Manga that went on hiatus primarily due to the health problems the creators may be facing, making it one of the more heart-wrenching stories of the industry. These insane production schedules mangaka face are so savage that they push these individuals near their limits of physical endurance.
Japanese manga has recently changed quite a bit. Before, many creators would draw for months to produce a chapter. Now, every week, they must create an entire chapter (20 pages) while still maintaining quality and adding a great storyline. This pressure-cooker environment has forced numerous talented artists to step away from their work.
Manga that went on hiatus due to the author's health
1. Gangsta remains unfinished after Kohske's diagnosis
Gangsta has been on hiatus since 2020

Since 2020, Kohske, the creator of the popular crime series Gangsta, has been on hiatus due to health issues associated with lupus, which he announced on his social media page. Kohske has taken multiple breaks from Gangsta over the years and has had health challenges before receiving his lupus diagnosis.
Gangsta is a well-received crime-drama series with an interesting cast of characters and, overall, a lot of critical acclaim. Lupus, at its core, is a lifelong chronic disease that requires continual management and lifestyle changes. Among manga that went on hiatus for health reasons, Gangsta’s situation exemplifies how serious medical conditions can indefinitely derail even successful series.
2. Historie pauses as Iwaaki focuses on recovery
Historie went on hiatus after chapter 124

Hitoshi Iwaaki started working on a historical manga based on Eumenes of Cardia, but in March 2022, he had to stop working on the manga due to health issues. He will return to finish writing the ending once he gets well.
Even though the 12th volume came out in 2024 (implying that some progress on this series has been made), fans have yet to see anything new since then. Iwaaki’s other work, Parasyte, proves he is an amazing writer, so everybody is anxious to see him finish Historie.
3. xxxHOLiC: Rei experiences repeated interruptions
xxxHOLiC: Rei has been on giatus since 2017

CLAMP’s sequel is supernatural-related, but it has had numerous release delays since its 2013 original publication. The female creator group announced that a new series would be published in Spring 2023, but the announcement appears to be false. These manga that went on hiatus are common for CLAMP’s works.
The four people on the team have dealt with a variety of physical and mental health problems during their careers as comic book artists. Because of these health issues and the fact that all four of them have an insane amount of projects all the time, it’s very difficult for CLAMP to get a new comic book out regularly.

Readers were left hanging at the end of this story with all sorts of things unresolved. This manga that went on hiatus serves as a reminder that some health challenges require permanent lifestyle changes.
6. Frieren: Beyond Journey's End surprises fans with recent hiatus

Fans are freaked out by the announcement that Frieren: Beyond Journey’s End has a long break coming. Tsukasa Abe and Kanehito Yamada created this series back in 2020, and it’s been releasing new chapters at a regular pace since then. But now that it has developed into this huge success so quickly, for them to announce they’re taking a long break comes as a huge shock to many fans.
There has been no official confirmation from the creators about the manga that went on hiatus due to health problems. However, there is speculation of physical or mental difficulties because of the amount of work it takes to keep the manga at the level of quality the creators desire.

8. World Trigger struggles with author's recurring health problems
World Trigger has taken multiple breaks since 2013

Daisuke Ashihara’s sci-fi series has seen its fair share of bumps in the road due to continuing health issues with the author. Daisuke has suffered from cervical spondylosis since 2014; it’s a condition that causes significant discomfort and pressure on the spinal nerves.
In addition to the pain caused by his condition, Ashihara also has to take breaks to treat his pain so that he can continue drawing his manga. The most recent hiatus in 2025 continues this pattern. Despite these manga that went on hiatus, the series maintains a devoted fanbase.
