Privacy policy

Japan, Solved. is designed to be useful without asking visitors to create an account or provide personal information. This policy explains what may be processed when you browse the site or contact us.

Information you choose to send

If you email us, we receive your email address and the information included in your message. We use it only to respond, investigate corrections, or handle the request you sent. Please do not email passport details, payment information, or other sensitive personal data.

Basic technical information

Our hosting provider may process standard request information such as an IP address, browser type, requested page, date and time, and security signals. This information is used to deliver the site, prevent abuse, and maintain reliability.

Cookies, analytics and advertising

The site does not currently require an account or set its own marketing cookie. If Google AdSense or an analytics service is enabled, this page will be updated before or when that service becomes active.

Advertising providers such as Google may use cookies, web beacons, IP addresses, or similar identifiers to deliver and measure ads, limit repetition, prevent fraud, and—where permitted and consented—to personalize advertising. Third parties may place or read cookies in your browser as a result of ad serving. Learn more about how Google uses information from partner sites and manage Google ad choices through My Ad Center.

Where legally required, visitors will be shown an appropriate consent message before advertising or non-essential analytics technologies are used.

External links

Guides link to transport operators, government agencies, booking services, and other websites. Their privacy practices are governed by their own policies, not this one.

Data retention and requests

Email correspondence is kept only as long as reasonably needed for the request, editorial record, or legal obligation. To ask about information you sent us or request its deletion, contact [email protected].

Changes to this policy

We may update this policy when the site adds analytics, advertising, email tools, or other services. The date at the top will show the latest revision.
