If you liked the Welcome to the NHK! anime, the Anime-Planet community thinks you'd like:
Nishi has been in love with Myon since he was 9 years old. They both had feelings for each other, but due to Nishi's cowardice their relationship never became more than friendship. Now, in the present, Nishi is 20 years old and aims to be a great manga artist; but he still loves Myon. After years of being apart they meet again, but she tells him that she's thinking of marrying her boyfriend. Nishi is still a coward so he accepts it and wishes her luck. While they're talking at her older sister's restaurant a pair of yakuza walk in looking for their father. One of the yakuza starts harassing Myon and out of anger Nishi chooses to finally take a stand -- but he is shot and dies. Now, in limbo, he chooses to live again; but will he really live any differently than before?
Tragically funny and affecting, both Welcome to the NHK and Tatami Galaxy manage to capture the self-destructively gauche young male who struggles to fit in with society for one reason or another. More importantly, both shows manage to represent the humour in their misadventures while not completely sidelining the human tragedy that underlies it all. One show reminded me powerfully of the other and I think fans of one will find a lot of enjoyment in the other.
After having lived elsewhere for several years, Sana returns to the town in which he grew up in, and quickly begins to reacquaint himself to his surroundings and new high school. While there, Sana runs into his four childhood friends: Shuu, Shuri, Aoi, and Nanaka; but for some strange reason Nanaka gives him the cold shoulder. As he goes about his new daily life, can Sana rebuild his friendship with Nanaka while trying to deal with a troubling secret from his past?
In the future, a devastating event known as Second Impact has destroyed Tokyo as we know it, giving rise to Tokyo III - a city under siege by mysterious lifeforms known only as Angels. Mankind's only line of defense are the Evangelions, a set man-made machines piloted by a trio of fourteen year-old teenagers, Rei, Shinji, and Asuka. The fate of Japan and the entire world now lie with these three children, though they might not have the power to save the most important thing of all: each other.
In both series, all the characters have huge mental problems and most of the plot is about getting over them. Welcome to the NHK is a little less subtle about this, given its comedic value, but I think it would still translate well.
The studious and uptight Chiaki is well-known as the top pianist of his school, and dreams of becoming a world-class conductor like his idol, Viera; but his fear of flying (which makes studying abroad impossible) combined with a recent break-up and dismissal from his piano instructor causes that future to seem both bleak and unlikely. After collapsing outside of his apartment, drunk, Chiaki inadvertently meets a young woman named Nodame who, while quite talented at the piano, is unclean, clumsy, and haphazard. Despite being almost polar opposites, the two begin to grow closer and work, together, to overcome the obstacles in their careers.
Nodame Cantabile and Welcome to the NHK! are exciting roller-coaster comedies about the developing relationship between two character archetypes: a cool, standoffish guy with big dreams; and an upbeat, quirky girl with a painful past. This fateful relationship eventually leads to the odd couples' bring out the best in each other and overcoming of their personal weaknesses. Even though Nodame is very light-hearted and NHK is distinctively darker, the two are comparable in its use of characterization more than slapstick to achieve laughs. Both shows are delightful and even surprisingly moving when dealing with the couple's relationship.
Ouran High is a school for the extremely wealthy or, in Haruhi's case, the extremely talented. But no amount of talent will help when Haruhi accidentally drops an eight million yen vase in a music room. The vase was the property of Ouran High School Host Club, a group of attractive young men who, for a fee, provide their time and affections for their lovesick clientele: the female students. Fascinated by this strange new specimen, a poor and clumsy commoner, they force Haruhi to work for them until the debt is repaid; but they get a lot more than they bargained for...
Just like NHK's occasionally paranoid Sato, Ouran's male lead, the charming Tamaki Suoh, often has moments in the series when his imagination is kicked into overdrive and causes him to spazz out. If you like characters with runaway imaginations, then watch Ouran High School Host Club.
