With his magical gadgets and loyal friendship with Nobita, Doraemon is a symbol of childhood nostalgia. But few know the tragic and touching origin story behind this iconic character — especially the mystery of why he has no ears.
In this blog post, we’ll dive deep into Doraemon’s backstory, explore how he was created, and reveal the emotional reason he lost his ears. Whether you're a long-time fan or new to the world of Doraemon, this article will give you fresh insights into one of anime's most enduring legends.
Who Created Doraemon?
Doraemon was created by the legendary Japanese manga artist duo Fujiko F. Fujio. First published in December 1969, the Doraemon manga quickly gained popularity across Japan and eventually around the world. The series was aimed at children but included moral lessons, futuristic science, and humor that appealed to all age groups.

The central characters include:
Doraemon – the robotic cat from the 22nd century.
Nobita Nobi – a lazy and unlucky boy who receives help from Doraemon.
Shizuka Minamoto – Nobita’s kind and intelligent friend (and future wife).
Takeshi (Gian) and Suneo – Nobita’s bullies-turned-friends.
The Birth of Doraemon: A Robot with a Mission
Doraemon was built in the Matsushiba Robot Factory on September 3, 2112. He was one of many cat-type robots, created to assist humans. Unfortunately, Doraemon was not perfect. Due to a manufacturing error, he was considered a substandard robot, and ended up being sold as a nanny robot to Nobita’s descendant, Sewashi Nobi.
Sewashi, seeing Nobita’s miserable future, sends Doraemon back in time to help his great-great-grandfather live a better life. This act of kindness sets the stage for countless adventures and emotional moments between Doraemon and Nobita.
Why Doraemon Lost His Ears: The Tragic Incident
One of the most frequently asked questions by fans is:
“Why does Doraemon have no ears?”

The Accident That Changed Everything
Originally, Doraemon was designed with a pair of cute, round, yellow ears. However, his life changed forever due to a tragic incident. According to the official story from manga and anime specials:
"Doraemon was bitten on the ears by a robot mouse while he was sleeping."
This unexpected attack by a mechanical mouse damaged his ears beyond repair. Despite attempts to fix them, they could not be restored.
Emotional Breakdown and Blue Tears
The loss of his ears was a traumatic experience for Doraemon. When he saw himself in the mirror and realized his ears were gone, he was devastated.
He cried for days and days. In fact, according to the story, Doraemon cried so much that his original yellow paint washed off, turning him into the blue-colored robot cat we know today.
His sadness and trauma left a permanent mark not just on his appearance, but also on his personality. It’s why Doraemon is extremely afraid of mice — a rare trait for a cat, robotic or not.
Doraemon’s Fear of Mice: A Lasting Phobia
Following the ear-biting incident, Doraemon developed an intense phobia of mice. This is played for laughs in many episodes, where the normally calm and resourceful robot turns into a panicked mess at the sight of a mouse.

This ironic twist — a cat afraid of mice — adds a layer of humanity to Doraemon’s character and helps children understand themes of fear, trauma, and healing in a light-hearted way.
Symbolism Behind Doraemon’s Appearance
Doraemon’s missing ears and blue color are more than just design quirks. They symbolize:
Loss and Recovery – He lost something dear but continued his mission with courage.
Imperfection – Doraemon isn’t perfect, and that’s what makes him relatable.
Emotion in Robotics – Despite being a robot, Doraemon experiences love, fear, sadness, and joy, making him more human than machine.
These traits resonate deeply with fans across generations.
Doraemon’s Evolution Through the Years
Since his debut in 1969, Doraemon has appeared in:
Over 1,300 manga chapters
Several animated TV series
More than 40 full-length feature films
Video games, merchandise, and even space missions (Doraemon was made an official “anime ambassador” by Japan’s Foreign Ministry)
Despite the changes in animation and storytelling over the years, Doraemon’s core story and his missing ears remain central to his identity.
Conclusion: More Than Just a Robot Cat
The story of how Doraemon lost his ears is a moving tale of vulnerability and resilience. It shows us that even a robot can feel pain, face fears, and overcome emotional trauma. Doraemon’s design isn’t just cute — it tells a story of sorrow, strength, and the power of friendship.
