Maybe you've watched most of the popular anime, but have you watched all the best anime on earth? In this article I am going to share the best anime that are unknown to most.
Anime that for the most part are better than the "popular" anime themselves, many are even among the best in the Japanese ranking, but even so it goes unnoticed by Brazilians, some are not even subtitled correctly.
Many of the anime on this list are in my TOP 10, if not TOP 3 of favorite anime. I get frustrated that no one knows these anime. I hope you enjoy the list of best unknown anime of all time.
Many anime on this list are not even present in other unknown anime lists. I hope you really like the anime that in my opinion are mandatory. Don't forget to share the list with your friends!
Table of Contents
Space Brothers
Already mentioned in an article as an unknown anime, Uchuu Kyoudai has a quite unique story, but it is perfectly executed, of high quality, and keeps you engaged from the beginning to the end of its 99 episodes.
The anime tells the story of Nanba Mutta, a man in his 30s who has made his living as a car designer, but who suddenly decides to follow a childhood dream that his brother managed to fulfill, to become an astronaut.
The anime during its release has always been among the TOP 5 of Japanese TV, beating anime like Naruto and even One Piece. The work also won movies and even a Live Action that I approve. Uchuu Kyoudai is in my TOP 3 favorite anime.
It may seem like an unattractive synopsis, but the anime features a lot of action, comedy, slice of life, with an epic soundtrack, good animation quality and a beautiful script. I guarantee that those who watched it, were interested and went to the end, including the reluctant ones.

Detective Conan - Detective Conan
This is considered one of the most popular anime in Japan, where even my mother likes to watch it. It is an anime as big as One Piece, with over 900 episodes and 22 movies. The anime has been in release from 1996 to today.
Detective Conan is a kind of Japanese CSI or Sherlock Holmes, where the protagonist is a schoolboy who was turned into a child by a secret organization. The anime has episodes with isolated cases and a general story, with frequent characters.
The anime is very good, despite some clichés that make it an anime suitable for children. Even though it is an anime with more childlike traits and approach, I doubt that children in Brazil have the ability to understand such complexity of this anime.
The anime, despite its children's content, is suitable for the whole family, has very complex explanations about crimes, has a psychological thriller, comedy and romance atmosphere. This anime is also among my TOP 3 best anime of all time.

Gyakkyō Burai Kaiji
Kaiji is a psychological thriller anime that ends up being ignored for its strong traits. The anime tells the story of a boy in debt who gets involved with suspicious men in a gambling game in order to pay off his debt.
The anime is quite interesting, presenting mental and psychological games involving life. It reminds me a lot of the dorama Kakegurui style anime, but not as crazy. Just the art style that keeps people from watching.
I strongly recommend ignoring the flaws and giving a chance to this great anime with two seasons and spin-offs. I also recommend the anime Akagi by the same author and with a similar story, but focusing on Mahjong.

One Outs - A baseball anime
If there's one thing I don't like, it's baseball matches for 25 episodes.
The anime is a bit old, unknown, but it hooked me from start to finish. Unfortunately, there was no continuation that I am looking forward to. I feel quite the absence of anime in this genre, it reminded me a lot of the atmosphere present in Kaiji.
The story begins when Kojima Hiromichi, the Lycaons' top hitter, heads to the south of the Japanese island of Okinawa to train. There, he meets Tokuchi Toua, a pitcher and undisputed leader of a form of baseball game called "One Out".

NHK ni yôkoso!
Tell the story of a Hikikomori in recovery (a person who lives trapped at home). An anime that has a psychological atmosphere, with plenty of comedy and that addresses issues of life, friendships, romance, work, and bullying.
The story centers around Tatsuhiro Satō, a 22-year-old unemployed, lonely, and depressed young man who dropped out of college. Believing he is part of a conspiracy, he leads a hikikomori life.
Living for years in his room being ed by his parents. Satō ends up meeting Misaki Nakahara, a mysterious girl who knocks on his door promising to help him stop being a hikikomori. Will he succeed?

Steins;Gate and Steins;Gate Zero
This is not very unknown, but it goes unnoticed by most Otaku. Some simply have the courage to drop this masterpiece in the first episodes, even after I insist that in episode 13 the anime turns your head.
This masterpiece of time travel approaches the concept in an epic way, with many twists and connections between all the first episodes, which at first doesn't make sense, but then it makes total sense and logic.
One of the best sci-fi anime of all time. It tells the story of a crazy young man who lives in his fanciful little club pretending to be a mad scientist. Until he unintentionally gets involved in conspiracies, time travel and murders.
For a long time this is one of my favorite anime, where I put it first or second in my list of the best anime of all time. A masterpiece both in story, soundtrack and character development.

Other Unknown Anime I've Watched
Ashita no Nadja - An anime quite old that aired on cable TV dubbed was one of the first animes I watched in my life. A very feminine shoujo, but it captivated me from start to finish, pulling me into the world of animes.
Monster - An old psychological thriller anime about a doctor who saves the life of a serial killer, loses his job, and ends up being sought by the police because of the murders. He chases after this serial killer to prove his innocence.
I''s Pure - A short anime in OVA with around 6 episodes that tell a cliché romance but touched me for a good while. This one is quite obscure and requires a lot of searching. I recommend taking a look.
Hunter x Hunter - It's not an unknown anime, but most of the supposed Otaku I know still haven't watched it. So I leave this here as a recommendation in case you haven't seen it yet, another one from my TOP 3 favorite animes.

God Eater - This anime attracted me because of the animation and battles, a quite futuristic and apocalyptic story. The anime is based on a series of Action RPG games mixed with a bit of Novel. I also recommend it. Black Bullet.
Seto's Bride - One of my favorite comedy animes that made me laugh from start to finish. It’s about a boy who gets engaged to a mermaid.
Digimon Savers - Among the existing Digimon animes, Savers has become one of my favorites for having older characters; even though it is one of the least popular in the series, I think it’s worth giving it a chance.
Pray no Imouto ga Konnani Kawaii Wake ga Nai - It's not so unknown, but many still haven't watched it. It's a Slice of Life with romance, addressing a rather controversial theme, otakus who play incest hentais.
GetBackers e Love Hina there were other animes that I watched on cable TV, but that are also not very talked about by people, even though they were aired in Brazil. They were some of the first animes I watched along with Fullmetal Alchemist.
Samurai Champloo - An interesting anime that tells the journey of a girl accompanied by two samurais.
