I love Japanese femme rockers. They whine, growl, scream, screech and sing through their albums so charmingly. The Japanese language has a distinctive way of treating gender in lyrics so it's interesting listening to them, even in broken English.
Some of my favorites are Shena Ringo (she's been compared to Bjork, Lauper and Stefani), Cocco, Seagull Screaming Kiss Her Kiss Her, Youjeen, Shonen Knife, Bugy Craxone and Lisa Go.
Just my two cents.
