Last updated: 2026-09-04

Nachster Energy Co., Ltd. (“we”) complies with Japan's Act on the Protection of Personal Information and related legislation in operating its AI infrastructure business, Nachster AI, and handles personal information as set out below.

1. What we collect

We collect personal information in the following circumstances.

• When you contact us through the enquiry form on this site or by email — company name, contact name, email address and the content of the enquiry.
• Information you provide in meetings, when entering into a non-disclosure agreement, and during the proposal and contracting process.
• Information arising from operational correspondence and support while you use the service.

This site uses no analytics tooling and no advertising cookies. On the server side, connection logs — IP address, timestamp, requested path — may be retained for a limited period to monitor availability and maintain security.

2. Purpose of use

• Answering your enquiry and making technical and commercial proposals.
• Entering into and performing agreements, and operational correspondence thereafter.
• Providing, maintaining and improving the service.
• Checks required by law, including export control and related regulation.

We obtain your consent before using personal information for any other purpose.

3. Disclosure to third parties

We do not disclose personal information to third parties without your consent, except where:

• disclosure is required by law;
• it is necessary to protect life, health or property and consent is difficult to obtain;
• we are cooperating with a public authority in the performance of its statutory duties.

4. Processors

We may engage third parties to process personal information as far as necessary to achieve the purposes above — data centre operators, operations partners and providers of business systems, for example. We exercise necessary and appropriate supervision over them.

5. Security measures

We take necessary and appropriate measures to prevent leakage, loss or damage of personal information, including access-rights management, retention of operation records and staff training.

6. Access, correction and suspension

We respond, as required by law, to requests from you for disclosure, correction, addition or deletion, suspension of use, erasure, or suspension of third-party disclosure of retained personal data. Contact the address below; we will verify your identity before acting.
