Mirumi, a fluffy pink robot with an owlish face and slothlike arms, is the latest in a long line of Japanese social companion robots designed to combat loneliness. However, the author finds Mirumi to be adorably boring, with the robot failing to engage anyone on her commute or at the office. The only one truly enamored with Mirumi is the author's cat, Petey, who becomes obsessed with hunting and destroying the robot. The article explores the limitations of these types of social robots, questioning whether they can truly fulfill our need for genuine connection, especially for those suffering from loneliness and isolation, such as the author's own parents who struggled with dementia.

Why it matters

Social robots like Mirumi are increasingly being developed and marketed as a solution to the growing loneliness epidemic, particularly in aging populations. However, this article suggests that these robots may fall short in providing the type of reciprocal, meaningful companionship that humans crave. The author's personal experiences caring for parents with dementia raise questions about whether these robots can truly improve mental health and well-being for the most vulnerable populations.

The details

Mirumi is a social companion robot created by the Japanese startup Yukai Engineering. It is designed to imitate a shy infant, moving its head to peer curiously at people but ducking away when approached. The author received Mirumi as a review unit and found it to be largely ignored by people on her commute and in the office, save for some initial amusement at its mechanical noises and the sight of plugging a USB-C cable into its 'butt'. The only one truly captivated by Mirumi was the author's cat, Petey, who became obsessed with hunting and destroying the robot, often leaving it decapitated on the floor. The author compares Mirumi to the helper robots depicted in the Broadway show 'Maybe Happy Ending', which explores the loneliness and impending 'death' of discontinued robots, and reflects on whether a robot companion could have provided any comfort to her own parents as they struggled with dementia.

  • The Great East Japan Earthquake happened a few months before the author's 2011 conversation with a robotics professor in Tokyo.
  • Mirumi arrived on the author's doorstep in a box that looked like a shopping bag in late 2025.

What they’re saying

“Though, it's likely that the hunt is what really fueled Petey's desire. (My spouse's theory is that mama's boy Petey was spurred by jealousy.)”

— The author (The Verge)

“I ugly cried, stuffing tissues up my nose so as to not bother other theatergoers with my incessant snot sniffling. Not just because the helper bots are romantics, but because a supporting character looked so much like my dead father.”

— The author (The Verge)

The takeaway

This article raises important questions about the limitations of social companion robots like Mirumi in truly addressing the complex issue of loneliness, particularly for vulnerable populations such as the elderly and those suffering from dementia. While these robots may provide some initial novelty and amusement, the author's personal experiences suggest they may fall short in fostering the genuine, reciprocal connections that humans crave. The article suggests that curing loneliness may require more than just cute, predictable robots, but rather a deeper understanding of the emotional and social needs of those struggling with isolation.
