Japanese chart positions

I think a note of explanation is in order regarding the quoted Japanese chart positions and why they seem so low relative to how popular Queen were in Japan through the 1970s and early 1980s. There are no 'official' charts in Japan (the equivalent to Billboard/Music Week/BBC) and so there are a variety of different charts. One chart (as quoted here) is published by a Japanese music magazine and this chart tends to be dominated by domestic music as most Japanese people prefer to buy albums rather than singles. So, Queen singles do not do so well in terms of highest position, though the number of weeks on the chart gives you a good indication of the popularity of the song. There is also an FM-radio chart based on listeners requests and most Queen songs from Keep Yourself Alive to Staying Power did very well in this chart, most getting to number one.

Thanks to Tadao Ishimi for the Japanese chart information.
