Terms of Service

The ALOS-4/ALOS-2 User Interface Gateway (AUIG4) is a system that offers a variety of online services related to the observational data of the Advanced Land Observing Satellite-2 (ALOS-2) and Advanced Land Observing Satellite-4 (ALOS-4), which are developed by the Japan Aerospace Exploration Agency (JAXA).

These Terms of Use state the terms and conditions under which you may use AUIG4. JAXA Site Policy is applied to matters that are not specified in these Terms of Use.
Please read carefully and ensure you accept these Terms of Use before using AUIG4. To use AUIG4, users must agree to these Terms of Use. You can accept the Terms by clicking to agree to these Terms of Use, where this option is made available to you by JAXA, or by actually using the services. In the latter case, users understand and agree that JAXA will treat their use of AUIG4 as acceptance of the Terms of Use from that point onward.

  1. User Registration
    You need to create a user account to use services made for registered users of AUIG4. User registration is only available if you have a joint research agreement/contract with JAXA. Your user account and password will serve as your login in the service for registered users of AUIG4.
    The items required for AUIG4 user registration are a username and valid e-mail address, in addition to the user's affiliation, country, and telephone number.
    For security reasons, AUIG4 requires you to provide a valid email address that reflects your educational or company affiliation (e.g., @jaxa.jp, @XX.edu, @companyname.com, or @XX.org). If you use an email address from Gmail, Yahoo, or any other free email provider, you may not be able to complete your registration or receive emails from AUIG4. User registration is unnecessary if you only use the service as a guest user.
  2. Privacy Policy
    The Privacy Policy of AUIG4 regarding personal information (e.g., username, valid e-mail address, the user's affiliation country, and telephone number) used for AUIG4 user registration is in accordance with JAXA's "Privacy Policy". For details, refer to "JAXA Privacy Policy". JAXA will not use personal information for any purposes other than those used for AUIG4.
    In addition, please refer to our notice on the EU General Data Protection Regulation (GDPR) for information on handling personal information in accordance with that regulation.
    The use of personal information includes the following;
    • to perform statistical analyses so as to improve design, navigation, and experience of AUIG4
    • to understand and to perform statistical analyses of user behavior and characteristics in order to measure use of the various sections of AUIG4 service to request user participation in surveys so as to improve AUIG4 service
    • to respond to user inquiries
    JAXA may outsource various parts of AUIG4 service to a third party. The parts that may be outsourced include system administration, user management, and help desk operations. The third party will use the registered personal information only to the extent necessary for the outsourced business.
  3. Account and Password Management
    A user is entirely responsible for maintaining the confidentiality of the user's account and password. Users agree that they are entirely responsible for any and all activities that occur under the user's account. JAXA is not responsible for any loss or damage caused by such activities, including unauthorized use of the user account or password by any third party.
