Yen for Docs Database

Achievements so far

Achievements over four years

Our public database discloses the payment data from pharmaceutical companies for four fiscal years (2016 to 2019). In 2019, the Ministry of Education, Culture, Sports, Science and Technology used this database for its survey. As a result, they announced that there were seven university professors who earned more than 20 million Japanese yen in 2016, and they expressed their intention to ask the National Diet to require universities to review their regulations on dual employment and ethics.

The following are the reports and research we have conducted using this database.


  • In 2016, 110 doctors received more than 10 million Japanese yen annually in honoraria and other payments from pharmaceutical companies, totaling 26.6 billion yen. (June 8, 2018)
