Detailed Information
Starting Thursday, April 23, 2026, Tsutaya Books, Tsutaya Electrics (excluding some stores), and the Tsutaya Books Online Store nationwide will hold a pre-sale for 'mirumi', a 'glancing' charm robot developed by Yukai Engineering Inc.
*Pre-sale Exhibition Period: Thursday, April 23, 2026 - Thursday, April 30, 2026
Motivated by baby gestures that captivate the world
Suddenly looking up at a sound, looking around restlessly. Staring intently at something, and sometimes turning away whimsically.
'mirumi' is a charm robot that 'glances', themed around the gestures of a baby.
Its presence, gently directing its gaze from near your bag, creates a small emotion in the space just by being there. It caused a massive stir in international crowdfunding, attracting attention from overseas celebrities, designers, and media. Receiving an offer from a brand, mirumi even appeared at Fashion Week in Milan, and is now making its debut in Japan. Please experience the momentary sensation of your eyes meeting in person.
Dedication to Design and Technology
We aimed for an existence that gently touches your heart with small movements, like staring intently with upturned eyes at unexpected moments.
Behavior
Just staring, burying its face in surprise at a loud noise, rubbing its face against a hand, nodding slowly—to realize these gestures, we designed dozens of movement patterns.
Furthermore, by finely adjusting the pacing and timing of movements and combining them with sensing via a microphone and touch sensor, it achieves natural, lifelike behaviors that are whimsical yet seem like a small creature. It shows interest by moving its neck toward sounds or voices, and reacts when petted.
Hugging Mechanism
To achieve both softer, more creature-like movements and the durability to not fall off when attached to a bag and carried around, we went through repeated prototyping and refinement to develop the arm mechanism. We have realized mirumi's unique hugging mechanism, combining strength and cuteness that cannot be expressed with existing mechanisms.
Materials
We pursued a fluffy, soft texture that makes you want to pet it. We use originally produced faux fur fabric from a domestic manufacturer, carefully selecting the color, length, and hair density.
