TOP MESSAGE Greetings from the CEO

Since our founding, we have focused on “words,” which have been cherished by humankind, and have created a “tool” to quantify the inner state of mind, envisioning it to start with the creation of a cultural platform for “knowing yourself from your voice.”

In this process, we have been discovering areas untapped by humankind day after day as we explore the “words” more deeply. It is like entering a state of nature where no man has ever set foot.
We grow slowly in harmony with nature, but sometimes nature is destroyed by unforeseeable factors such as disasters. In these cases, we respect each other, support each other to restore ourselves, and repeatedly regain new nature.

We also feel that, by echoing our beautiful voices every day, we can weave a good world through our own growth and by encouraging others to resonate and empathize with us. However, sometimes it is difficult to understand our own inner state of mind, or to create an ecosystem that is immediately recoverable even if we know that someone we care about is in bad shape.

In our modern society, we will keep “unlocking the secret of voice” and grow into the next step to achieve our goals of “creating an ecosystem that can recover people and society with voice” and “creating a culture of beautiful voices.”

We would like to work to spread the “vocal biomarkers” around the world, as we are the only company that can achieve these goals by exploring the Japanese language while feeling its richness and beauty every day. We strongly envision that, when our goals are achieved, we will see a society where beautiful “words” resonate around the world as nature grows. Until then, we will do our best to build a world of peace and mutualism.

CORPORATE PHILOSOPHY Corporate Philosophy

VISION

Resonant Voices,
Spinning Societies

Humankind has developed societies in which people respect each other and support each other through empathy, resonance, and sympathetic vibrations.
PST will create a “more beautiful society” from a new perspective under the key phrase, “Resonant Voices, Spinning Societies.”

MISSION

Unlocking the secrets
of voice

The voices we unconsciously utter every day contain a surprising variety of information. In Japan, people have developed a “culture” of voice to convey their state of mind to other people by means of “voice tones” or “KOTODAMA (spirit of words).”
Vocal biomarkers, the state-of-the-art technology by PST that “unlocks the secrets of voice,” will contribute to people’s health by being used for health management, physical and mental conditioning, disease prevention, and diagnosis and testing.

SLOGAN

Back to Voice

By returning to the “voice” that humankind has cherished since ancient times, and by quantifying and visualizing physical and mental conditions, we will join forces as a company to create an ecosystem that enables the recovery of people and society.
