A Japanese ballpoint pen containing live parasitic worms is circulating widely on social media, drawing significant online attention. The unique design, featuring Anisakis parasites, has resurfaced in videos, sparking renewed public discussion.

The pen was created a few years ago by a hobbyist in the rural Kochi Prefecture. It contains live Anisakis parasitic worms suspended in herbarium oil, observed moving within the pen.
Anisakis is a genus of parasitic nematodes commonly found in various fish species. If raw or undercooked infected fish is consumed, these parasites can enter the human body and potentially cause anisakiasis.
The pens were reportedly available for purchase at the Michinoeki Susaki fresh fish store. Their re-emergence online has led to widespread reactions.
Many social media users have described the concept as bizarre, some questioned its legality, and others expressed reluctance to use such a pen or questioned the rationale behind its creation.
A post about the pen, shared on X by the handle ‘dom_lucre’, garnered more than 459,000 views. The post described Anisakis as a Japanese handicraft item with a real parasitic worm that moves while writing.
