Amanchu!

Same director/author. The similarities are everywhere  

This applies to the entirety of the Aria franchise, not just this season. Both shows are very similar on mood, coziness, and general atmosphere. They were created by the same author, so it's no surprise that there are very similar elements throughout. They both have fantastic characters that are always a charm to watch. They also both sometimes get a bit bogged down in weird supernatural tangents, which works nicely in Aria but is a bit weird in Amanchu. Still, they are both fantastic series if you want to relax and enjoy the weather so to speak. They are about taking it slow and learning about yourself and others through your environment. read more 

It's quite clear that both these anime have the same director/author because of the atmosphere, setting, character, pacing, ost and in general pretty much everything feels similar. These two anime series are a great example of slice of life, and while Amanchu shows a more real life example, Aria sure has its own strong points in this area. So if you liked one of this series, you can bet you'll also like the other!  

Aria and Amanchu! are both works of Amano Kozue. The animation is quite similar and both are Slice of Life anime. They share the same calm and relaxing atmosphere and have a female character with a particular passion as the main protagonist. Nature (especially water) and friendship are strong themes in both Aria and Amanchu!. 

Cast of quirky but cute girls with activity connected to water and their enteritaining interractions. Both by the same author. 

Both series have a relaxed, sometimes whimsically magical atmosphere, with a strong focus on personal growth, interpersonal relationships and the passing of time. Lots of water in both, and similar music. 

Just by watching one episode of each show you should be able to tell that same person is author of their source material. These are some of the most relaxing shows which focus on activities relating to water. Main difference between these shows is their subject where Aria is focused on Gondolas while Amanchu is focused on scuba diving.  

Two slice of life anime adaptations of Kozue Amano's mangas, both directed by Junichi Satou as well. They both show the characters as a cute chibi form of themselves at scenes and are relaxing yet fun to watch. Aside from the splendid environments shown throughout their series, there are some magical aspects too hidden in their landscapes with beautiful moments to behold. There's even a little bit of reference to Aria as well with the characters and casting used in an episode of Amanchu! too. I like to lump YKK, Aria, and Amanchu! together due to similarities in its nature of feel but in its use of composers for their OSTs too. read more 

Both done by the same author "Amano Kozue".Both Amanchu! and Aria are relaxing,related to water(Amanchu is about diving while Aria is about rowing gondolas), and have the same director.The characters are sure not really similar to each other but there are two girls from Teko's flashback who share the similar VA(and somewhat similar appearence) as Aria's Akari and Aika. 

both series are based of a manga by the same artist, they are actually so similar The OST, The characters and the theme of the ocean is shared between the two, If you like relaxing anime give this a try. 

Both made by J.C Staff, 'Amanchu!' and 'Flying Witch' both have the same overarching lighthearted feel. The 'Slice of Life' genre is explored in both and each of the main characters move to a more rural setting, where they meet new people. The art style is comparable in both: highly detailed, brightly coloured landscapes and similar character designs. The main differences lie in the two locations: the seaside in 'Amanchu!' and rural Japan in 'Flying Witch'. The former focuses on diving while the latter combines the supernatural with reality. 

Both give a similar "relax and smile" vibe. Special to begin the day with a calm mind, escorted by great and relaxing music on these pure Slice of Life calmness. Away from the city's dizziness and acoustic pollution. Amanchu! is located on the coast while Flying Witch is on the countryside. Amanchu! is bit more cartoonish. 

If you liked the calm atmosphere and the soundtrack of Amanchu, I recommend you see flying witch, both are from the same producer studio and have good animation quality. 

ZZZzzzz.......Zzzzzzz.....ZZzz.....OH! Sorry! I kinda fell asleep there! Both these titles are just so relaxing! Do you want to relax too? Then you gotta give both these titles a try! --- Flying witch is well about a flying witch! Sounds exciting right?! NO! It's slice of life! It's about a witch. Living a mundane life. I bet it doesn't sound exciting......but i bet it sounds a bit interesting no? There is not a lot of magic here, but there's is a lot of normal mundane activities! --- Amanchu! Don't let the exclamation in the title fool you! It revolves around the female lead exploring her first experiences of scuba diving. Nothing serious! You can put your brains on autopilot and watch this. It also noteworthy to mention how clean the animation is, the use of colors are almost pastel like, it's even soothing to look at.  read more 

If you're looking for a soothing iyashikei series about the small wonders of life, look no further than Amanchu! Amanchu! like Flying witch, follows some a young girl moving to a new town and coming to terms with life in this environment. Despite her anxieties, she gradually comes out of her shell and learns to appreciate her new life, through the friends she makes. 

Amanchu! is a very laid-back, heartwarming, and sweet show. It is one of the only shows I've watched that gave me the same feeling I got when I first watched Flying Witch. 

Similar staff. Both are slice of life school comedy. Very similar atmosphere and plot flows. 

Both series primarily follow a few high school girls as they find out more about themselves and grow (in terms of personality, interpersonal skills and other skills related to their respective passions). Both are lighthearted slice-of-life series with a fair share of introspective moments. Hikari (nickname: Pikari) (Amanchu!) is very similar to Norie (Tamayura) in that both are very energetic girls who already have a passion in life (deep sea diving and making desserts, respectively). The single-mindedness and focus that Hikari has for diving is perhaps more comparable to the passion that Fuu (Tamayura) exhibits for photography. Meanwhile, Futaba (nickname: Teko) (Amanchu!) and Maon (Tamayura) are very similar in terms of their shy personalities and introverted nature. Like the main characters in Tamayura, Futaba seems to gain more confidence over time.  read more 

slice of life with young school grils' extra curicular activities involving traveling 

Together they are the most peaceful animes I know 

If you'd like some slice of life comedies about scuba diving, then here you are. Major difference is that while Amanchu is more relaxing and wholesome, Grand Blue is more, well, crazy. 

If you enjoy anime that show the beauty of the deep blue sea, then these two are definitely for you. They also have a lot of comedy used in different ways to show off how great the chemistry is between the characters.  

cute boys and girls doing cute things type of series with a cast of quirky weirdos, summer vibe, pretty sceneries and water activities. 

If you enjoyed Aria, you'll probably also enjoy Amanchu. - Both of them were directed by the same person, Junichi Satou. - Both anime have the same mood, being a slice of life without much happening most of the time, but whose characters easy to like and get involved with. - They are both also set in a quiet and happy town, and people go there explicitly to travel in the sea (in Aria's case, it's above water, in Amanchu's case, it's below water). - Amanchu has Aria references popping out from time to time, including "pseudo-cameos" of characters that are really similar to Aria's main characters and have the same voice actresses. Overall, if you liked one it's hard that you disliked the other. If you've not watched either, I'd recommend to watch Aria (in order) first, since Amanchu has a some [s]fanservice[/s] references that would be lost without having watched at least one Aria season beforehand. read more 

The most notable connection between these two shows are the green haired main characters - free spirited airheads almost to the point of being annoying. But in the end they're everyone's friend. Don't forget about swimming and the sea! Amanchu has a swimming club; Umisho a swimming club. A lot of splashing around happens in the ocean. However, Umisho is more focused on comedy and pervy scenes whereas Amanchu on friendship and slice of life.  

First time I knew Aquatope from a mutual I was thought that this anime will have many Amanchu vibes,, and my thoughts were right. Both Amanchu and Aquatope set in coastal Japan and tell about a girl that moved from Tokyo for a better life and meet a local girl that will be her best friend there. The only differences are Amanchu set in Izu, Shizuoka when Aquatope set in Okinawa; also Aquatope is an original anime when Amanchu is an adaptation from the manga
