History
Studio Kai was founded in June 2019 by ADK Emotions, a company within the ADK group with interests in advertising, entertainment, and intellectual property. The new studio was established in Tokyo during a period when Japanese media groups were seeking to strengthen their control over anime production and related rights. Rather than operating solely as an independent animation contractor, Studio Kai was structured to participate in both production and anime-related intellectual-property business. In July 2019, only a month after its establishment, Gonzo transferred part of its anime production, intellectual-property, and rights-management business to Studio Kai. The transaction connected the newly formed studio with Gonzo’s existing animation activities and gave it a production and rights-related foundation beyond that of a completely new entrant. The available reference material does not specify the individual titles, personnel, contracts, or assets included in the transfer, so those details cannot be stated with certainty. Studio Kai’s documented activities span the main formats used by the Japanese animation industry: television series, films, original net animation, and original video animation. One specifically identified credit is episode 6 of Hori-san to Miyamura-kun, released in 2021. The available sources do not provide enough information to reconstruct a complete production chronology or to determine the studio’s precise role in every title associated with it. Financial results became an important part of the company’s history. Studio Kai reported a loss of ¥165 million in 2020. The loss suggests that the studio faced economic challenges during its early operating period, although the available material does not explain whether these arose from production costs, delayed projects, financing arrangements, or broader market conditions. No reliable information is provided about revenue, employee numbers, capitalization, or subsequent annual performance before 2025. According to the supplied reference material, Studio Kai filed for insolvency on April 13, 2026, after reporting a loss of ¥565 million in 2025. The filing represents a major turning point in the company’s corporate history, but the available information does not establish whether the filing resulted in liquidation, restructuring, acquisition, or another legal resolution. Accordingly, Studio Kai’s current status remains unknown in this dossier. Its documented history is that of a recently established ADK-affiliated Japanese animation studio that inherited part of Gonzo’s anime-related business, produced or participated in anime projects, and later encountered severe financial distress.
