Japan's bizarre and useless inventions

Japan is famous for innovating and creating many things that we use in our lives, but it also creates many useless and bizarre inventions. There is even a word for these useless inventions which is Chindogu (珍道具), which literally means “unusual tool”. 

Chindogu they are inventions made to solve a particle problem, but which sometimes causes so many other problems, or causes social embarrassment, which in fact has no use.


The term Chindogu was coined by  Kenji Kawakami, an inventor and editor of the Japanese magazine “Mail Order Life.” Together with Dan Papia a book was created that became popular worldwide, known as "101 useless Japanese inventions" or “101 Unuseless Japanese Inventions”. 

Thousands of copies are sold, and every year countless crazy inventions are created and posted on the website chindogu.com or some book or online media, even in record books.

There are 3 fundamental principles for creating a Chindogu:

  1. The invention must exist, even if it is absurd;
  2. It must be kept in the public domain without patents;
  3. It must not be created just for humor, it must be an invention with a purpose;
