■ Award Comments

◆ Director | Mamoru Shinoda
Thank you very much for this honor. This work was not accomplished by my efforts alone, but thanks to screenwriter Shirakawa-san, all the staff and cast members involved, and above all, the viewers on the other side of the screen who were moved and stopped to watch this video.
The theme “What if humanity became dependent on AI?” was very social and captured people’s hearts, so as a director, I tried to depict it realistically while bringing out the impact of the worldview.
I will continue to create dramas that move your hearts, so I look forward to your continued support.
◆ Screenplay | Tomoki Shirakawa
When feeling a little sad, when facing a slightly difficult problem, chat AI as a consultant has permeated society as an indispensable presence.
I wrote this work thinking that 10 years from now, it wouldn’t be strange if people had become completely dependent on chat AI and blamed chat AI for their failures—if society had become like that.
I am greatly honored to have been selected for such a prestigious award. I have been working on short dramas for over a year with this award as my goal, so I am extremely happy and truly proud of everyone involved in this work. Thank you very much.
■ About “Seikaiwakaranai”
“Seikaiwakaranai” is a vertical short drama account originating on TikTok, planned, produced, and operated by OASIZ Inc. It is one of the core IP accounts that has been operated since the early days of OASIZ’s establishment, and has continued to depict the emotions, friendships, romance, SNS, family, job hunting, dreams, and more of people in their teens and twenties living in an “era where there are no right answers” through short-form dramas.
Rather than denying that “there are no right answers,” we pose this uncertainty to the world through short dramas, appealing to the importance of finding one’s own right answers.
