"Many parts of India still face the problems of discrimination and a major social stigma is attached to those afflicted with leprosy. After meeting and understanding them, one thing I can conclude is that the leprosy situation in India needs help," Sasakawa said.
Despite the fact that most of them are cured, they and their families are forced to settle in separate leper colonies in India.
"Necessary support should be extended to the leprosy-affected people and their families to change the scenario," he added.
The Japanese delegate was on a tour of the leper colonies Tuesday at Asansol in Burdwan district of West Bengal.
He was accompanied by Member of Parliament Dinesh Trivedi, who is currently the convenor of the Forum of Parliamentarian to Free India of Leprosy.
Residents of the Rahmatganj and Kankardanga leper colonies at Burnpur in Asansol sub-division -- home to 159 families -- mainly resort to begging, and collecting rags and scrap to make ends meet. Many also work as masons.
Many districts in India continue to report cases of leprosy higher than the WHO benchmark for elimination of leprosy. A total of 1.35 lakh new cases were detected during the year 2012-13 in the country, according to National Leprosy Eradication Programme data.
In West Bengal, 11,683 new cases of leprosy were reported between April 2012 and March 2013. The annual new case detection rate in nine districts (out of the total 19 in the state) is more than 10 per 100,000 population.
Burdwan reported 1,293 cases in 2012-2013.
"We aim to provide them a life with dignity, better education for their children, pension for the elderly and ensure them acceptance into the society," said Sasakawa, who in 2006 established the Sasakawa-India Leprosy Foundation in India.
