Section 1 (Membership, Changes and Termination)

To use the Service, the Member must enroll its membership by completing the prescribed process. Upon completion of the application process the Member shall be able to use the Service using the method designated by NetAdvance.
Membership of the Service is limited to those who have paid for the contents (who have purchased the image data).

The Member shall provide NetAdvance with true information required for enrollment, such as the Member’s name, address and e-mail address. NetAdvance may refuse the Member’s enrollment, or terminate the Member’s enrollment even after NetAdvance accepts the Member’s enrollment

(1)	if any information provided to NetAdvance at enrollment is found to be false, incorrect or omitted;
(2)	if the Member has violated any of the Terms of Use in the past;
(3)	if the Member has ever been subject to temporary suspension or termination of the enrollment to the Service;
(4)	if NetAdvance finds it inappropriate to provide the Member with the Service for any other reason.

In case any change is made to the Member’s address or other information provided to NetAdvance, the Member agrees to notify NetAdvance promptly. However, changes to the Member or company name require the approval of NetAdvance. IN THE CASE WHERE THE MEMBER INCURS ANY DAMAGE DUE TO LACK OF NOTICE OF CHANGE OF ENROLLED INFORMATION, NETADVANCE SHALL NOT BE LIABLE THEREFOR.
If the Member wishes to terminate its enrollment, it agrees to notify NetAdvance of such termination. IN THE CASE WHERE THE MEMBER INCURS ANY DAMAGES DUE TO LACK OF NOTICE TO TERMINATE ENROLLMENT, NETADVANCE SHALL NOT BE LIABLE THEREFOR.

Section 2 (Use of the Service)

The Member may use the Service for academic use, at any time during the period of continued enrollment as a Member, to search and view the information for which the Content Fee has been paid. However, there may be the case where the access to some information is limited at the request of the copyright owner.
The Member may use the Service and print only one (1) hard copy of the data it views on the Service solely for the Member’s internal use; provided that it may not (i) make further copies or (ii) transfer any data to any third party.
Regardless of Section 2 b, if the Member is an educational institution including a school (excluding any for-profit educational institution), the Member may make such number of copies of any data viewed by the Member on the Service as equal to the number of students who take a course offered by the Member and may distribute those copies to those students, but only to the extent necessary for use of such data in such course; however, that the Member may not do so even in a course you offer if the number of copies of data so used or the extent of said use of the data is significant.
The Member may not use any Service in any manner other than those expressly provided in this Membership Terms.
The Member may allow the Service to be used by individuals (“Users”) to whom the Member allows use of its equipment. However, the Member shall bear full responsibility for the observance of these Terms of Use by the Users.

Section 3 (Static global IP address authentication)

Subscribers may use the Service from their designated static global IP address.
In this case, only users of the local area network having the relevant IP address can use the Service. Subscribers may also use a remote access environment that the subscriber has prepared in advance to allow users authorized by the subscriber to use the Services. However, in either case, the number of users using the Service simultaneously is limited to the number specified by the subscriber.
If the Member wishes to increase the number of simultaneous users, the Member must sign a new User Contract for use of the Service.
In case where the Member enters into the agreement regarding “JapanKnowledge Lib Service”, the Service is available on the platform of “JapanKnowledge Lib Service” (“Integration of the Platform”). In case where the Member requests for the Integration of the Platform, it shall notify NetAdvance in writing of such intention. In case of the Integration of the Platform, the number of the simultaneous access to the Service shall be equal to the one of the simultaneous access to the JapanKnowledge Lib service. In addition, the Member may terminate at any time the Integration of the Platform by notifying NetAdvance in writing of such intention.
In the case that Subscribers use the Service through a reverse proxy, they must do so by authenticating for all Services including in and below the JapanKnowledge domain.

Section 4 (Management and Use of ID and Password)

Subscribers who have difficulty meeting static global IP address authentication may in some cases be allowed to authenticate using ID/PW (a user ID and a password).

In case that NetAdvance issues ID and password to the Member, the Member agrees to bear all responsibility for management and use of the ID and password.
Only the Member may use the ID and password NetAdvance issues to it. The Member may not let any third party use, or transfer or otherwise dispose of to any other party, its ID and password.
If the Member forgets its password, it needs to reset its password promptly. If the Member notifies NetAdvance that its ID and password need to be changed for such reason as unauthorized use by any third party, NetAdvance will invalidate the ID and password issued to it and issue it new ID and password.
NETADVANCE SHALL NOT BE LIABLE FOR ANY DAMAGE THE MEMBER INCURS DUE TO ITS FORGETTING ITS PASSWORD, MISUSE OF ITS ID AND PASSWORD, INSUFFICIENT MANAGEMENT, IMPROPER USE BY THIRD PARTY OR ANY OTHER REASON.

Section 5 (Facilities)

The Member agrees to prepare and install any communication equipment, software, communication line and any other equipment and telecommunication services necessary to use the Service, at its own responsibility and cost.

Section 6 (Service Fee)

As a consideration for provision of the Service, the Member agrees to pay NetAdvance a Service Fee separately provided. The Service Fee shall be composed of an Enrollment Fee (only required at the time of joining), a Content Fee (only required at the time of joining), and an Annual Maintenance Fee (required every year).
Notwithstanding the subsection (a), in case where the Member uses the Integration of the Platform under Article 3c, the Member shall be exempted from the annual Usage Fee under the preceding subsection. Provided, however, that, in case where the Member terminates the Integration of the Platform or the JapanKnowlege Lib service, the Annual Maintenance Fee shall be charged.
Even if the Member uses the Service for less than one year, NetAdvance will not adjust the Annual Maintenance Fee on a pro rata basis.
Except where NetAdvance terminates the Service under Section 10 c., NETADVANCE SHALL NOT MAKE ANY REFUND OF THE ANNUAL MAINTENANCE FEE PAID TO NETADVANCE.
If the Member delays its payment of the Annual Maintenance Fee, NetAdvance shall take measures to temporarily suspend the Member’s enrollment of the Service, and upon prior demand of performance, terminate the Member’s enrollment.
Notwithstanding the terms of this Section, NetAdvance shall exempt the Member from payment of any fee during its trial period.

The content of the Service is, as far as possible, written and supervised by experts, and the Service strives to provide high-quality information to the Member.

If NetAdvance needs to make any refund, NetAdvance will notify the Member by e-mail, but if NetAdvance is unable to make refund for any reason without fault of NetAdvance, such as where NetAdvance is unable to notify the Member at the e-mail address provided to NetAdvance or where the Member does not respond to NetAdvance’s notice, duty of NetAdvance to make refund shall expire after one year from the date of termination of the Service.
NETADVANCE SHALL NOT BE LIABLE FOR ANY DAMAGE INCURRED BY ANY MEMBER FOR MODIFICATION, SUSPENSION OR TERMINATION OF THE SERVICE.
