Privacy Policy

Personal information

When needed to respond to an inquiry, we may collect information submitted through the contact form, such as a name, email address, and message. We use it to respond, make necessary contact, and prevent misuse. Except where required by law, we do not provide it to third parties without consent.

Contact form

Contact form submissions are sent to the site operator by email through Cloudflare Pages Functions and Cloudflare Email Service. Do not include sensitive personal information, passwords, or payment information.

Analytics and language preference

We use Google Analytics to understand site use and improve content. It may collect information such as visited pages, device environment, and referrers through cookies or similar technology. Google handles this information under its Privacy Policy.

You can disable Google Analytics measurement through your browser cookie settings or the Google Analytics Opt-out Browser Add-on.

We also use TALPA analytics, which may collect visited URLs, referrers, page titles, and a browser-stored identifier to understand site use and improve content.

The language notice and switcher store only the selected language code (ja or en) in localStorage. They do not use cookies, IP addresses, or region detection, and blocked localStorage does not prevent access to the site.

Advertising

We use, or may introduce, Google AdSense. Third-party vendors including Google may use cookies, including advertising cookies, to show ads based on previous visits to this and other sites. You can manage personalized ads in Google My Ad Center.

External links and disclaimer

Links to external sites, including advertising and affiliate links, may appear on this site. We are not responsible for information, services, privacy practices, content, or safety on linked sites. We aim for accuracy but do not guarantee completeness or fitness for a particular purpose, and accept no liability to the extent permitted by law for damages arising from use of this site.

Copyright and policy changes

Unless stated otherwise, rights in original text and images belong to the operator. We may revise this policy in response to changes in services or applicable law and will announce material changes on the site.
