Rockin'f

ロッキンF

Since July 1976. Probably a good magazine as it started with Jimmy Page cover. (...) This magazine has changed their direction and currently is only for Japanese rock music. So you do not need to bother yourself to get recent issues. (Yasuhiro Shiga)
Rockin'f (ロッキンf) is a magazine focused on rock, heavy metal, and (to a lesser extent) hardcore punk music. In the beginning of 2002 the publisher Shinyusha Co., Ltd. goes bankruptcy. In 2005, another publisher takes over the work. (wikipedia)
Last series of Rockin'f (2005-2007) contained 28 issues. Since October 2007 the magazine was retitled WeROCK and issue numbering restarted from 1.

I think that the rest of the text doesn't have any interesting info. It's just the unknown author's impression on FZ, like "It seems that this man is interesting probably because..." etc.
