Kemurikusa (TV)

Girl's Last Tour and Kemurikusa take place in a very similar setting, a gray, post-apocalyptic, desolate, and very far into the future wasteland of sorts. If you are interested in mysterious landscape that makes you curious to see what could happen next I would highly recommend both shows. 

Kemono Friends and Kemurikusa are similiar in almost every aspect. Both will give you the same vibes, albeit Kemurikusa is dark from the beginning, while Kemono Friends only by the end. Anyway, both of them: - are directed by Tatsuki and produced by Yaoroyozu - have quite different, yet still post apocalyptic setting in which all humans mysteriously vanished - main character is the only known human, who noone knows how he ended where we meet him (even himself/herself) - both are accompanied by anthropomorphic creatures (animals in Kemono Friends, plants in Kemurikusa), who accompany our MC on adventure - using the very similar 3D CGI animation, which by many is considered as bad, but in fact is th charm of those shows - the antagonists are non-sapient, hostile entities (bugs or "mushi" in Kemurikusa, Ceruleans in Kemono Friends) - both received pretty bad reception early on read more 

both feel like you're watching an adventure RPG walkthrough. both play on a contrast between cute child-like character designs and a cruel dangerous world around them, with some quite gruesome scenes. in both, one of the cast is an amnesiac who seems to hold the key to the mystery that awaits at the final destination of their journey. 

the same action adventure genre where it involves guy finding himself in alternate world were survival is the name of the game. 

Both involve a group of people traveling on a train to a destination in a post apocalyptic world. 

It amazes me that no one has made this recommendation. Both shows portray a dark, gloomy yet beautiuful post-apocalyptic world filled with mysteries. We also have female leads acting as a tsundere (and they're not annoying at all! I like them a lot). However, please notice that romance is a subplot so don't expect anything sweet.  

One of few series where trees take active role in the plot. 

Both series is set in an (post) apocalyptic world, where human society has been destroyed. Both series shares a 'roadtrip' style boy meets girl love story narrative where a mentally depressed meta-human girl connects with a human boy with extraordinary powers to fight off giant mechanical enemies powered by biological energy (?) Both cast of Kemurikusa and Hanoka shares a 'Leaf' motif. Both series seems to shares a significant inspiration from the works of Hayao Miyazaki, especially Naussicaa of the valley of the wind. Both series utilises Indie-animation quality CGI, since both Tatsuki and Morino inherited their style from their amateur backgrounds of Japanese Web Animation. Both Series are based on the creator's web animations, in some ways. Both series is backed up by a producer who is planning to kick-start the new methods of creating anime. Last but not least, both creator has participated in the majority of roles, technically making both anime being made by 'one people' with several backups The major difference is that, Kemurikusa is a complicated yet interesting series, whilst Hanoka is a cliched sci-fi war story with abysmal flash animation and voice acting. read more 

Both series are set in a destroyed future with giant objects where old robots try to kill you. 

Both are shows about a robot(s) and a human in a post apocalyptic world with kind of janky visuals but endearing characters. 

In both anime the protagonists are experiencing an apocalypse, while living on a train and going around exploring the world and trying to survive from weird beings 

Kemurikusa reminded me of Houseki no Kuni not only in the similar cg art style but also with a very similar feel or aesthetic. Both shows are sci-fi with action and constant mystery and natual curiosity of what their seemingly apocalyptic world has to offer. These shows don't rely on cliffhangs rather intigue the audiance with its diverse cast of characters and interesting world and character building. If you enjoyed the aesthetic of one show I would highly recommend the other. 

Both feature post apocalyptic settings that are very well built and fleshed out through environmental storytelling. Kemurikusa is much more lighthearted, but both evoke similar emotions. It's a pleasure to learn about their worlds through clever storytelling.
