Start with the 2011 series: 148 episodes, a complete story, no prior viewing needed. Where the 1999 version fits, the films, and where the anime stops.
Two complete anime adaptations exist, made eleven years apart by different studios,
covering overlapping material to different endpoints. That is the whole obstacle. The
short version: start with the 2011 series, watch all 148 episodes, and treat the 1999
version as an elective for people who already know they love this world.
Why the 2011 series first
Madhouse's adaptation is the complete one. Across its 148 episodes it carries Gon and
Killua from the Hunter Exam through the Election arc, adapting further into the manga
than anything else animated has reached, and it ends at a point the story itself treats
as an arrival rather than a cancellation. It also assumes no previous viewing: the 2011
series is a retelling from chapter one, not a sequel, so nothing upstream is required.
The 1999 version, by contrast, stops partway and hands its remaining arcs to three
separate OVA series released between 2002 and 2004. Between the television run and the
OVAs it totals 92 episodes, and it never reaches the material the 2011 series finishes
on. It has also become genuinely awkward to watch legitimately: it left most streaming
catalogues years ago, and physical copies change hands at collector prices. None of this
makes it bad. It makes it a poor first door into the franchise.
The case for the 1999 version anyway
It deserves its hearing. The hand-drawn animation gives the early arcs a stranger,
heavier atmosphere than the remake's clean digital look, the Hunter Exam unfolds at a
pace that lets its dread accumulate, and some quiet character business survives only
there. Watch it after the 2011 series, when knowing what comes next turns the differences
from obstacles into commentary. As a starting point it asks for patience the story has
not yet earned; as a second pass it pays rent.
The films
Two films followed the 2011 series in 2013: Phantom Rouge and The Last Mission. Both are
side stories rather than canon, and both assume familiarity with the cast. Watch them
after finishing the series or skip them without losing anything; the consensus among
people who have seen both is roughly that they are for completionists, and neither
pretends otherwise.
Where the anime ends, and what comes after it
The 2011 series adapts the manga through the 13th Hunter Chairman Election arc, which
was chapter 339. Everything after belongs to the Succession Contest arc, which the manga
has been publishing in irregular bursts ever since, governed entirely by creator
Yoshihiro Togashi's health; weekly serialization formally ended in 2022, and new chapters
have arrived in batches since, most recently resuming again in mid-2026. The practical
consequence for a viewer is simple: the anime's ending is a real stopping place. Nothing
cancels mid-thought. Whether to follow the story further into print is a decision you
can make later, from a position of having finished something.
