Suzumiya Haruhi no Yuuutsu (2009)

The Endless Eight episodes will definitely bring back memories if you watch this excellent horror anime. Higurashi has an eternal June, while the Melancholy of Haruhi Suzumiya had an eternal August. Both are solved by the most simplest/unlikely of solutions. As well, everyone will definitely enjoy how the end results of Higurashi actually DOES change (unlike in Endless Eight, where Yuki Nagato states how some things were omitted, but those changes where never actually animated). 

the endless 8 ark in Haruhi goes back in time in each episode and Yojouhan Shinwa Taikei (or Tatami Galaxy) goes back in time in each episode both for a silly reason that the main character forgot to do something in Haruhi no yuuutsu there aren't many changes but in Yojouhan Shinwa Taikei most of the episode is different they also both give you that de ja vue feeling  

Although Higurashi is less repetitive, both are second seasons with the idea of an 'eternal summer', only one person who remembers all of it, deja vu with the other characters, and a 'god' behind all of it. 

Just because both Haruhi and Yuri both look the same and almost has the same personality. Haruhi has the SOS Brigade and Yuri has the SSS. What more you want? 

If you are a fan of time travel and parallel universes, then you are surely to like these two. Both have a different way of story telling apart from other anime that would be a refreshing change of pace. the two have terrific plots and awesome likable characters. They also not fall apart in terms of enjoyment level, comedy and drama. 

A group of friends decide to shoot a movie during summer break; the plot and characters in the movies on both series closely reflect the strange and secret truth about one or more characters or situations in the show even though it's not known by everyone participating in the creation of the film (On 'Haruhi' she's the only one who doesn't know the truth, on 'Ano Natsu De Matteru' most of the characters don't know). That's just about where the similarities end as far as a can recall. 

If you like Sakuta then maybe you'll probably like Kyon too. They might not be similar as Sakuta is really inlove with Mai and is witty, while Kyon is expressive and short tempered. But the story do have similarities as both the series revolves around the supernatural happenings around them. 

Two strong-willed, brash characters (Suzumiya Haruhi and Aki Tomoya) manage to find themselves the leader of a devout group of friends who will fulfill their personal goals, despite them being unreasonably difficult to deal with. The entire story revolves around these two characters, rather than them being a part of a bigger story. A small difference between the two is that Tomoya is the "main" character while Haruhi is somewhat of a deuteragonist in her own story. 

The story center around male protagonist who been surrounding by abnormality/oddities for example - Bakemonogatari - apparitions: gods, ghosts, myths, and spirits Suzumiya Haruhi no Yuuutsu - Alien, esper and time traveler. Both male protagonist also have lots of similarity cause they do everything in their power to save/to change to better situation for the whole series. - If you enjoy Suzumiya Haruhi no Yuuutsu you might as well enjoy Bakemonogatari!!! 

While both have different storylines, the lightheartedness and the supernatural come together to form something entertaining. Especially if the latter is far better than the superior. 

A group of high school students filming a low-budget sci-fi movie, with intentionally bad acting, shot composition and editing. Kannagi's visual style resembles a lot early Kyoto Animation works, and the director, Yamamoto Yutaka, worked on the first season of Haruhi. 

Endless Eight and the entirety of Sotsu were essentially recaps of a previous experience being told in a different way or perspective, though Endless Eight felt more rewarding than whatever the fuck Sotsu managed to be. 

A mildly reminder that this rec actually contain a very subtle obvious spoiler: So whats make this two similar? Summer Time loop Playing in the water Supernatural event Watch each, and you will get the vibe i mentioned above. Even if its not very well same in the grand concept of both series stories.  

People with supernatural abilities suddenly find themselves in the same school club and then proceed to make use of their superpowers to solve problems or save the world. These two anime give pretty much the same vibe, except that Charlotte is much more serious, while SHnY is more comedic and intricate plot-wise. 

Two somewhat similar, serious male protagonists, find themselves suddenly surrounded by a cast of rather weird people with which they live their school life and experience dozens of things. Clannad and Suzumiya Haruhi no Yuuutsu feel similar: nostalgic, comedic, but also capable of giving you some sense of melancholy at times. 

both have normies being caught up in weird antics and are focused around clubs as well too.  

Tales of high school a particular high school club, consisting of exactly 5 people (2 boys and 3 girls). In both clubs, MCs investigate and ultimately resolve some supernatural occurrences. Both focus on the relationship of members of the club. *By Suzumiya (2009) I meant watching all 28 episode in the order aired on 2009. 

While the stories themselves might not have many similarities, both series bring about the same feelings and moods. They have a few themes in common and even character similarities and watching both series gave me the same kind of vibe. If you enjoy one, it's definitely worth giving the other a chance. 

The protagonist Shin reminds me of Kyon's personality, especially the part when he is having conversation with his own head. Noe's personality reminds me of Haruhi + Yuki. 

Feeling mighty Groundhog Day in both. 

Both became infamous somehow. Criticized everywhere, hated online, and subject of many f-word, anime industry at its best. Story-wise nothing is much similar. For exact comments on why it is hated please ask the haters themselves. The so-called haters are available online for your convenience. 

Main characters' important target: breaking up a mysterious infinite loop. There are arguments and assumptions about God, too. 

Similarities: Both involves a mucahcho who happens to be the only normal hombre in a group of poco loco chiquitas. Both involves a chiquita who is the most weirder of all. Both have sci-fi genres. And in both cases, the muchacho is drag into the chiquita's weird world. Dissimilarities: In DOSO the muchcho almost never encountered any esper or ET beings, while the same cannot be said with the muchacho from SHY. In SHY the muchacho was able to develop a relationship with the chiquita, while in DOSO the muchacho is sometimes being sexually harass by his MILF aunt. When it come to the extra genre, DOSO is more of drama than sci-fi, while in SHY it's genre has romance as an extra genre, but it is more of mystery than sci-fi.  read more 

Both shows have a similar structure and general tone. The stories are told from the perspective of a "straight-man" main character, who reluctantly gets himself involved in the shenanigans of a curiosity-stricken female lead. The supporting characters also show a number of similarities between shows, and both also offer the interesting narrative quirk of adding the main characters thoughts to spice up the dialogue. Though Haruhi is more upbeat than Hyouka, both make for a wonderfully interesting experience. 

While not entirely similar by genre standards, Haruhi and Isshuukan Friends gives off a similar vibe with its cast of characters. They both follow a slice of life format although Suzumiya Haruhi no Yuuutsu has the additional element of supernatural element in it. But that element also turns into an arc that shares a similar concept to Isshuukan Friends. Both series tells a story with friends in a lighthearted school life setting where there's any possibility. If you're into stories with a simple yet appealing concept involving memory loss (for Suzumiya Haruhi no Yuutsu, involving a particular arc), give both series a try.  

The Endless Eight really reminded me of this OVA involving the theory of time travel/loops. There's also some emotion and drama in both series as well as comedy. (more in Haruhi). Both anime(s) are something to keep an eye on. 

There is always so much that can be done with the theme of time travel, yet there are so many anime that deals with this wide theme and does things their own way. Suzumiya is a unique experience dealing with time travel and other out of this world phenomenons. It is one trip through time, going through the cycles of time or back in the past with varied experience. Just as re:zero has a few episodes with similar experiences repeated but varied slightly each time to further the plotline, Suzumiya also has several episodes one after another, which may make you think that you are watching the same episode as before, but if you watch closely enough, you will see the differences in each episode. These events happen until something finally breaks this endless cycle of time repeating itself, and that's when you find out all the secrets behind this time loops. A time loop is just one fraction of Suzumiya, but there is so much more going on. The same could be said with re:zero, that there is so much more beyond the main character's time loop.  read more 

Both of these anime require an effort from the viewer to understand their deeper meanings. If you enjoy analyzing things beyond what appears on their surface, you will enjoy both of these. Both appear shallow on the surface, but you must watch carefully and pay attention to small details to get what the creators really want you to see.
