Company Overview – Evixar Inc.

Atsushi TAKIGAWA
President & CEO, Evixar

Evixar is a deep-tech engineering company specializing in acoustic signal processing — audio watermarking, acoustic fingerprinting, and acoustic communication. Since our founding in 2004, we have built proprietary algorithms and deployed them across three core domains:

• HELLO! MOVIE — Japan's de facto standard for cinema accessibility, delivering synchronized audio descriptions and captions via smartphone with no venue infrastructure required
• AiryMedia — A sound-triggered media platform that turns any audio environment — theaters, stadiums, stores, broadcasts — into an interactive channel reachable from a smartphone
• EAF - Evixar Audio Forensics／SIGNED SOUND — Content authentication technology using audio watermarking and fingerprinting to verify the provenance of audio and video, now available as a commercial third-party certification service.

Our mission is to build infrastructure that connects through sound, and protects through sound.

Magnitude of Algorithm Innovation

Evixar's acoustic communication technology offers a next-generation interface - connecting to services in just 0.1 seconds, and to the world in 0.5 seconds.
With Evixar Audio Forensics (EAF), a system that verifies the authenticity of AI-generated audio, we are building a new kind of social infrastructure: one that "connects through sound, and protects through sound."

HELLO! MOVIE – The De Facto Standard in the Japanese Theatrical Market –

In 2015, the PoC (Proof of Concept) project to study the ideal viewing environment for audiences with low vision or hearing impairment at the movie theatres was launched. The PoC was funded and conducted by various Japanese government ministries (the Ministry of Economy, Trade and Industry among others) along with the major theatrical distributors.

In the study, the following technical requirements were identified:
– The app must work properly in any movie theatre environment across the nation "as is" (meaning with no investment of any additional infrastructure, equipment, staffing, etc.)
– The system must work with consumer smartphones.
– The app must be user-friendly.
– The app must function properly when the smartphones are in airplane mode, with all signal transmissions disabled (not capable to receive calls or text messages)

The parties involved in the study found that Evixar's technology (acoustic synchronization system) met their published criteria and in 2020, the commercial use of Evixar's app HELLO! MOVIE began. The app has become the only solution of its kind in the country and is now the de facto standard for accessibility solutions.
Today, all major film distributors in Japan (Shochiku, Toho, Toei and Kadokawa) as well as the nation's trade associations, such as MPAJ (equivalent of MPAA) and NATO-JAPAN have adopted Evixar's "HELLO! MOVIE" app (coupled with special caption projection glasses) as their official accessibility solution for low-vision and hearing-impaired audiences. 

Warner Bros. and Sony Pictures have used Evixar's system for titles distributed in Japan for several years. Since 2024, Disney and Sony Pictures are using it for major Hollywood titles as well.
We are now bringing "HELLO! MOVIE" to the global market as the new standard for visual and hearing accessibility. In July 2026, HELLO! MOVIE is presenting at the ICTA 2026 Summer Convention in Milwaukee, Wisconsin, introducing our BYOD approach to the international cinema industry.

EAF - Evixar Audio Forensics／SIGNED SOUND

Evixar has developed a content protection service called EAF (Evixar Audio Forensics) that uses a special sound embedded with encrypted data (watermark sound) and fingerprinting technology for sound sources stored in a database.

This helps prevent the misuse of AI-generated deepfake videos. Developing technology that can identify deepfakes and establishing international rules for verifying the safety of new services are major topics on the agenda of the Group of Seven (G7). Evixar works closely with the Japanese government to strengthen content protection, and has been selected for the Ministry of Internal Affairs and Communications' "Development and Demonstration Project for Countermeasure Technologies against Online Disinformation" for three consecutive fiscal years (FY2024–FY2026). 

In July 2026, Evixar and Shachihata Inc. — Japan's leading trust and seal brand — jointly launched SIGNED SOUND, a commercial third-party certification service for audio and video content. SIGNED SOUND embeds C2PA-compliant authentication information into audio signals, enabling reliable verification of media origin even after content has been distributed across digital platforms.

AiryMedia - Create a Whole New Media on top of Invisible Sound -

Acoustic-Linked Light Stick

This next-generation light stick controls its color and illumination through sound, eliminating the need for radio waves.
No complicated setup is required; simply play music as usual to achieve stunning light effects.
As it responds to sound, this sound-responsive cheering item works with live streams, recordings, and Blu-ray playback.

Cheer Screening in Movie Theater
In Japan, cheer screenings "Ouen Joei" are fan events that encourage audience participation often through cheering, singing, clapping and bringing other common concert items like light sticks into the theater. It's an opportunity to connect with fellow fans while experiencing a movie in a concert-like setting.

Evixar's Acoustic-Linked Light Stick is programmed to react to the film's audio, automatically changing colors to match each moment. There's nothing to configure, simply turn it on and enjoy the show. 
A Japanese animated film debuted this screening style at its NYC and Los Angeles premieres in 2024, and we are now bringing Cheer Screening "Ouen Joei" to the global market.

Why dig deeper into the "Acoustic Technology"?

No matter how much time passes, sound will always be one of the five human senses. That is the founding belief that drives everything we do at Evixar.

We started with a simple question: what if the sounds already around us — in movie theaters, stadiums, train stations, on television — could silently carry information to anyone who needs it? Our answer became a long-term commitment to acoustic signal processing, driven by a vision of "a world where people use sound to see, connect, and enjoy."

This mission has a social dimension at its core. Our early work focused on cinema accessibility — enabling people with visual or hearing impairments to experience films on equal terms with everyone else, with no special infrastructure at the venue. The insight that emerged from that work shaped our entire approach: the most powerful technology is the kind that solves an extreme, specific need so elegantly that it becomes useful for everyone.

That philosophy — building outward from real human needs toward broadly applicable solutions — guides every product we develop: from cinema and theater accessibility (HELLO! MOVIE) to sound-triggered media (AiryMedia) to content authentication for the age of AI-generated disinformation (EAF - Evixar Audio Forensics／SIGNED SOUND).
