AMAGAMI HAM HAM - Experience Soothing Play-Bites Anytime

There’s a specific moment of tenderness that babies and young animals share—those gentle, playful “nibbles” on your finger that feel soothing, affectionate, and strangely comforting. They last only a short time in real life, but now, thanks to Yukai Engineering, you can experience that calming sensation any time you want with the AMAGAMI HAM HAM, the world’s first relaxation robot designed to mimic natural play-biting behavior.

The AMAGAMI HAM HAM uses an innovative motion system called the HAMling system, combined with Yukai’s proprietary Hamgorithm, to deliver a wide range of nibbling sensations. Sometimes it’s soft and slow, other times quick and playful—each “bite” is unique, bringing a delightful, comforting unpredictability that makes the interaction feel alive. As soon as you insert your finger, embedded sensors recognize the touch and activate the gentle jaw motions, giving you a soothing tactile experience that melts away stress and tension.

Each AMAGAMI HAM HAM character—whether it’s Yuzu the Calico Cat, Kotaro the Shiba Inu, Rinrin the Panda, Kururi the Otter, or Marron the Bear—is crafted from soft, premium plush materials with subtle variations in facial expression and body shape. Inside, a flexible resin jaw structure delivers the perfect balance of firmness and softness, ensuring every nibble feels pleasantly realistic without ever being uncomfortable.

Setup is incredibly simple. Just unzip the back, insert three AA batteries, flip the switch, and your HAM HAM is ready to nibble. It operates quietly (with only a faint motor sound), requires no complicated maintenance, and can be enjoyed at home, at your desk, or during breaks for quick and soothing stress relief.

Inspired by real caregiving moments and developed by engineers dedicated to emotional well-being, the AMAGAMI HAM HAM brings a unique form of comfort that blends robotics, plush design, and human nostalgia. Whether you’re seeking relaxation, sensory satisfaction, or simply a cute companion to brighten your day, this play-biting robot is ready to deliver a heart-warming experience again and again.
