We have added Magic Link sign-in: you sign in simply by clicking the confirmation link sent to your email address. There is no password to manage. You can continue to browse every feature for free without signing in.
Each prefecture’s overview, industry, geography, and history have been restructured with sources attached. The editorial voice has been refined and combined with figures from public data, so the articles read more clearly as longform pieces.
We ingested the locations of stations, ports, airports, and major facilities from the National Land Numerical Information (KSJ) dataset, laying the groundwork for a future “distance to the nearest” display on the municipality pages.
We can now tally anonymized page views and error occurrences internally. No personally identifying information is collected (the items captured are stated in the Terms of Use and the Privacy Policy). We use this to prioritize what to improve.
A dashboard now lets us manage the status of inquiries and requests in one list, so replies are not missed. It is not a feature visible to end users, but it raises the quality of our support.
We fetch the daily high temperature for all 47 prefectures from the Japan Meteorological Agency every hour, and added an earthquake information panel.
We released the detail pages for all 47 prefectures together with a weighted ranking feature.
We released the choropleth map of 47 prefectures × 7 indicators, along with rankings.
