On March 8, 2026, Yuki Kaji’s voice-AI project Soyogi Fractal will reach its climax with Soyogi EXPO, a 3D entertainment live event at Tokyo Garden Theater in Tokyo. And starting today, November 21, 2025, fans can jump in early: the fastest ticket pre-sale has opened exclusively on the special website, just as the 18-track compilation album “0rigin” begins streaming worldwide at midnight JST. If you’ve ever been curious about Bon Soyogi, AI x human performances, or how overseas fans can still be part of the story, this is the perfect time to dive in.
Soyogi EXPO and Soyogi Fractal at a Glance for New Fans
If the words Soyogi Fractal or Bon Soyogi are brand-new to you, don’t worry—you’re exactly who this article is for.
Soyogi Fractal is a voice-AI character project built around the voice synthesis software “Soyogi Soyogi,” created from the real voice of voice actor Yuki Kaji, known worldwide for roles like Eren Yeager in Attack on Titan and Shoto Todoroki in My Hero Academia. The project was launched as part of his 20th anniversary as a voice actor and aims to be a creative “fractal” where pros and amateurs can freely make music, videos, and stories together with this AI voice.
Bon Soyogi (梵そよぎ) is the character form of that voice: “another Yuki Kaji from a different world,” who grows through collaborations with different creators. Soyogi EXPO is positioned as a major, culmination-style live event for this whole project—a place where everything created around Bon Soyogi converges into one night.
AI and Human Sharing the Stage at Soyogi EXPO 3D LIVE
So what actually happens at Soyogi EXPO? In short: AI and human literally share the same stage.
A 3D model of Bon Soyogi will appear on the big screen, performing original songs, cover tracks, and even duets with Yuki Kaji himself. On top of the music, the event features elements like reading theater, live dubbing-style performances, and vocal acting segments that let you feel the “analog” side of Kaji’s performance right next to Bon’s digital presence. It’s less “AI replacing people” and more “AI and a human partner creating a new kind of show together.”
Visually, the event is anchored by a powerful key visual drawn by Kohei Horikoshi, the creator of My Hero Academia, depicting Bon Soyogi standing in a festival-like space with a determined gaze. It immediately signals to anime fans that this isn’t just a tech demo—it’s a full-on character-driven entertainment project.
Key Guests, Music Creators and the Bon Soyogi Worldview
The guest lineup reads like a mini anime event on its own. Alongside Bon Soyogi and Yuki Kaji (Soyogi Fractal’s general producer), the stage will feature Nobuhiko Okamoto, Takuma Terashima, and Daiki Yamashita at both the daytime and evening shows, with Hiro Shimono joining the daytime performance only. For seiyuu fans, this alone makes Soyogi EXPO feel like a mini all-star festival.
The music side is just as stacked. The compilation album “0rigin”, created for Soyogi EXPO, gathers 18 tracks by a lineup that includes names like Hiroyuki Sawano, KOHTA YAMAMOTO, Tomoya Tabuchi from UNISON SQUARE GARDEN, Revo (Sound Horizon / Linked Horizon), and more. Each artist wrote their track based on Soyogi Fractal’s concept and Bon’s identity—so listening through the album is like walking through different “rooms” of the same shared universe.
Dates, Tickets and Seating Details at Tokyo Garden Theater
Soyogi EXPO—officially titled Bon Soyogi 1st EXPO “0rigin” (with a zero in “0rigin”)—takes place on Sunday, March 8, 2026, at Tokyo Garden Theater in the Ariake area of Tokyo.

0rigin Compilation Album: Eighteen Songs Shaping the EXPO
To set the mood, the team has released the compilation album “0rigin” on music streaming services from 00:00 JST on November 21, 2025. All 18 tracks were produced for Soyogi EXPO, and many of them are expected to appear in the live setlist in some form. According to the official description, every vocal track uses the Soyogi Soyogi voice synthesis, making the album a pure example of Bon Soyogi “singing” through different creators’ filters.
If you’re an overseas fan, this album is your easiest entry point: just put on headphones and let Bon’s voice lead you into the project’s world—even if you’re nowhere near Tokyo. You can find platform links via the official distribution hub: Stream 0rigin.
