Nankai Trough Kyodai Jishin Manga on Short Hiatus as Artist Kumichi Yoshizuki Prioritizes Health

The creator of the realistic disaster manga Nankai Trough Kyodai Jishin (Nankai Trough Megathrust Earthquake) has announced a brief publishing hiatus to focus on their health. Artist Kumichi Yoshizuki revealed the decision after consulting medical professionals, estimating the break will last roughly two months following the recent release of chapter 33 for Kodansha’s Magazine Pocket premium readers. Fans can expect the series to resume once Yoshizuki recovers and medical guidance permits.

What the Hiatus Means for Readers and Serialization

The announcement comes after chapter 33 was made available for premium users on Magazine Pocket. A roughly two-month hiatus indicates a short-term pause rather than an indefinite cancellation — a common and often necessary step when mangaka need time to recover. While serialization schedules can be tight, publishers and readers increasingly accept breaks when creators cite health reasons; this helps protect the artist’s long-term ability to continue the series.

Timeline: Recent Releases and Expected Return

Key timeline points for the series:

• July 2024 — Nankai Trough Kyodai Jishin launched on Kodansha’s Magazine Pocket, written by biki with art by Kumichi Yoshizuki.
• April 23, 2025 — The fifth compiled book volume (tankōbon) was shipped by Kodansha.
• After chapter 33 (recent premium release) — Yoshizuki announced a health-related hiatus, estimated at about two months.

These dates place the pause as a short-term break in the run of a series that has already built momentum through regular web serialization and compiled volumes.

About the Series: A Gritty, Interview-Driven Take on the Nankai Trough Threat

Nankai Trough Kyodai Jishin stands out for its attempt to portray a highly plausible scenario: the megathrust earthquake that scientists have long predicted for the Nankai Trough, a major seismic zone south of Japan. The series draws on in-depth interviews and research to dramatize the potential human, infrastructural, and societal impacts of such a catastrophic event. The last comparable megathrust earthquake in that region occurred in 1946, and the manga leverages that historical context to heighten realism and urgency.

Realism through Research

By blending interviews with experts and survivors’ perspectives, the manga emphasizes the human stories behind disaster preparedness and response. That research-driven approach gives the narrative a documentary-like weight that appeals to readers interested in both speculative disaster fiction and grounded social drama.

Visual Storytelling and Narrative Focus

Artist Kumichi Yoshizuki’s line work and panel composition aim to balance intimate character moments with large-scale destruction sequences—an approach that helps the series convey both the emotional and physical scale of a megathrust event.

Kumichi Yoshizuki: Career Highlights and Related Works

Yoshizuki is an established manga artist with a varied portfolio. Notably, they collaborated with Yuhei Aoki on the Aa Shūkatsu no Megami-sama (Ah My Job-Hunting Goddess) spinoff, based on Kousuke Fujishima’s classic Oh My Goddess! franchise, which ran in Monthly Afternoon from January 2018 until October 2021. Additionally, Yoshizuki’s earlier collaboration on Someday’s Dreamers (adapted from a story by Norie Yamada) reached international readers through Tokyopop and inspired two television anime adaptations and a live-action film; Sentai Filmworks later released the anime on home video in North America.

This background highlights Yoshizuki’s experience with both slice-of-life and fantasy properties, making the pivot to a realistic disaster manga a notable expansion of their repertoire.

What Fans Should Expect During the Hiatus

During the two-month break, readers can reasonably expect:

• Potential re-reads or catch-up opportunities for new readers to buy volumes or read earlier chapters on Magazine Pocket.
• Publisher updates regarding the exact return date; Kodansha typically posts notices when serialization resumes.
• Possible promotional activity timed around the tankōbon releases once the series is back on schedule.

Fans can also use this time to revisit the series’ themes and to explore interviews or creator notes that shed light on the manga’s research and development.

Where to Read and Official Releases

Nankai Trough Kyodai Jishin is serialized on Kodansha’s Magazine Pocket platform and has been collected into tankōbon volumes, with volume 5 shipped on April 23.

How This Hiatus Fits Broader Industry Trends

Short health-related breaks are becoming more visible in manga publishing as creators and publishers balance output with wellbeing. While fans naturally want ongoing chapters, supporting a mangaka’s recovery often preserves the quality and longevity of a series. In practice, these pauses can lead to healthier work rhythms and sustained storytelling quality over time.

Final thoughts

While any hiatus can feel disappointing to devoted readers, Kumichi Yoshizuki’s decision to prioritize health after chapter 33 is a wise and humane step. Nankai Trough Kyodai Jishin’s grounded, research-backed portrayal of a potential megathrust earthquake has set it apart, and taking the time needed to return in good health will help maintain the series’ artistic standards. Fans should watch for official updates from the artist and publisher, use the break to catch up on the story or collect the tankōbon volumes, and look forward to the continuation of a drama that combines technical realism with powerful human storytelling.
