Cinnamoroll was created by Sanrio on March 6, 2001, so as of February 2026 he is 24 years old in real‑world years.

In the Sanrio universe lore, Cinnamoroll is a magical puppy who was “born” on March 6 on a cloud and stays a tiny puppy rather than visibly aging, which is why he always looks eternally young in merch and animations.
