Product Description
At its centre is a non-invasive transcutaneous auricular vagus nerve stimulation device—known as taVNS—which delivers gentle electrical stimulation through an earpiece positioned against the skin of the ear.
Unlike standalone vagus nerve stimulators, yōjō combines the physical device with a personalised digital platform, real-time biofeedback, guided nervous-system activities, health education and access to human coaching.
The result is a practical daily programme designed to help you build a stronger, more flexible nervous system rather than relying on an occasional quick fix.
The sympathetic nervous system prepares you for action and is commonly associated with the “fight-or-flight” response. The parasympathetic nervous system supports rest, digestion, repair and recovery.
Modern life can leave the stress response switched on for longer than necessary. Over time, this may contribute to feeling tense, overstimulated, exhausted, unable to switch off or “wired but tired.”
The vagus nerve is one of the main pathways through which the parasympathetic nervous system helps bring the body back towards a calmer state.
This is known as transcutaneous auricular vagus nerve stimulation, or taVNS.
The stimulation is non-invasive and does not require surgery, needles or stimulation through the neck. The yōjō earpiece is designed to sit securely in the ear, allowing you to complete a session hands-free.
Regular use is intended to support parasympathetic activity and nervous-system flexibility—the ability to respond appropriately to stress and then return to a state of rest and recovery.
yōjō combines this stimulation with personalised activities, education, habit-building tools and biofeedback so that you can understand your nervous system and track how it responds over time.
Daily vagus nerve stimulation may help activate the body’s natural calming response, supporting a greater sense of steadiness and making it easier to move out of stress mode.
yōjō also provides guided breathing, mindfulness and nervous-system activities that can be used between stimulation sessions when you need additional support.
By encouraging parasympathetic activity, yōjō may help prepare the body for rest, reduce pre-bedtime tension and support the transition into sleep.
The platform can also provide sleep-related education, relaxation practices, breathing techniques and personalised activities to help improve the habits surrounding your sleep.
yōjō does not currently function as a conventional sleep tracker. Instead, it monitors nervous-system metrics related to stress, recovery and autonomic balance.
By supporting better recovery and nervous-system regulation, yōjō may help you experience more stable energy throughout the day and reduce the feeling of being simultaneously tired and overstimulated.
yōjō is designed to support the body’s recovery response following exercise, demanding work, emotional stress or periods of poor sleep.
This may be particularly valuable for people who train regularly, work in high-pressure environments or struggle to feel fully recovered between demanding days.
Regular stimulation, combined with yōjō’s guided activities and health education, may help users feel calmer, clearer and less reactive during everyday life.
yōjō is not a treatment for anxiety, depression or any other mental-health condition and should not replace professional medical or psychological care.
By supporting relaxation, parasympathetic activity and nervous-system balance, yōjō may help reduce the stress and tension that can amplify day-to-day discomfort.
It is not intended to diagnose or treat chronic pain, migraines, fibromyalgia or any other medical condition.
Used consistently, yōjō is designed to help improve this flexibility, so your body can move more efficiently between activity, stress, relaxation and recovery.
Your programme may focus on areas such as:
The technology analyses subtle changes in skin colour and tiny movements associated with blood flow and each heartbeat.
From these readings, the yōjō platform can provide information and estimates relating to:
The measurements are intended for general wellness and biofeedback purposes. They should not be treated as clinical measurements or used to diagnose a health condition.
The yōjō care team can help you:
The yōjō platform is designed to help turn vagus nerve stimulation into a regular daily ritual by tracking use, encouraging healthy habits and adapting the programme around your progress.
The scan takes approximately 30 seconds.
The gel helps provide reliable contact between the electrode and the skin.
The app will search for your device and guide you through the session.
The sensation should remain comfortable. A stronger intensity does not necessarily mean better results.
Reduce the intensity if the stimulation feels unpleasant. Stop using the device if you experience burning, persistent itching, pain or significant discomfort.
You can use the time to relax, read, work quietly or prepare for sleep.
The manufacturer’s current guidance is:
A complete charge takes approximately three hours.
Actual battery performance can vary according to device age, intensity settings and usage.
The first two months of platform membership are free as part of the initial twelve-month package.
After the initial twelve months, the platform subscription automatically renews at the manufacturer’s current rate of:
Access to coaching, personalised programmes, app-based biofeedback, educational content and other membership features may end when the paid subscription period finishes.
Subscription prices and available payment options are controlled by yōjō and may change following appropriate notice.
Do not use the device without medical approval if you have an active implanted electronic or medical device, including:
Possible temporary side effects associated with non-invasive vagus nerve stimulation may include:
Only the registered user should use the device. Although another person using the physical device may not necessarily damage it, sharing it can interfere with the accuracy of personalised readings, progress tracking and platform recommendations.
It is not a medical device and is not intended to diagnose, treat, cure or prevent any disease, disorder or medical condition.
It should not replace medication, medical advice, psychological support, physiotherapy or any treatment recommended by a qualified healthcare professional.
Face-scan readings and other information provided by the yōjō platform are for wellness, education and biofeedback purposes only. They should not be used to diagnose a health condition or make medical decisions.
Always consult an appropriate healthcare professional if you have a diagnosed condition, unexplained symptoms or concerns about whether vagus nerve stimulation is suitable for you.
