Vagabond

Yes, Takehiko Inoue's Vagabond has been on an extended hiatus since around 2015, with no announced date for its return. Inoue has stated the series is not officially cancelled but that he needs to figure out how to properly conclude it. The manga currently stands at 37 volumes, with the story well beyond the famous duel between Musashi and Kojiro Sasaki.

Vagabond is a fictionalized biography of Miyamoto Musashi, Japan's most famous swordsman, who lived from 1584 to 1645. The manga is specifically adapted from Eiji Yoshikawa's novel Musashi, which itself takes considerable creative liberties with the historical record. Many characters, including Musashi's rival Kojiro, are based on real individuals from the early Edo period.

Vagabond is widely regarded as one of the most visually accomplished manga ever created, with Inoue using traditional ink brush techniques for many of its pages. Rather than focusing purely on action, the story is deeply philosophical, exploring Musashi's internal journey toward understanding what it means to be truly strong. Themes of Zen Buddhism, agriculture, and the meaning of mastery are woven throughout.

Inoue has never officially cancelled the series and has occasionally reassured fans that he intends to return to it. However, he has been simultaneously working on Real, his wheelchair basketball manga, which is also ongoing. There is currently no confirmed timeline for Vagabond's completion, making it one of the most famous unfinished manga in the industry.
