If you liked the Welcome to the NHK! anime, the Anime-Planet community thinks you'd like:
Meet Tanaka Oji: lead guitarist of a hard rock band in his youth, now an aging salaryman who has all but given up on his old dreams. Trudging through a boring day-to-day life, he gets a rude awakening when his musical talents are once again called upon — to save the galaxy from invaders, no less... but with age come responsibility; he has a family to look after and can’t just give up his day job, no matter how hot and blonde the reason. The time has come for a decision; will he once again try to live out his dream and rebel, or conform to the demands of society?
Black Heaven and NHK are stories about men who are stuggling to get a hold of their lives. In Black Heaven, it is more of a midlife crisis, while NHK is a struggle to confom to society - and in Black Heaven, it's almost a struggle against it. The shows are similar in their mature and realistic approach the the characters' lives, while still having plenty of comedic absurdities.
Summer break is now over; the second semester has started for Tomoya, Nagisa and the others, and little has changed. Since Tomoya's relationship with his father is still troubled, he continues to live with Nagisa and her family, even if it means getting roped into organizing a baseball team for the family bakery. Life at school continues as normal with Sunohara as carefree as ever; however, when his sister Mei voices her concerns about him, the series of events that follow place a strain on Sunohara and Tomoya’s friendship. Whether it's saving a person from themselves or passing on a message from the past, one thing’s for sure: no matter how tough things get, good friends will always be there to help out.
While from the outside it might look like Clannad: AS and Welcome to the NHK! don't have much in common aside from shared genre traits, I think both animes do go well with eachother; both are very emotionally charged animes with some times of comic relief. Both animes have a very strong story that covers a lot of serious and often times relatable themes that aren't always cheery. Where Clannad and the After Story cover the love intrest in more of a open way that HNK, and NHK deals a lot with social issues like anxiety, I'm sure whether your new to this kind of anime or a seasoned Romance/Drama buff, if you enjoyed one you'll enjoy the other!

Now, in addition to enduring his aunt’s energetic attention and flirting awkwardly with the girls in his class, Makoto finds himself drawn into helping Erio rejoin regular society and stopping her 'alien' antics.
In the year 2010, on a day called ‘Careless Monday', ten missiles hit the cities of Japan; miraculously, there are no casualties and the event quickly fades from public memory. Some time later, Saki Morimi decides to visit Washington, DC on her graduation trip to America, but that day begins a series of bizarre events. After getting into trouble with the police, she's rescued by a young man who is completely naked save for a gun in one hand and an even stranger item in the other - a phone credited with 8 billion electronic yen and a female voice on the other end called Juiz who will fulfill his every wish. Having no recollection of his past and calling himself ‘Akira Takizawa', the young man accompanies Saki back to Japan in the hopes of discovering who he is. Akira's enigma quickly proves fascinating and Saki decides to help him rather than reunite with her family; but what neither realizes is that Akira is embroiled in a dark game of life and death linked to the Careless Monday missiles. Has Saki just made a terrible mistake, and can Akira unravel his own mystery before they both lose everything?
Both of these shows are beautifully animated, involve conspiracy theories (though to differing extents), and are set in modern day Japan. Of course they both offer a love story, as well as a good mix of drama and comedy.
But the thing that makes these two the most alike is their commentary on current events in Japan, particularly with the age gap and NEET/hikikomori phenomenon.
After proclaiming himself to be the illegitimate son of Prime Minister Iinuma, Akira is in hot water with not only the other Selecaos, but also Chiguse, the Prime Minister’s wife.
