Company Profile

Our mission

We want to solve the world’s snoring problems gently

MaRI was established to solve problems caused by lack of sleep by providing user-friendly solutions
that solve sleep problems caused by factors such as snoring and stress.
Snoring reduces the quality of sleep and can cause high blood pressure and sleep debt.
Sleep debt can lead to a decline in intellectual productivity and accidents,
including accidents while driving, caused by falling asleep and lack of attentiveness.
In addition, many people are dissatisfied with their poor quality or lack of sleep due to their partner’s snoring.
In the United States, the situation is so severe that snoring is currently ranked as the number three cause of divorce.
For snorers, we prevent diseases by normalizing their SpO2 levels. For their bed partners,
we provide comfortable sleep while also improving their partner’s health.
Our mission is to maintain and improve marital relationships (Marital Relationship Improvement).
