We do not disclose personal data to third parties without your consent, except in the following cases.

To improve the experience and understand usage, this site transmits data to the following external services. (In Japan this disclosure is required by the external-transmission rules under Article 27-12 of the Telecommunications Business Act.)

• Microsoft Clarity (recipient: Microsoft Corporation, United States) — sends scroll and click positions with an anonymous identifier. Purpose: improving the user experience.

Neither includes information that identifies you, and we do not link this data to an individual ourselves. You can disable cookies in your browser, though some functionality will stop working. See the cookie policy for details.

We entrust the handling of personal data to the processors below, to the extent necessary to achieve the purposes above. Each maintains appropriate safeguards, and we are responsible for selecting them and supervising how they handle the data.

By submitting a form or otherwise using this site, you are taken to consent to the provision of personal data to these processors, including recipients located outside Japan. If you do not consent, please do not use the forms.

To prevent loss, damage or leakage of personal data we apply the following measures.

• Encryption in transit (HTTPS / TLS)
• Database access restricted to the minimum necessary (service role only)
