Why did Chainsaw Man move to Jump+ for Part 2?
Part 1 of Chainsaw Man, the Public Safety arc, ran in Weekly Shonen Jump from December 3, 2018 to December 14, 2020. When the second part was announced in that same month, it had a new home: Shueisha's digital magazine Shonen Jump+, where Part 2, the School arc, began on July 13, 2022. Fujimoto has said he chose Jump+ to explore a completely different direction for the series.
He has also been candid about what the weekly magazine years cost him, and that record sits behind the move even where he does not draw the line himself. This page keeps the two apart: what he said about the choice, and what he said about the schedule.
The stated reason
A different direction, on the recordIn interviews collected after the move, Fujimoto said he chose to publish the second part on Shonen Jump+ to explore a completely different direction. He noted minimal differences in the editorial processes between the two magazines: a few depictions were adjusted at the rough draft stage, and he was granted full creative freedom regarding the story's logic. Part 2 delivered on the premise. It opened on a new lead, school student Asa Mitaka and the War Devil Yoru, with Denji attending school, a setup Fujimoto teased at Jump Festa 2021 before the first Part 2 chapter appeared.
The return was also a homecoming of a kind. Fujimoto's first serialized series, Fire Punch, had run on Shonen Jump+ from 2016 to 2018, so the platform was where he had started as a serial artist. Between the two parts of Chainsaw Man he published his two best known one-shots there as well: Look Back in July 2021 and the 200 page Goodbye, Eri in April 2022.
The schedule he left behind
His own words, 2022 and 2025Interviewed by French outlet BFM at the Angouleme festival in March 2022, Fujimoto described weekly serialization plainly: 'I work alone for a weekly magazine. It's incredibly difficult, and I don't want my series to get canceled, so I work non-stop.' He added that on a weekly schedule there is never enough time, that he improvised during inking to save time, and that he would have liked to draw characters and backgrounds himself but needed assistants for the backgrounds.
In the Love, Flower, Chainsaw Guide pamphlet given to Japanese audiences for the Reze Arc film in 2025, he went further about Part 1: 'It was my first time doing a weekly serialization, and it was honestly brutal. I was constantly worried it might get axed... I was so swamped that I barely slept. When my assistants came by, I still had to get up to greet them, so I ended up just sleeping by the front door.' Part 2 on Jump+ ran with visible breathing room, including short breaks Fujimoto explained himself: a week off when a chapter needed more pages, or when he had a volume cover to draw.
What the record does not say
The honest limitNo statement on record has Fujimoto saying he left Weekly Shonen Jump because of the schedule, and this page does not upgrade his two separate accounts into one cause. The documented facts are the choice, the reason he gave for it, and the conditions he described on both sides of it. Readers can weigh the connection themselves.
