Hangyodon is one of the lesser-known Sanrio characters, and his birthday is March 14th! He’s an adorable half-fish, half-human creature with many friends and hobbies! Let’s deep dive into his history with his celebration on the horizon!

The Origin of Hangyodon

Sanrio staff member Hisato Inoue created him in 1985, using his distinct facial features as inspiration. Referencing his large eyes and full lips for Hangyodon’s design, the adorable character’s primary color palette is light blue and yellow!

Hangyodon’s origin story started in the 1980s when Sanrio wanted to create a new character for their brand. The team in charge of the project wanted to come up with something fun, playful, and adorable–and that’s what they did!

He is a blue, fish-like creature with a long tail and tiny, stubby arms. He has big, expressive eyes and a toothy grin that will surely make you smile. His name comes from the Japanese words hangyo and don, meaning “half-fish” and an honorific suffix, respectively

Hangyodon’s birthday is on March 14th, also known as “White Day” in Japan. White Day is when men give gifts to the women in their lives to reciprocate the gifts they received on Valentine’s Day. It’s a fitting birthday for Hangyodon, who loves to spread joy and happiness to everyone he meets.

As for his personality, he’s known for being cheeky and playful. He loves to play pranks on his friends, but he’s never mean-spirited about it. He’s also incredibly loyal and always stands up for his loved ones.
