Ashita no Joe Creator Tetsuya Chiba Pauses His Autobiographical Manga for His Health

Tetsuya Chiba, one of the most decorated figures in manga history, has put his ongoing autobiographical series on hold due to poor health. The announcement landed quietly, inside the pages of the magazine that publishes it, rather than as a splashy press event — fitting for a creator whose entire late-career project has been about looking back on an ordinary life rather than chasing headlines. But given who Chiba is, it's news worth sitting with, not skimming past.

What was actually announced

According to Anime News Network, Chiba's hiatus was announced in Issue 19 of Shogakukan's Big Comic magazine, published Friday, September 27, 2026. In the announcement, Chiba said the severe summer heat may be behind him feeling unwell, and stated that he intends to focus on recovering so he can get back to drawing. Big Comic's editorial staff added that Chiba is eager to resume serialization as soon as possible, but that the magazine will prioritize his health and recovery over locking in any specific return date. That's the entirety of what's been confirmed so far — there's no diagnosis attached to the announcement, and nothing beyond "poor health" and a heat-related theory from Chiba himself has been given as a cause. It's worth being precise about that, both because Chiba is 87 and because it would be easy for secondhand summaries to inflate a cautious, vague statement into something more dramatic than what was actually said.

It's also worth flagging plainly how this story is currently sourced. As of this writing, the September 27 hiatus announcement has been reported in English by Anime News Network alone, citing Shogakukan's Big Comic as the original source. No second English-language outlet has independently picked up this specific story yet. That's not unusual for a manga serialized in a general-interest seinen magazine rather than one of the more heavily tracked Shonen Jump-adjacent titles, and ANN citing the publisher's own magazine directly is a solid primary chain — but it's a single-outlet report right now, and that distinction matters more than usual given how significant a figure Chiba is.

What Hinemosu Notari Nikki actually is

For readers who don't follow Chiba's non-Ashita no Joe output closely, Hinemosu Notari Nikki is worth introducing on its own terms. It's an autobiographical short-essay manga — closer to an illustrated diary than a traditional narrative series — that launched in Big Comic in December 2015. The title translates roughly to something like "an idle, meandering diary," and that framing tracks with its format: short, reflective, loosely connected essay-style chapters drawn from Chiba's own life and career, rather than serialized plot arcs in the way most manga readers are used to.

The series has been collected steadily since then. Its first volume was published in 2018, and its most recent, seventh volume came out in November 2025 — meaning this hiatus is interrupting a series that was still actively being collected into books less than a year ago, not one that had already gone quiet on its own. It's also worth noting this isn't the manga's first pause. Hinemosu Notari Nikki previously went on hiatus in August 2024 and returned that December, a gap of roughly four months. That prior pattern doesn't guarantee anything about how long this one lasts, but it does mean this isn't unprecedented territory for the series.

Why Chiba's name carries the weight it does

None of this would be a story worth a full writeup if it were an unknown creator's niche side project. It's a story because of who's drawing it. Tetsuya Chiba, born January 11, 1939, is best known as the creator of Ashita no Joe (Tomorrow's Joe), the boxing manga he drew from 1968 to 1973 that's widely credited — across manga scholarship and generations of creators who cite it as a formative influence — as one of the landmark works in the entire history of sports manga. Ashita no Joe isn't a niche classic; it's foundational, the kind of series that shaped how manga approaches struggle, defeat, and physical storytelling for decades of creators who came after it.

Chiba's career extends well beyond that single series, too. Harris no Kaze ran from 1965 to 1967. Notari Matsutarō, a golf manga whose title Hinemosu Notari Nikki's own name clearly echoes, ran from 1973 to 1993 and then again from 1995 to 1998 — an unusually long run even by manga standards. Ore wa Teppei ran from 1973 to 1980, and Ashita Tenki ni Naare ran from 1981 to 1991. That's a body of work spanning multiple decades and genres, from boxing to golf to general slice-of-life drama, produced by a single creator across most of the postwar history of the medium.

There's a minor wrinkle worth flagging on exactly when that career began: Anime News Network cites 1956 as Chiba's professional manga debut year, while Wikipedia cites 1958, tied to the work Butōkai no Shōjo. It's a small discrepancy and not one either source seems to be actively disputing so much as simply reporting differently — but it's the kind of detail that's easy to silently round to one figure, so it's worth naming rather than picking a side on.

A creator still adding to his honors this decade

What makes Chiba's current stature especially notable is that his recognition hasn't been frozen in the past — it's continued to grow well into his 80s. According to Anime News Network's 2024 coverage, Chiba became the first manga creator ever to receive Japan's Order of Culture award that year, one of the country's highest honors, typically reserved for figures who have made significant, lasting contributions to Japanese arts and sciences. Manga had never produced a recipient before Chiba. Two years earlier, in 2022, he became the first manga artist ever nominated to the Japan Art Academy, another marker of the medium's slow, historically uneven acceptance into Japan's broader fine-arts establishment. Chiba has effectively been the figure breaking those particular ceilings for manga as an art form, one institutional recognition at a time, well into a career that already spanned seven decades.

He also currently serves as chairman of the Japan Cartoonists Association, a position he's held since being appointed in July 2012 — meaning that alongside his own drawing work, Chiba has spent more than a decade as one of the manga industry's most senior institutional representatives, a role that adds context to why an announcement about his health, even a cautious one buried in a magazine's back pages, carries weight across the industry rather than just among his own readers.

The health context behind this pause

This isn't the first health scare Chiba has faced in recent years, either, which is part of why this hiatus reads as significant rather than routine. He underwent heart surgery with stent placement in January 2022, was treated for a throat tumor in 2021, and had eye surgery in 2024. Set against that recent history, an 87-year-old creator citing "poor health" and possible heat-related illness as reasons to step back from a monthly-cadence autobiographical strip is consistent with a pattern of ongoing, serious health management rather than an isolated one-off issue — though, again, nothing officially released ties this specific hiatus to any of those prior conditions. That connection is context, not confirmation, and it shouldn't be read as more than that.

What actually happens next

Big Comic's own framing is the most reliable guide to what to expect: Chiba wants to come back, but the magazine has explicitly said his recovery comes before any scheduling. That's a meaningfully different signal than an open-ended "on hiatus" notice with no further comment — it suggests active communication between Chiba and his editorial team, and a stated intent to resume rather than an ambiguous exit. The series' own history offers a loose precedent, too: the August-to-December 2024 hiatus resolved in a matter of months, not years. Whether that holds this time is genuinely unknown, and given Chiba's age and recent medical history, it would be irresponsible to treat that prior four-month gap as a predictor rather than simply the one data point available.

For now, what's confirmed is limited and worth restating plainly: Hinemosu Notari Nikki is on hiatus as of the September 27, 2026 issue of Big Comic, Chiba has cited feeling unwell with a possible heat-related cause, and Shogakukan has committed to prioritizing his health over any return date. Everything past that — how long the pause lasts, what specifically caused it beyond Chiba's own general comment — remains unknown, and should stay that way in any accurate accounting of the story until Shogakukan, Big Comic, or Chiba himself says more.
