My name is Nishikawa. I work as a freelance writer. Due to the nature of my job, my income is unstable, so since last year, my wife Yui has been working as a temporary worker. She works full-time, Monday to Friday, as an office worker at a company in the city. One day, I was asked to write an article on the topic of "Heisei Japan's Social Inequality," which has been a hot topic in recent times, and I decided to go around and interview people about the reality of the gap between regular and non-regular employment.
