Tamura credits the success of his novel to his ‘admittedly poor literary skills’, for as a 28-year-old he was able to write like an eighth grader. The simple language, excessive use of exclamations, bold type and cartoon drawings are reminiscent of an adolescent’s diary in the days before blogs. Freedman claims that the success of Diary of a Wimpy Kid was due to writing in a similar style to Homeless.
Freedman comments on Homeless use of cross-media marketing pioneered by Crying Out Love, In the Center of the World. She notes that "all versions of Homeless Junior High School Student use Osaka dialect, and almost every artist and actor involved was from Osaka." The children's book was marketed through the use of the obi strip as being "full of affection for parents", framing the "importance of home and family" in homeless narratives.
