Welcome to the NHK (Novel)
In his mostly autobiographical comic Disappearance Diary, Azuma Hideo notes that in order to maintain an optimistic outlook on life, he’d removed as much realism as possible from his book. Azuma’s dry humour and cartoony art style make what should be a depressing story about a man running away from his responsibilities and living homeless seem rather light-hearted and funny.
Author Takimoto Tatsuhiko, in the afterword to his novel Welcome to the NHK, notes that his book also has a fair amount of autobiography.
