MaRI is developing human-friendly solutions for snoring suppression.

MaRI Co. Ltd. provides user-friendly snore suppression solutions.

Approximately 30% of the population are snorers but are otherwise healthy.
We provide an innovative approach that solves the problems caused by snoring.

We also solve snoring problems without placing a burden on the snorer.

We have developed an easy-to-use product that suppresses snoring casually.

The equipment is simply placed on the user’s bedside. There is nothing to bother the sleeping user.

About MaRI

Severe snorers are frequently affected by symptoms including sleeplessness, headaches, daytime sleepiness, and fatigue. However, most snorers show no subjective symptoms. This is why we are developing snoring solutions to improve the relationships between couples that are suffering from the effects of snoring.

We provide the most user-friendly and easy-to-use snoring solutions based on accurate and high-quality audio signal processing techniques to help couples suffering from snoring problems without use of invasive techniques.

We focus on the capabilities of each of our engineers and bear in mind that young engineers can participate smoothly in activities at research and development sites.

We are conducting research and development jointly with Tohoku University, Stanford University, and Kyoto University.
