In Japan, the Imperial chronologies include eight reigning empresses from ancient times up through the Edo period; however, their successors were most often selected from amongst the males of the paternal Imperial bloodline, which is why some conservative scholars argue that the women's reigns were temporary and that male-only succession tradition must be maintained."Life in the Cloudy Imperial Fishbowl," Japan Times. 27 March 2007.
