Chindōgu: The Japanese Art of “Unuseless” Inventions

kottke.org November 25, 2025 By Jason Kottke

Chindōgu is the Japanese practice of inventing things that are not exactly useful but neither are they useless; they’re more unuseless, a term coined by chindōgu’s originator Kenji Kawakami. Some examples are tiny umbrellas for shoes, chopsticks with a tiny fan on them to cool your noodles before you slurp them, a flu headset (basically a roll of toilet paper you wear as a hat), and onion chopping glasses that have little fans that blow the onion fumes away from your eyes so you don’t start crying. This video explains chindōgu and provides some examples:

This is a great explainer as well, with lots of images and videos of examples, like this one:

Chindōgu have to be made. If you design the invention on paper and don’t make it, it doesn’t qualify. It’s a piece of paper with a bad invention on it. Bring the invention into the physical world so humankind can experience how truly almost useless it is.
