'Space Brothers' is based on the manga by Koyama Chuya, serialized in 'Morning' (Kodansha).

【Work Overview】

<INTRODUCTION>

In their youth.

Two brothers, Mutta and Hibito, made a promise under the stars to become astronauts.

Then, in 2025.

Younger brother Hibito, chasing his dream, becomes an astronaut.

Selected as the first Japanese crew member for a lunar mission, Hibito gains worldwide attention.

Meanwhile, older brother Mutta, working at a Japanese car manufacturer, gets into a fight with his boss, delivers a headbutt, and is promptly fired—sent back to his hometown in disgrace.

At that moment, Mutta receives an email from Hibito.

"Let's go to space together."

Spurred by the childhood promise awakened deep within his heart, Mutta sets his sights on space once again.

Beyond countless rivals and grueling exams—just wait, space!

The younger brother, an astronaut. The older brother, unemployed.

The younger brother fulfilled the promise. The older brother remembers it.

The story of the 'Space Brothers' begins, aiming for the promised sky.
