Since his first year of medical training at the Kyoto University-affiliated Institute for Frontier Medical Sciences, Afghanistan-born Khaled Reshad has worked harder than others to gain Japanese patients' trust.

"I would usually stay at work until 11 p.m. or try to accept patients on weekends," Reshad said, adding he did not think of it as a special service to patients.

When a person falls ill and has to see a doctor, their needs and clinic schedules don't always coincide, so he said "it was natural" that he would work all hours to help them.
