Unique Costumes Capturing Everyday 'Aruaru' Moments Gather in Droves

During the 2025 Halloween season, '#JimiHalloween2025' garnered significant attention on social media, trending on X (formerly Twitter). Standing apart from the usual vibrant costumes, this annual event features unique outfits that intricately portray everyday 'aruaru' (common scenarios) or specific situations that everyone has experienced at least once, eliciting empathy and laughter from many users.

This year, related posts began appearing around October 30th, peaking on Halloween day, October 31st. Numerous comments such as "Jimi Halloween is happening! 🤭", "I really love this hashtag," and "The highly anticipated tag is back again this year! ‼️" were observed, indicating its immense popularity.

Brilliant "Situation Reenactment" Costumes Emerge One After Another

What particularly caught the eye among this year's posts was the sharp insight behind them. For instance, Hiroyuki Takagaki's (Colorful Diamond) costume, "The Aunt That Service Industry Workers Fear," and shu's "Person Who Forgot Their Eraser," realistically recreated scenes many have experienced, prompting a resounding "I get it!" from viewers.

Furthermore, the official account of Miso Ramen Denmaru & Ikkokudo posted "The person who feels a little lonely because their 'Gochisousama-deshita' (thank you for the meal) when leaving the restaurant was drowned out by the store's busyness," which highlighted humor unique to ramen shops. Additionally, a costume praised by Akane as "I think this is the winner of Jimi Halloween 2025 🥇" – "This is really a winter pediatrician's office 😂 So much luggage. Mom's hands are full, but she still has to carry this (child) too. That's the set." – resonated deeply with parents and garnered significant support.

Many other costumes that made viewers grin also appeared, such as "The person bracing themselves to call after getting into an accident in their parents' car" and "The person who went to a convenience store in their pajamas late at night and got awkwardly caught up in a town's Halloween event." "Jimi Halloween," which captures momentary situations hidden in daily life rather than character cosplay, has undergone its own unique evolution, leading to comments like "It feels less like a costume and more like just explaining a situation 🤣."

"Jimi Halloween 2025" presented a new way to enjoy Halloween, humorously expressing trivial everyday moments rather than outlandish or flashy ones, bringing smiles to many again this year. Expectations are already rising for what "aruaru" costumes will appear next year.

The context

"Jimi Halloween" (地味ハロウィン), literally translating to "Plain Halloween" or "Subtle Halloween," is a unique Japanese alternative to traditional Halloween celebrations. It was initiated by the Japanese web portal Daily Portal Z. Unlike typical Halloween where people dress up in elaborate, scary, or character-based costumes, Jimi Halloween encourages participants to create outfits that depict mundane, highly specific, and often relatable everyday situations or types of people. The humor of Jimi Halloween comes from the subtle, often awkward, and instantly recognizable scenarios it portrays, eliciting a collective "aruaru!" (あるある) from viewers. "Aruaru" is a Japanese expression that means "that happens a lot," "it's a common occurrence," or "I can totally relate to that." The event has gained significant popularity in Japan for its cleverness and ability to find humor in the ordinary, offering a refreshing contrast to the more flamboyant Western-style Halloween trends.
