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 provenance and authenticity technology combining audio watermarking, audio fingerprinting and Content Credentials based on the C2PA™ (Coalition for Content Provenance and Authenticity) standard for audio and video (a C2PA conformant Generator Product), offered commercially as the third-party certification service SIGNED SOUND with Shachihata Inc.

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 and provenance of audio and video content in the age of AI-generated media, 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 have also been using it for major Hollywood titles.
We are now bringing "HELLO! MOVIE" to the global market as the new standard for visual and hearing accessibility. In July 2026, HELLO! MOVIE presented at the ICTA 2026 Summer Convention in Milwaukee, Wisconsin, introducing our BYOD approach to the international cinema industry.

EAF - Evixar Audio Forensics / SIGNED SOUND

EAF (Evixar Audio Forensics) is Evixar’s content provenance and authenticity technology for audio and video. It combines an audible-range audio watermark (EAW), audio fingerprinting (EFP) — both registered on the C2PA Soft Binding Algorithm List — and the generation and validation of C2PA Content Credentials, so that provenance can be recovered and verified even after a file’s metadata has been stripped or the content has been re-encoded.

This helps counter the misuse of AI-generated deepfakes. Content authentication and provenance technologies have been on the international policy agenda since the G7 Hiroshima AI Process (2023). Evixar works with the Japanese government on this issue 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. — the Japanese seal and stamp manufacturer — jointly launched SIGNED SOUND, a commercial third-party certification service for audio and video content. SIGNED SOUND attaches C2PA Content Credentials (C2PA Manifests) to audio and video files and embeds an audio watermark in the signal itself as a C2PA soft binding, so that a manifest can be recovered and the content's provenance verified even after the content has been re-encoded or redistributed across platforms.

In October 2026, EAF was listed on the C2PA Conforming Products List as a conformant Generator Product under C2PA Technical Specification 2.4 (Assurance Level 1), generating and validating C2PA Manifests for audio (FLAC, MP3, WAV, M4A) and video (MP4, MOV) files. Its audio watermark (EAW) and audio fingerprint (EFP) algorithms are registered on the C2PA Soft Binding Algorithm List. → Announcement

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).
