that the listed costumes represent the event as a whole.

From Daily Portal Z to 2026
According to Spoon & Tamago, the tradition began in 2014, when a group of adults at Japanese web publication Daily Portal Z wanted to take part in Halloween but felt embarrassed about wearing conspicuous costumes. They chose instead to dress as mundane, everyday people and situations.
Spoon & Tamago says it coined the English phrase “Mundane Halloween” in 2018 and has covered the event since that year. The publication describes the Japanese name as Jimi Halloween; its source also directs readers to the hashtag #地味ハロウィン for posts beyond the roundup. The 2026 article continues that coverage with a new set of examples, while pointing back to previous years’ selections.
““Mundane Halloween, as we coined it back in 2018, is when people dress up in costumes so mundane they have to be explained.””
— Spoon & Tamago
The Roundup’s Scope and Reach
Spoon & Tamago does not report how many people took part in Jimi Halloween in 2026, how many costumes were submitted or how it selected the featured examples beyond calling them some of its favorites. The roundup therefore cannot establish how widely the event was celebrated or whether the listed scenes reflect broader trends.
The article attributes costumes to social-media accounts, but the source material does not provide further interviews with the people pictured or details about where each costume was presented. It also does not give independent confirmation of the event’s history; the origin and coverage timeline here are the publication’s account.
More Costumes Through the Hashtag
Readers looking for additional 2026 entries can search social media for #地味ハロウィン, as Spoon & Tamago recommends. The publication also points to its coverage from earlier years. Its source does not announce a schedule for further reporting or provide details about a next organized event, so whether it will publish another roundup remains unconfirmed.
