In partnership with like-minded organizations, Tansa has created the following databases to give the public easy access to information disclosed by the government and corporations but which is not compiled in a single location.

Unfortunately, our databases are only available in Japanese. Please get in touch at if you would like assistance.

Money for Docs

Japan’s pharmaceutical companies pay significant amounts to research institutions and doctors in the form fees for research, lectures, consulting, article-writing, and other activities. In line with industry guidelines, pharmaceutical companies must disclose such payments. However, there was no way to see overall trends, such as the total amount received by a single doctor from various companies or which medical fields experienced the greatest numbers of payments.

Our Money for Docs database, created in partnership with the Medical Governance Research Institute, compiles and makes easily searchable payments from pharmaceutical companies across Japan.

(Japanese only)


Japan’s national budget has increased dramatically in the past decades, from 60 trillion yen (about $550 billion) in 1989 to over 100 trillion yen (about $930 billion) in 2018. Where is the money coming from, and where is it going?

In partnership with policy think tank Japan Initiative, data visualizer Visualizing.JP, and Professor Yosuke Onoue’s lab in Nihon University’s Department of Information Science, Tansa created the Judgit! database to allow citizens to check how the government is using their tax money by compiling the budgets for around 5,000 government projects.

Fukushima Timeline Project

In 2016, five years after the 2011 triple disaster, Tansa (while it was still a project of the Waseda University journalism institute) created a timeline of the Fukushima nuclear accident, including levels of radiation emitted from the damaged plant. The database was released as part of “The Wave of Reconstruction,” a project by Italian journalists. It was also a finalist for the 2016 DIG Awards and appeared in the Italian magazine Internazionale.
