Good morning.
Today is September 3rd, which means it’s Doraemon’s birthday!

Doraemon, one of Japan’s most beloved and iconic characters, was actually born on September 3rd, 2112 — a robot from the future! Did you know that?

Every year on this day, fans celebrate “Doraemon’s Birthday,” and special episodes often air on television. In this article, we’ll explore the origin of Doraemon’s birthday, along with touching backstories, trivia, and heartfelt episodes that make him so lovable.

🎂 When is Doraemon’s Birthday, and Why September 3rd?

According to the official setting, Doraemon was “born” on September 3rd, 2112. This futuristic cat-type robot traveled back in time from the 22nd century to help save Nobita’s future.

In 2012, marking 100 years before his birth, events were held across Japan to celebrate the occasion.

📦 Put in the Bargain Bin After Birth!? A Bittersweet Origin Story

🤖 A Robot Born with Hope… and Rejection

Doraemon was created on September 3rd, 2112 in a robot manufacturing plant in the 22nd century.

He was supposed to be a cutting-edge “nanny robot,” designed to assist families. But due to various defects—poor balance, lack of direction sense, and slow response—he was deemed “unfit” for service.

Despite being brand-new, Doraemon was placed in a bargain bin, treated like a product no one wanted.

His expression, resting in the corner of the factory, looked vacant—as if he hadn’t even been switched on.

💤 A Long Sleep in the Discount Bin

After that, he remained unsold for a long time, simply displayed as a “cheap robot.”

Eventually, Sewashi, the great-great-grandson of Nobita, bought him for his family. That was likely around 2114, meaning Doraemon spent two years untouched, simply waiting as an “unsold product.”

For a robot with a heart, this was undoubtedly a lonely, silent time.

👦 The Turning Point: Meeting Sewashi

Once Doraemon was taken in by Sewashi’s family, he was finally activated.

He was then sent to Nobita’s time—a mission that marked the moment he found his purpose. Once considered defective, Doraemon took on a grand new role: to help someone in need and change the future.

It’s as if being “rejected” gave him the power to “save.”

💡 A Deeper Message Behind His Birth

Doraemon’s origin is more than just sci-fi. It holds a meaningful message:

“Even if you’re imperfect, being needed by someone makes you complete.”

Though now a national icon, Doraemon began as a “rejected robot.”
Perhaps that’s why he never gives up on Nobita—because he knows what it feels like to be unwanted.

🍡 Favorite & Feared: The Sweet and Sad Stories Behind Dorayaki and Mice

🍡 [Favorite] Dorayaki — A Taste of Friendship and Warmth

Doraemon’s absolute favorite treat is dorayaki.
He’s often seen secretly munching on them from his pouch.

But why dorayaki?

This traces back to a robot named Noramyako, a dance-type cat robot from the future. She once gently handed Doraemon a dorayaki and said, “Here, for you.” That small act of kindness deeply moved him.

From that moment, dorayaki became more than just a sweet—it became a symbol of care and being valued.

Interestingly, Doraemon refuses to eat dorayaki shaped like mice or with mouse stamps—linking to his greatest fear…

🐭 [Fear] Mice — The Trauma Behind His Greatest Weakness

Doraemon’s fear of mice is no joke—it’s his biggest weakness.

Back in the 22nd century, while napping, a mouse chewed off his ears. This traumatic event led to his ears being lost, and during repairs, a mistake turned him blue.

The incident was so distressing that Doraemon even became depressed and stopped smiling for a time.

So when he sees a mouse, his exaggerated reactions are actually deep emotional scars beneath the comedy.

This contrast between his love of dorayaki and fear of mice highlights his deeply human-like personality.

🧁 Small Treat, Big Drama

Doraemon’s “favorites” and “fears” aren’t random—they each have a story, adding depth and humanity to his character.

Behind his cheerful face are bittersweet memories.
And yet, he continues to help Nobita with unwavering kindness.

📺 Doraemon Was Animated Three Times! An Icon Through the Decades

• 1973: First anime (NTV) – Short-lived
• 1979: Reboot (TV Asahi) – Huge success
• 2005: Full renewal with new staff & cast – still ongoing

Since 2019, it airs on Saturdays at 5 PM.

🧠 How Old Is Doraemon? The Mystery of His Real Age

Doraemon was born in 2112, and when he came to Nobita’s time, fans wondered: How old is he?

Sewashi was in 4th grade in 2124, meaning Doraemon was 12 years old on record.
But considering he was left inactive for 2 years, some fans believe his actual (active) age is closer to 10.

This kind of speculation keeps fans fascinated even decades later.

🌈 Conclusion: Remembering a Kinder Future on Doraemon’s Birthday

September 3rd, the birthday of a robot born in the year 2112.

He spent his early years unwanted, sleeping in a discount box.
But he was eventually activated and sent back in time to help Nobita—and has saved him (and us) countless times since.

Smiling while munching dorayaki, screaming at mice—Doraemon is not just a machine.
He’s a being who overcame trauma and found purpose through helping others.

He is, in every sense, a symbol of hope.

💬 A Message from Doraemon

Doraemon’s birthday is more than a celebration of a character.
It’s a reminder that:

“Even if you’re imperfect, kindness and courage can shape the future.”

This September 3rd, watch Doraemon with your children, eat dorayaki together, and ask:

“What kind of future do you want to create?”

Just like Doraemon stood by Nobita,
perhaps someone—visible or not—is quietly standing by you too.
