Ichihara Takenori

Takenori Ichihara is a Japanese manga editor and writer, best known for his transformative tenure as Editor-in-Chief of Weekly Shonen Sunday. He spent decades inside Shogakukan's editorial division, helping shape some of the industry's most beloved series before stepping away to write manga himself.

As of 2026, Ichihara is making his debut as a manga creator with Kimi wa Akeboshi: You're the Morning Star, serialized in Weekly Shonen Sunday with art by Aiko Koyama. The series follows an 18-year-old mage on a cozy road trip, a far cry from the high-stakes shonen action he once oversaw. Fans who followed his editorial career are watching this pivot with genuine excitement, curious to see how a master editor's instincts translate to the page. [edit]

Ichihara's professional life began in the trenches of manga editing at Shogakukan, where he worked directly with some of the medium's most respected creators. He edited series by Mitsuru Adachi, Hiroyuki Nishimori, Takuya Mitsuda, and Tanabe Yellow, learning the craft from the inside. That hands-on experience gave him an eye for story structure and character that would define his later leadership.

He rose through the ranks to hold dual titles of producer and deputy director at Shogakukan, supervising multiple magazine properties including Weekly Shonen Sunday and Gessan. By the time he took the top editorial chair, he had already spent years shaping the very magazine he would soon lead. [edit]

Ichihara became Editor-in-Chief of Weekly Shonen Sunday around 2015, a time when the magazine was reportedly on the brink of decline. His six-year tenure is widely credited with turning things around, and fan communities still discuss how he reformed the publication. He stepped down on October 13, 2021, then made a bold move: resigning from Shogakukan entirely on April 15, 2022, to write manga.

His new chapter began with a collaboration. In February 2025, he contributed text to Mainichi Adachi Mitsuru, a 408-page book celebrating Mitsuru Adachi's 55th anniversary. Then, on December 26, 2025, it was announced that he would launch a manga with Aiko Koyama. That series, Kimi wa Akeboshi, started in issue #8 (2026) of Weekly Shonen Sunday, following an 18-year-old mage named Azuki on a scenic, gentle journey. The reception so far suggests his editorial instincts carried over to writing. [edit]

Within manga fan circles, Ichihara is respected as the editor who saved Weekly Shonen Sunday from decline. Discussions on platforms like Reddit praise his editorial acumen and his willingness to take risks. His decision to leave a prestigious position to write manga added to that reputation, framing him as someone who practices what he preaches. The announcement of Kimi wa Akeboshi generated positive buzz, with early descriptions emphasizing its cozy, gentle tone. No fandom name or signature style has emerged, but his transition has made him a figure of interest. [edit]

Ichihara Takenori currently holds no global fame ranking within the iFANN database, as comprehensive data collection for his specific profile remains incomplete. Unlike performers who dominate charts or stage performances, his standing is defined by professional stature rather than viral celebrity metrics. The absence of a formal placement reflects the reality that his influence operates through editorial decisions and published works rather than public adoration or search volume spikes typical of entertainers. Consequently, no ordinal rank or scope can be assigned at this time, and any assumption of a position in the hierarchy would be speculative. Regarding his audience, there is no documented fandom name associated with Ichihara. While readers of Weekly Shonen Sunday may hold deep appreciation for the series he edited or the manga he now writes, this group does not organize under a specific moniker, nor do they engage in fan clubs, official rituals, or collective campaigns dedicated to him personally. His relationship with the public remains indirect, mediated entirely through the pages he curates and creates. There are no recorded instances of fan-funded billboards, birthday advertisements, or charity drives in his name, distinguishing his career from the mythos surrounding idols or actors. The lack of a named fanbase underscores his role as a behind-the-scenes industry figure whose legacy is measured in publication history rather than cultural phenomenon.[edit]

Ichihara's departure from his role as Editor-in-Chief to become a manga creator stands as a rare occurrence in Japanese publishing, where editors typically remain strictly within editorial divisions throughout their careers. During his tenure at Shogakukan, he accumulated broad oversight authority, holding the titles of producer and deputy director alongside his editorial duties. His long-standing professional partnership with Mitsuru Adachi reached a notable milestone with the creation of a 55th-anniversary book that reunited many of Adachi's former collaborators. In late 2025, Ichihara launched his debut series, Kimi wa Akeboshi: You're the Morning Star, serialized in Weekly Shonen Sunday with artwork by Akio Koyama, whose previous work Kiyo in Kyoto received an anime adaptation with English subtitles on NHK World. Unlike celebrities with viral legends, Ichihara's public narrative is defined by verified professional milestones rather than folklore; his resignation marked a candid shift in the magazine's production methods, though it did not spark the kind of street-shutdown reactions or fan mythology seen in entertainment circles. There are no recorded instances of crowds fainting or fans organizing charity drives in his name, as his relationship with the public remains indirect through the pages he edits and writes.[edit]

Details about Ichihara's family are not public. He has not shared information about parents, siblings, or his own household in any interviews or profiles. As a Japanese publishing professional, he has kept his private life out of the spotlight, focusing public attention on his work. [edit]

Ichihara's career is deeply tied to Mitsuru Adachi, whose work he edited and whose 55th-anniversary book he contributed to. He also worked with Hiroyuki Nishimori, Takuya Mitsuda, and Tanabe Yellow. His current collaborator is Aiko Koyama, creator of Kiyo in Kyoto, and they are co-creating Kimi wa Akeboshi. [edit]

No public information exists about Ichihara's personal relationships. He has not been linked to anyone romantically in any credible source, and his private life remains out of view. As of 2026, his relationship status is unknown. [edit]

Ichihara's net worth is not publicly documented, but per iFANN's editorial analysis, it is estimated at $2 Million as of 2026. His income stems from decades of service as a Shogakukan editor, where he earned a salary and likely bonuses tied to magazine performance. Since leaving the company in 2022, he has shifted to manga writing, earning serialization fees and royalties from Kimi wa Akeboshi. The exact figures are not disclosed, but his long career in a senior editorial role suggests a comfortable financial position.[edit]
