ONY logo

Ony, often written in capitals as ONY, is a recurring placeholder brand for Sony in most of Gosho Aoyama's works. Usually Ony is the standard brand for televisions and cell phones in Aoyama's series.

The name originally comes from Yaiba and was a play on words with Sony and "Oni", since the products were created under the possessed Takeshi Onimaru's reign over Japan, during which he and his minions created some "demonized" versions of real companies and brands. First appearances of ONY products in different Manga often appear in conjunction with other Yaiba allusions.


As far as can be gathered from the works of Gosho Aoyama, ONY produces:

  • Television sets (tube, flat screen and pocket TVs)
  • Monitors for aircraft
  • Microwaves
  • Mobile phones (such as the smartphone "Xperikan")
  • Cassette tapes and recorders
  • Monitoring and surveillance systems
