Visual Arts and its brand Key announced on October 19, 2026 that Jun Maeda has been diagnosed with pharyngeal cancer. Maeda felt discomfort in his throat in early spring 2026 and swelling and pain in summer, then received a diagnosis after detailed examinations at a medical institution. The announcement states that, after weighing his condition and treatment prospects, Maeda chose not to undergo aggressive treatment and instead receive care centered on palliative care so he could conserve his strength and continue creative work. He is hospitalized. Key says Maeda has completed his share of the Heaven Burns Red main story through the conclusion of Chapter 6, including lyrics and music for the first half of Chapter 6, and that further scenario and song work may not be possible as the illness progresses. A planned long-term YouTube music project has been changed to finishing existing songs for release in sequence.
The notice includes a mailing address in Naniwa-ku, Osaka, and an email, maedajun_message@visual-arts.jp, for letters of encouragement. Individual replies are not possible, and the staff ask fans to send letters only, with gifts and other get-well items declined.
The phrasing of the diagnosis differs by outlet: Anime News Network, GAME Watch, 4Gamer and Automaton say pharyngeal cancer, while Denfaminicogamer and KAI-YOU say hypopharyngeal cancer and Cinema Today and Game Spark say throat cancer, following the Japanese term used in the notice.
The announcement quotes the staff on his condition: "Maeda is currently hospitalized, but even so, he has a strong desire to devote himself to creative work until the very end. We would be grateful if you could warmly watch over these feelings."
Heaven Burns Red is a free-to-play RPG developed by Light Flyer Studio with Key. Its staff said in August that the game had started the final chapter of its main story, and the game launched in February 2022. Maeda was born in 1975 and is an executive officer of Visual Arts.
