Nihon Review's AC writes: "Hikikomori is a term that is native to contemporary Japan. Defined literally as “staying indoors”, they are a unique subset in the sphere of social recluses, and is a constantly discussed topic in sociological studies within the country. It goes without saying that finding an anime series that uses this controversial phenomenon as a theme isn’t easy; the only one in recent memory that touches upon such a topic is the dark comedy Sayonara Zetsubou Sensei. But before that came Welcome to the NHK!, a title that not only uses it as a theme, but also competently understands what it’s all about and tells a story with it, eventually becoming a cult classic in many anime circles."
