If you\u2019ve checked social media today, you may have stumbled across a see-through ballpoint pen with real parasites swimming around inside it (and maybe dismissed it as AI slop). Prompting grossed-out reactions and comparisons to Resident Evil, the pen is actually a real souvenir from Japan\u2019s Kochi Prefecture.<\/p>\n<\/p>\n

Earlier this year, Japan\u2019s Asahi News<\/u><\/a> fished out the origins of this strange writing implement. Even though the pen looks like something you\u2019d find on Wesker\u2019s desk, it\u2019s a real product purchasable from a fishmongers\u2019 shop in Susaki city, Kochi Prefecture. The transparent section of the pen contains living Anisakis, a type of fish-dwelling parasite, suspended in a clear liquid. The parasite can cause food poisoning if you eat raw or uncooked fish containing it. Lovely.<\/p>\n

The company behind the pen is not Umbrella Corporation but local company Tada Suisan. According to company president Takuhiro Tada, the inspiration came from an acquaintance on social media back in 2021 who \u201cwas putting Anisakis extracted from his own stomach into ballpoint pens.\u201d In his original video post<\/u><\/a>, pen creator FUNA84 quipped that, \u201cIf you use it when signing the consent form for Anisakis extraction surgery at the hospital, you can show them you\u2019re an Anisakis master!\u201d<\/p>\n

Inspired by FUNA84\u2019s post, Tada tried making an Anisakis pen for fun but \u201cit got such a big reaction, that I decided to sell them at the store.\u201d<\/p>\n

The Anisakis are extracted from caught fish (specifically skipjack\/bonito), and so the number of pens made by the company each week depends on the catch. \u201cSometimes we make about 20 pens a day, while at other times we might not make any for a week,\u201d Tada explained. <\/p>\n

The pens have previously created waves on Japanese news and social media back in 2024 but this time, they have caught the attention of users outside Japan \u2014 especially players of a certain Capcom survival horror series. Resident Evil fans have been quipping<\/u><\/a> that it’s an \u201cUmbrella Corporation 5-year work anniversary present.\u201d Even Resident Evil\u2019s Community and Social Media Manager for Europe noted that the pen sounds like something that would pop up in an ominous in-game diary entry\u2026<\/p>\n

I found this cool pen with wriggly stuff in it at the office, but as my manager walked in I started chewing nervously on it. I also let my dog have a nibble because it tasted funny. Hope the thing inside doesn’t escape.<\/p>\n

Posting on April 8, Tada himself reacted<\/u><\/a> to the pens going viral, saying that he understood why the product was causing a stir but noted that the content had been shared by unauthorized reposter accounts. He also mentioned that there have been some threatening comments.<\/p>\n

The Anisakis pens have also stirred up ethical debates<\/u><\/a> online, with some suggesting that they are pointless cruelty to living things. It certainly looks like the kind of pen Umbrella scientists would have used when taking notes on the latest mutant experiment. <\/p>\n
