Daigo Sato, the man who founded the NPO that set up Japan's first political internship program, Dot-JP, 10 years ago, has embarked on a new mission this year to help the nonprofit organizations themselves.

In May, Sato established Charity Platform, the first NPO in the country to act as an intermediary for other NPOs. His aim is to help the more than 35,000 NPOs in Japan raise funds by linking them with companies looking to contribute to society.

"Since 1998, when the first NPO law was enacted, the number of NPOs in Japan has risen to more than 35,000. But I thought these NPOs had done little to change society, and I was wondering whether there were other ways to increase their presence," Sato, 35, said in a recent interview.
