20 Best Seinen Anime To Watch 2023

Best Seinen Anime To Watch

The world of anime has been around for a long time, and many different genres and sub-genres come with it. Seinen is one of the most popular genres in Japan: it’s geared towards a more mature audience and is often associated with violence.

What is the Seinen anime genre?

Seinen anime typically targets a demographic of male viewers aged 18-30. Generally, the Seinen series is more mature and deals with darker subject matter, violence, horror themes, or radical social commentary.


People sometimes mix up Seinen with dark and violent series, but that’s not quite right. Take “Attack on Titan,” for example. It has dark elements but is considered a Shounen series.

Seinen manga typically stand out by having more intricate plots, dealing with mature themes, or featuring older main characters than Shounen. Seinen stories are often more cynical and practical, although it’s not a strict rule.


So let’s check out some of the Best Seinen Anime you should watch.

I enjoy Seinen anime because it covers a wide range of topics. I usually pick the ones with high ratings on MyAnimeList and organize them by their release year. Here are some of my favorites.


Best Seinen Anime Recommendations

The movie’s portrayal of the neon-lit streets of Neo Tokyo was created using traditional cel animation techniques, which were pretty advanced for that era. The hard work put into it truly paid off. Even by today’s standards, this 1980s anime film stands out for its exceptional quality.

Its aesthetic, blending elements of technological dystopia, has had a lasting influence on the cyberpunk genre and continues to be appreciated today.

Later, there was a film trilogy titled Berserk: The Golden Age Arc, which came out in 2012. The next anime adaptation aired in 2016-2017, consisting of 24 episodes.

Which one should you pick? They’re all worth checking out, but the first anime from the mid-1990s has its unique charm. Even though the animation style is a bit old-school, it captures the dark atmosphere better.
