Announcement reposted from Amazon Japan:
Effective November 20, 2024, our Sale Price Settings policy will be updated to provide more clarity on the legal requirements for setting sale prices. We’ve added relevant government guidelines to help you comply with the Act against Unjustifiable Premiums and Misleading Representations, and we’ve made updates to help you better understand the applicable laws and guidelines of the Consumer Affairs Agency.
