Affiliate disclosure

Japanese Edition Guide participates in the CDJapan Affiliate Program. CDJapan purchase buttons marked as affiliate links may earn us a commission from qualifying purchases at no extra cost to you.

CDJapan source citations and official help links remain ordinary links. BOOK☆WALKER links are also ordinary links; we do not currently earn a commission from them.

Editorial approach

Our goal is to identify the correct Japanese edition and direct readers to an authorized source. A store will not be presented as the only valid option solely because it offers an affiliate program.
