Updated on 5 February 2009 to reflect HMV Japan points system changes.
CDJapan is in English. For HMV Japan and Amazon Japan, I usually browse and search for items in Japanese as it returns better search results. If you get stuck, just turn on the English language option to view the terms. Amazon Japan offers a points system too but I don’t buy from them as often.
This is a value-per-yen guide to the points systems of Amazon Japan, CDJapan and HMV Japan.
