Yuki Kaji Explores Soyogi Fractal on Daisuke Sakuma's Radio Show
The world of voice acting and idols is coming together once again! It has been officially confirmed that the legendary voice actor Yuki Kaji will be making a very special guest appearance on the popular Nippon Cultural Broadcasting radio program, Snow Man Daisuke Sakuma's Wait, Impossible, Tired.... This exciting episode is scheduled to be broadcast on February 28th, and fans are already counting down the days to hear these two stars interact.

In the picture above, you can see Daisuke Sakuma from the famous J-pop group Snow Man on the left, standing alongside Yuki Kaji. Both of them look quite excited for the recording session, and honestly, the energy they bring is just amazing.
A Deep Dive into the Soyogi Fractal Project
For those who don't know, Snow Man Daisuke Sakuma's Wait, Impossible, Tired... is a dedicated 60-minute weekly program. It is a space where Sakuma, who is a massive fan of the medium himself, talks freely about his favorite anime and games. This isn't just a regular talk show; it’s a place where genuine passion for otaku culture is shared with thousands of listeners across Japan.
This upcoming episode marks the second time Yuki Kaji is visiting the show. The chemistry between the two is already well-established because they have worked together before. For instance, they both lent their voices to the TV anime Inherit the Wind. Because of this prior professional relationship, the conversation flows very naturally between them.
During the February 28th broadcast, the duo will be taking a deep dive into Kaji’s latest ambitious venture. He is currently developing a voice AI project titled Soyogi Fractal, which is actually based on his own iconic voice. They will specifically discuss Soyogi Bon, the voice AI character at the heart of the project. It is quite a futuristic concept, and seeing a veteran like Kaji embrace this technology is really something else.
Celebrating a Milestone: The 200th Broadcast
The timing of this guest appearance is also very special. After the recording session was over, Kaji shared some very heartfelt comments about his experience. He was quoted saying, "Congratulations on the 200th broadcast! I am very honored to be invited as a guest again at this memorable time of 4 years since the program started!" It’s clear that he has a lot of respect for what Sakuma has achieved with this radio show over the years.
Kaji also mentioned how impressed he was with Sakuma's reaction to the new AI software. He said it was truly moving to see "Sakkun" (Sakuma's nickname) so fascinated by the technical details of the Soyogi Fractal project. Kaji has dedicated a lot of his life to this project lately, so having a friend show such genuine interest meant a lot to him.
Looking Forward to Soyogi EXPO
Apart from the AI talk, the show will also highlight the upcoming large-scale live performance known as Soyogi EXPO. This event is set to take place at the Tokyo Garden Theater on March 8th.
