Yokaizen Science

Real-time biometrics. Culturally tuned psychology. Proactive support.

The Yokaizen Ring senses patterns (HRV, temperature, motion). Our models learn your baseline and gently cue the right micro-practice at the right moment—always as a wellness aid, never a diagnosis.

How it works

1
Sensors (Ring)
HRV featuresTemperatureMotion

Photoplethysmography for HRV-related features, skin temperature, and micro-movement (actigraphy). Personalized baselines adapt over time.

2
Mood Inference
Baseline learningContext awareness

Multi-signal fusion detects shifts in arousal/regulation; context & routines refine precision. Designed for anticipatory cues—not labels.

3
Proactive Cue
Just-in-timeMicro-interventions

When patterns suggest strain, your Yokai nudges a 30–90s micro-practice (breath, focus, reframe) or a supportive message.

Wellness guidance only. Not intended to diagnose, treat, cure, or prevent any disease.

Why proactive works

Earlier than awareness

Physiological triggers can shorten anxiety episodes when support is delivered before escalation.

Personal & timely

Personalized, just-in-time digital supports increase engagement versus generic content.

Always available

24/7 access creates a safety net that reduces crisis episodes in at-risk youth.

Our therapeutic approach

We blend CBT/SEL micro-skills with Japan-native methods (Morita's action-orientation, Naikan reflection). Delivering skills through character companions increases disclosure and everyday practice.

CBT & SEL micro-practices: breathe, focus, reframe, act.

Morita & Naikan principles for culturally resonant habits.

Manga-style companions foster safer self-expression.

Evidence & pilots

Multi-sensor mood detection
Review studies

Literature supports combining autonomic signals (e.g., HRV) with temperature/motion; per-user baselines are essential.

Physiology-triggered help
Timing matters

Automated, just-in-time supports outperform self-initiated ones in reducing episode duration/intensity.

Character companions
Engagement

Manga-style AI guides increase emotional disclosure and engagement among Japanese adolescents.

Early pilot signals
Pilot data

Beta pilots indicate shorter anxiety episodes with ring-prompted grounding and improved self-regulation over 3 months.

Safety, ethics & privacy

Wellness product: does not diagnose/treat medical conditions.

Consent-first: clear opt-in, pause anytime.

Data minimization & end-to-end encryption; user control over deletion/export.

Transparent models; we avoid sensitive inferences and share limitations.
