The executive committee for the 12th Manga Taisho awards announced during the awards ceremony on Tuesday that Kenta Shinohara’s Astra Lost in Space (Kanata no Astra) won this year’s award.
The awards are also limited to works published last year with eight or fewer volumes to promote relatively newer works.
The manga ended in December 2017, and Shueisha published five compiled book volumes for the manga.
The manga was also nominated for the 23rd Annual Tezuka Osamu Cultural Prize in February, and also ranked at #3 on the Kono Manga ga Sugoi! male readers list in December.
