Key’s Maeda Jun Has Pharyngeal Cancer, Will Keep Writing Heaven Burns Red

Visual Arts/Key announced on October 19, 2026 that Jun Maeda, the co-founder of Key and the scenario writer behind CLANNAD, Kanon, AIR, Little Busters and Heaven Burns Red, has been diagnosed with pharyngeal cancer. He has chosen palliative care so he can keep writing. The announcement came from Visual Arts and was reported in Japan by 4Gamer, Automaton JP and Game Watch; no English outlet had it before this morning.

Maeda began feeling unwell in the spring of 2026 and noticed throat swelling and pain over the summer. After diagnosis he declined aggressive treatment to preserve his energy for creative work. He is currently hospitalized. The same statement is in Japanese on the @key_official X account and on the Visual Arts/Key site.

The biggest impact is on Heaven Burns Red, the free-to-play RPG he has been writing for Wright Flyer Studios since the game’s February 2022 launch. Visual Arts confirmed he has finished his writing for the front half of Chapter 6, including its music (lyrics and composition), and that he has completed the main parts of the story through Chapter 6’s conclusion. Any further scenario or music work on the game may not be possible depending on his condition. A separate music project he had been planning will now be finished quickly and released on YouTube, instead of the long-form rollout he originally intended. Visual Arts/Key is also accepting fan mail at the Osaka office and has asked that gifts other than letters not be sent.

For Western players, the practical reality is more contained than the headline suggests. Heaven Burns Red’s main story through Chapter 6’s conclusion is already in the can, and the global Yostar client ships the same content, so the game is not being cut short mid-arc; the question is what comes after. The bigger question for Key as a studio is succession: the publisher has rarely if ever had to write a long-running Maeda-led scenario without Maeda, and the press release is unusually clear-eyed that no other writer is being lined up. The trade-off Visual Arts/Key is taking is straightforward. Finish the main story under the original author, then let the writer’s voice fade rather than bring in a stand-in.

The music-project shift is the more unusual detail. A long-form YouTube rollout was already in motion before the diagnosis; the change is the timeline, not the format. That is the line to watch over the next few weeks, since it gives a concrete signal of how Maeda’s condition is developing in public, even when Visual Arts isn’t posting updates.

Can you play it in English?

Yes. Heaven Burns Red launched worldwide via Yostar on November 15, 2024 on iOS, Android and Windows PC (Steam appid 1984470), fully playable in English with the same gacha and story content as the Japanese client; there is no Switch version and no console SKU, and Key/Visual Arts has not yet posted an English-language version of today’s statement. The game’s status in our Coming West tracker is unchanged by this news, since the global Yostar client is already live.

Key, CLANNAD, WFS, Yostar in plain English

Key is the visual-novel brand under Visual Arts/Co. founded in 1998 by Maeda, Itaru Hinoue, Shinji Orito and others after they left the Tactics brand. CLANNAD is the 2004 Key visual novel widely credited with popularizing the “crying game” (泣きゲー) genre outside Japan, and is the work most Western fans know Maeda for. Wright Flyer Studios (WFS) is a Visual Arts subsidiary that co-develops and operates Heaven Burns Red. Yostar is the publisher that runs the global English client outside Japan.
