The Ten Tenets of Chindogu

Ten rules defining the Japanese art of creating "unuseless" inventions—objects that appear to solve problems but are too absurd for actual use.

  1. A Chindogu cannot be for real use.

    If you can actually use it without embarrassment, it’s not a Chindogu. The invention must be almost but not quite practical.

  2. A Chindogu must exist.

    You can’t just imagine a Chindogu—it must be physically made. The act of creation is essential.

  3. Inherent in every Chindogu is the spirit of anarchy.

    Chindogu challenge the assumption that everything must be useful. They question the relentless drive for efficiency.

  4. Chindogu are tools for everyday life.

    They address real, mundane problems. The absurdity comes from the solution, not the problem itself.

  5. Chindogu are not for sale.

    Commercialising a Chindogu defeats its purpose. They exist outside the market economy.

  6. Humour must not be the sole reason for creating Chindogu.

    They may be funny, but they’re not jokes. There must be a genuine attempt to solve a problem, however misguided.

  7. Chindogu are not propaganda.

    They cannot carry political or social messages. Chindogu are innocent of ideology.

  8. Chindogu are never taboo.

    They must be acceptable to everyone. Nothing offensive or inappropriate qualifies.

  9. Chindogu cannot be patented.

    They belong to the world. Intellectual property claims contradict the spirit of Chindogu.

  10. Chindogu are without prejudice.

    They must be usable by anyone regardless of age, gender, or background. No discrimination.
