Hunter × Hunter manga has completed over 1000 days of hiatus. The manga is written and illustrated by Yoshihiro Togashi. Hunter × Hunter went on hiatus after chapter 390 which was released on November 26, 2018.
Hunter × Hunter is considered as one of the finest shounen manga. Despite the hiatus popularity of Hunter × Hunter anime and manga keeps on increasing day by day.
Reason for hiatus:
Yoshihiro Togashi has been suffering from back problems. He has chronic pain in his back which makes him unable to draw manga chapters as it requires long sitting hours.
However, the good news is that the author has not given up on writing the manga and has said that he will try his best to finish the manga once his back problem is over
Hunter x Hunter is set in a world where Hunters exist to perform all manner of dangerous tasks like capturing criminals and bravely searching for lost treasures in uncharted territories. Twelve-year-old Gon Freecss is determined to become the best Hunter possible in hopes of finding his father, who was a Hunter himself and had long ago abandoned his young son. However, Gon soon realizes the path to achieving his goals is far more challenging than he could have ever imagined.
Along the way to becoming an official Hunter, Gon befriends the lively doctor-in-training Leorio, vengeful Kurapika, and rebellious ex-assassin Killua. To attain their own goals and desires, together the four of them take the Hunter Exam, notorious for its low success rate and high probability of death. Throughout their journey, Gon and his friends embark on an adventure that puts them through many hardships and struggles. They will meet a plethora of monsters, creatures, and characters—all while learning what being a Hunter truly means.
