Japan Trip Tools does not require an account and does not collect personal information to operate the tool. Your trip dates and area selections are processed entirely in your browser and stored only in the page URL (so you can bookmark or share a result) — they are not sent to or stored on our servers.
We use Google Analytics 4 (GA4) to understand aggregate usage (for example, which events, areas, and date ranges are checked, and which affiliate links are clicked). GA4 uses cookies and may collect standard technical data such as your browser, device type, and approximate location via IP address. This data is used only in aggregate to improve the tool; we do not use it to identify individuals. You can opt out of Google Analytics tracking using the Google Analytics Opt-out Browser Add-on.
Outbound links to booking partners (Agoda, Booking.com, Klook, KKday, etc.) may set their own cookies once you click through, governed by their own privacy policies. See About for our affiliate disclosure.
