Watching long-running anime series that run for years or even decades is a big commitment that everyone hesitates to make. This is especially the case for those just entering the anime world and wondering where to start.

Most fear choosing a series that would simply end up wasting your time. There are some anime that have been around for over two decades and still run strong. While short anime series are better for casual binge-watching, the longer series keep fans committed to them.

Perhaps the best part about long-running anime is that they always have something new to offer. With the endless line of characters and story arcs, these series never grow old. Here’s a list of 10 long-running anime series that you wouldn’t regret watching.
