On a fateful summer night in 2006, Mutta Nanba and his younger brother Hibito witness what they believe to be a UFO flying toward the Moon. This impressing and unusual phenomenon leads both siblings vowing to become astronauts, with Hibito aiming for the Moon and Mutta, convinced that the eldest brother has to be one step ahead, for Mars.

Now an adult, life hasn't turned out how Mutta had pictured it: he is diligently working in an automotive company, whereas Hibito is on his way to be the very first Japanese man to step on the Moon. However, after losing his job, Mutta is presented with an unexpected opportunity to catch up to his younger brother when the Japanese Aerospace Exploration Agency, commonly known as JAXA, accepts his application to participate in the next astronaut selection. Despite self-doubts about his prospects, Mutta is unwilling to waste this chance of a lifetime, and thus embarks on an ambitious journey to fulfill the promise made 19 years ago.

At first glance Space Brothers seems to be an anime about two brothers that just go space and do astronaut things, but oh ho, dear reader, it is so much more than that. It is a realistic journey delving into one of the most difficult professions ever conceived by man. Now that the series has concluded [for the time being], a proper review is in order. But first, we better shake hands.

Space Brothers cleverly depicts the pursuits of Mutta and Hibito, converging their storylines at some times and following them separately at others. This structure is beneficial to the flow and progression, and earns read more

"An older brother must step ahead against his younger brother" - Nanba Mutta.

Lately, i haven't found any good anime to watch.. then i meet Uchuu Kyoudai/Space Brother, at the first i was like oh just an average anime which have sci-fi and bla bla bla. since i didnt have any anime to watch, i thought i could try it for just one episode. and then seems like i had learned my lesson.

"Dont ever judge anime by its cover, genre, or anything else before you watched it" - Me, after watching this.


The story was simple, its about Nanba Mutta as the older brother who had promised read more

You are probably wondering why I gave this series a perfect 10 even though I've only seen 10 episodes so far...

Well, simply put, everything about this anime feels very authentic. Real. There is no sense of false pretense. And above all, it gives off a very contagious sense of hope and optimism. A sense that your dreams ARE reachable, and that there is no such thing as bad luck; it's all about making your own luck.

I'm sure everyone has had their share of disappointments and somewhere along the line, has felt bitter about the way their life turned out. I'm also sure that everyone read more

Uchuu Kyoudai... well I have to day that this anime is one of those inspiring ones.

I first started watching the first four episodes of this anime at AX (Anime Expo 2012) with no hopes for this anime but oh boy... I was proved wrong. Throughout my life I always watched shoujo, shounen, mecha, adventure etc.

From the fact that I only considering watching those genres it came to my judgement when it I was watching Uchuu Kyoudai at AX.

As human beings, everybody
DO NOT JUDGE A BOOK BY IT'S COVER! ~Lesson learned~ -.-

Uchuu Kyoudai (Space Brothers in English) was obviously not one of those animes that read more
