Now GoGoAnime offers a wide mix of old, rare, and the most recent anime to watch. All clips, episodes, films and series are in alphabetical order so it is simple to find what you are looking for. There are several options on how to download each bit of anime and it is recommend that you select the OpenLoad option when downloading any anime.
Now not all of the anime available on 9anime has been dubbed or subbed into English yet there is a list of the series that has been. You can filter your research by the date of original release, or by the most trending series or films. The search will also show you the latest available episodes for long running series.
Originally called Anime44, Animenova has an extensive catalog of both anime and magma that is constantly updated to coincide with what is available in Japan. This means you can watch even the longest running series and never miss new shows either.
You just need to be patient with all of the adverts running in between episodes.
Kouraoni is a newer site, and as such it does not have the most extensive catalog of anime. However, the catalog is been added to on an ongoing basis so the level of choice is increasing all of the time. This is definitely a case of a work in progress yet is worth trying to see if you like the site.
Aside from Japanese anime, AnimeFrenzy also allows users to watch American animation series. The site also has a chatroom for every series you can watch, so you can chat with others watching the same series that you are.
A different feature with this site is that it has a random button. Press it and it plays a random episode or film, helpful if you cannot make up your mind what you wanted to watch.
