Privacy & advertising
Advertising
This website uses Google AdSense to display advertisements. Google and its partners may use cookies or similar technologies to select, personalize and measure ads, prevent fraud and improve their services.
Advertisement areas are labeled “Advertisement” and visually separated from editorial articles. The English edition does not display Amazon.co.jp affiliate product cards.
Information stored in your browser
We use a cookie to remember your language and local storage to remember which articles you have liked. You can remove them in your browser settings. Likes are counted without requiring an account.
To limit the introductory card to your first three visits, local storage also keeps a visit count, the last page-view time, and whether you dismissed the card or opened the collection. This display setting stays in your browser and is not sent to our server.
Analytics and external services
Our production website uses Google Analytics to understand usage and improve the site. Google may receive cookie identifiers, device/browser information, page views and interaction information. Analytics is disabled in our preview environment.
Cloudflare delivers and protects the website and may process connection information such as IP addresses and request logs for delivery and security. The administration and preview sites use Cloudflare Access for authentication.
Loading third-party images or embeds, or opening external links, may transmit your IP address, browser information and referring page information to the provider, such as YouTube or X. Their own privacy policies apply.
When an advertisement is loaded or selected, Google and its advertising partners may receive identifiers, device/browser information, IP address, page information and interaction data. Their own privacy policies and consent requirements apply.
