In the second story of Episode 6 of Hinamatsuri, Anzu and the tramps who 'adopted' her being kicked out of the park where they lived. Those tramps are quite kind, at least seem so in the anime. They don't seem to have any mental illness or addiction, and they are not very lazy-they pick cans to cover their living.
Why don't the tramps seek help from the welfare system? Wouldn't it be better if they are provided shelter? Why do they choose to tramp around the city?
I read in some novel that some tramps in America refuse to live in a welfare shelter because they don't want to leak out their personal information or be seen as animals, which would make they lose their dignity in their eyes. I wonder whether the tramps in Japan hold the same opinion.
