Is a humanoid robot named 'cinnamon' really working in Japan's nursing homes?

Yes. Donut Robotics and Charm Care have tested cinnamon since July and plan to expand its role to answering nurse calls.

Yes. Japanese startup donut robotics and nursing-home operator Charm Care signed a ¥300 million alliance and have tested a humanoid named “cinnamon” since July, with nurse-call responses next. Japan’s aging population and care-worker shortage make repetitive tasks a clear robotics use case.

The responsible test is whether residents feel comfortable, calls are handled reliably, privacy is protected, and staff workload improves. Robots should support—not replace—the human judgment and empathy at the center of care.

Why nursing homes are testing robots like cinnamon

Care work mixes skilled, personal help with many small, repetitive jobs — answering calls, fetching, reminding, and guiding. With fewer care workers and more older residents, even a robot that handles simple requests reliably can free staff for the human parts of the job. The test is not whether the robot looks human, but whether residents trust it and staff genuinely save time.

What to do, step by step

1. Ask what tasks the robot actually handles today, separate from planned features.
2. Watch how residents respond — comfort and calm matter more than novelty.
3. Check how calls and personal information are recorded, stored, and shared.
4. Confirm a person can always take over quickly if the robot gets confused.
5. Judge success by staff time saved and resident wellbeing, not by headlines.
