What Is Mirumi? Know All About Mirumi Doll And Why It Is Internet’s New Obsession

After Labubu dolls dominated timelines in 2025, the internet has found a fresh obsession-Mirumi, a tiny, hyper-realistic charm robot that's winning hearts across social media.

Designed by Tokyo-based Yukai Engineering, Mirumi isn't just another collectible toy. It's a miniature companion robot created to spark small, joyful moments in everyday life. With its soft fur and shy expressions, Mirumi behaves more like a curious baby than a static plush, quietly observing the world and reacting when it senses movement, sound, or touch.

What exactly is Mirumi?

According to its creators, Mirumi is meant to recreate the warm feeling you get when a baby unexpectedly looks at you in a crowded place. The little robot turns its head to peek around, tilts shyly when noticed, and makes gentle movements that feel surprisingly lifelike. Yukai Engineering CEO Shunsuke says Mirumi was built to express emotion through subtle gestures, creating moments of shared delight not just for its owner, but for anyone who notices it.

How much does Mirumi cost?

Mirumi doesn't come cheap. Available in grey, pink, and ivory fur, the charm robot is currently priced at 18,360 yen (around Rs 10,500) during its promotional phase. Once the crowdfunding window closes, the price rises to 21,803 yen (approximately Rs 12,500)-still lower than its expected retail price of about $150.

Where did the idea come from?

The concept for Mirumi emerged during Yukai Engineering's internal Make-a-Thon in 2024. A team of engineers and designers pitched the idea of creating a small, robotic, "yokai"-inspired creature-part supernatural, part human-imbued with the innocence and behaviour of a baby. That experimental idea soon evolved into Mirumi.

Why is Mirumi so special?

What sets Mirumi apart is how alive it feels. Using a combination of sensors and a custom algorithm, the robot responds naturally to its surroundings. It nods, shakes its head, glances around, and even shows hesitation or bashfulness. With dozens of subtly randomised movement patterns, Mirumi avoids repeating the same gestures, making each interaction feel spontaneous.

Even its battery behaviour is expressive. When power runs low, Mirumi's movements slow down. When unplugged, it turns away slightly, and once fully charged, it gives a small nod-as if to say it's ready again.

Designed for both charm and practicality, Mirumi can cling securely to bag straps with its tiny arms, while its plush exterior-made in Japan-adds to its soft, comforting appeal. Rounded, baby-like, and undeniably cute, Mirumi looks less like a toy meant for display and more like a companion meant to go everywhere with you.

In a world crowded with gadgets and collectibles, Mirumi stands out by doing something simple yet powerful-making people smile, one shy glance at a time.
