Thank you for your interest in contributing to the Yahoo! JAPAN’s OSS product (the “Product”). Yahoo Japan Corporation (“Yahoo!”) is very interested in receiving Your Contribution (defined below). In order to participate, we need to confirm how the rights in Your Contributions will be handled. Following the practices of other open source communities, Yahoo! requests that you grant Yahoo! a license, as indicated below, to the intellectual property rights in Your Contributions. Yahoo! requires that you have a Contributor License Agreement (“CLA”) on file prior to using any of Your Contributions. This helps us ensure that the intellectual property embodied within the Products remains unencumbered for use by the whole of the community.

Please review this CLA. By submitting Your Contribution, you accept and agree to be bound by the terms and provision of this CLA.

Please read this document carefully before signing and keep a copy for your records.
