An ongoing photo exhibition in Tokyo illustrates a burning desire of people living on the streets: to simply build normal relationships with the rest of society.

The Tokyo Metropolitan Human Rights Promotion Center currently displays 42 photos of the homeless, taken by freelance photographer Hideaki Takamatsu, who began the project out of curiosity about how the homeless live.

Takamatsu started shooting photos of the homeless in 1994, when he attended a photography school after graduating from college with aspirations of becoming a photojournalist.
