Japan's Jimi 'Mundane' Halloween Costumes of 2026
Happy Jimi Halloween to everyone who celebrates. It’s that wonderful time of year when our favorite Japanese festival, Jimi Halloween, is on full display. Mundane Halloween, as we coined it back in 2018, is when people dress up in costumes so mundane they have to be explained.
The tradition was started in 2014 by a group of adults at Daily Portal Z who kind of wanted to participate in the festivities of Halloween, but were too embarrassed to go all out in witch or zombie costumes. So instead of the flashy and flamboyant costumes they had been seeing gain popularity in Japan, they decided to dress up in mundane, everyday costumes.
You can comb through social media using the hashtag #地味ハロウィン but below we present to you some of our favorites from this year’s festivities. We’ve been covering this event since 2018 so you can also take a look at some past years too!
