Over 20 Intellectual Properties: 3D Structured Pillow Prevents 'Hidden Hypoxia' from Tongue Base Collapse During Sleep, Offering an Option for Those with Insomnia, Sleep Apnea, and CPAP Discontinuation.
Toratani Co., Ltd. announced a 3D structured pillow that prevents 'hidden hypoxia' caused by tongue base collapse during sleep. Protected by over 20 intellectual properties, including patents and design registrations, it offers a new option for individuals with sleep apnea and those who have discontinued CPAP.

Toratani Co., Ltd. (Headquarters: Kahoku City, Ishikawa Prefecture; Representative Director: Ikumi Toratani) has newly acquired a design registration for a special structure that physically prevents 'tongue base collapse' (the tongue shrinking into the back of the throat and narrowing the airway), which is considered the main cause of sleep apnea syndrome (SAS). This, combined with existing patents, allows them to introduce a robust 'respiratory infrastructure' pillow to the market, protected by over 20 intellectual property rights. They aim to popularize technology that maintains 'moderate breathing'—neither shallow nor deep—and tackle the modern blind spots of oxygen deficiency and autonomic nervous system imbalance during sleep.
■ Development Background: Why are humans the only ones who snore and experience apnea?
As a trade-off for evolving to speak, humans developed an unstable throat structure, leading to the fateful problem of 'tongue base collapse,' where the tongue collapses into the throat due to gravity during muscle relaxation in sleep. While CPAP is a common solution for tongue base collapse, many people discontinue it due to various stresses during sleep, such as headbands, forced airway expansion by air pressure, mask displacement, throat discomfort, inadequate carbon dioxide expulsion, and other factors that disrupt sleep.
Toratani believes that while many sleep improvement approaches focus on 'soft aspects' like brainwaves and sleep environment, the 'physical infrastructure' problem of airway obstruction is an urgent issue that should be solved by bedding structure, and they have researched this. By eliminating sleep-disordered breathing and promoting parasympathetic dominance, the basic life functions of oxygen intake and autonomic nervous system balance are restored.
■ Intellectual Property Proves the 'Precision Machine for Protecting Respiration' with 3 Core Aspects
1. Anatomical Approach: Blocking 'Tongue Base Collapse' with Patented Technology
Against muscles that relax during sleep, the pillow provides appropriate positional feedback to the brain through skeletal support. Instead of compressing the neck, it precisely supports the base of the head (superior nuchal line), changing the center of gravity and physically preventing 'buckling' where the airway bends.
2. Apparel-Inspired 3D Stereoscopic Structure: Multi-faceted Support through Design Registration
The 'theory' of the patent has been translated into a 'form' that anyone can use daily. It maintains an angle that easily secures the airway in all moments—supine, side-lying, and turning over. Furthermore, it physically and stably prevents tongue base collapse, supporting 'moderate breathing' through a familiar means like a pillow, even for those who have given up on CPAP or are resistant to mouthpieces.
3. Physiological Impact: 'Metabolism During Sleep' Supporting Healthy Lifespan
Hypoxia due to hypopnea inhibits cellular energy metabolism, leading to autonomic nervous system imbalance and frailty. This product supports the extension of a healthy lifespan from a structural perspective by stabilizing oxygen supply and aiding mitochondrial activity.
