Frequently Asked Questions
I found an error in an article. How do I report it?
Please use the form and include the article URL along with the part you believe is incorrect (a figure, chart, or source). Our articles are based on primary sources such as e-Stat (the portal site of official statistics of Japan) and official ministry publications, so we will check your report against those sources and correct the article as needed.
Can I use your charts on my site or social media?
You may quote our charts within the scope of proper quotation under applicable copyright law, provided you credit the Site with its URL and the article title. Unauthorized reproduction, copying, or modification of chart images is not permitted. If you are unsure whether your intended use qualifies, please ask us through the form.
Where does the data in your articles come from?
Our articles are based on primary sources: e-Stat (the portal site of official statistics of Japan), official publications of government ministries and agencies, and public data from international organizations such as the OECD, the World Bank, and the WHO. Each article lists the sources used, when the data was retrieved, and where it can be verified, so readers can check the evidence themselves.
How current is the data? Do you update articles?
Figures and charts are based on the latest official data available at the time of writing. Statistics are revised and updated over time, so articles may differ from the current situation. We review articles when important statistics are updated, but we cannot guarantee that every article is always current. For the latest values, please refer directly to the primary sources listed in each article.
Can I request a topic or dataset for a future article?
Topic requests are welcome. Please send them through the contact form below. Note that we cannot promise to cover every request, as it depends on the availability of official data and on our editorial policy.
Can I commission data visualization or research work?
We accept inquiries about visualizing and analyzing official data. Please contact us through the form with the specifics of your request (target data, intended use, and timeline). We will review the details and let you know whether we can take it on.
Who writes the articles?
Articles are narrated by Kaede, and the Japan in Data editorial team takes responsibility for the content and the accuracy of the data. For details on our team and editorial policy, please see the About Us page.
