On our mail magazine's register/unregister page, we request email addresses in order for us to begin providing, or cancel, distribution service for the magazine. In an effort to prevent "imposter" registration by a third party, we also ask for names and affiliations, which we use to send a confirmation message to the individual at the time of registration for the magazine. The individual is registered after replying to this confirmation message.
We do not use personal information that we receive for any other purpose than contacting this website's users or to analyze in order to improve the site's contents. In the event that it should become necessary to use personal information for a purpose that goes beyond these limits, we will inform the users of this website in advance of our intention to do so.

when we are required to release the information by law, decree, etc.
when there is an urgent need to release the information in order to protect a person's life, physical well-being, or important personal interests such as property
We keep an access log to record the access conditions (time of access, IP address, host name, browser, etc.) of those who use this website, but this is not information that can be used to identify specific users. We analyze the access log in order to improve the site's contents—we do not use it for any other purposes.
