In your browser

In your browser

  • No sign-up or login is needed; the site has no accounts.
  • Maps and 3D terrain are drawn, and the 3D white map editor builds and exports models, inside your browser.
  • Map, terrain and feature data are loaded by your browser directly from each provider, such as the Geospatial Information Authority of Japan (GSI). Those providers therefore receive the location of the area you are viewing.
  • Work in progress in the 3D white map editor is saved automatically only inside your browser. Your work is not sent to this site’s servers (to count exports, only the name of the exported format is sent).
AI feature

The AI feature

  • “AIで探究” (Explore with AI) uses Google’s generative AI (Gemini). Your question is passed through this site’s server to that service, and its reply is shown on screen.
  • This site does not store the conversation; it disappears when you reload or close the page.
  • Choosing 中学生 (junior high) or 高校生 (senior high) changes the wording of the replies.
  • Please do not enter anything that identifies a person, such as names or school names.
  • The AI feature’s screen and replies are currently in Japanese only.
