A small excerpt:
"According to Irokawa, the females who draw the greatest pleasure from the sexual act hail from Hokkaido, Iwate and Gifu. ("All the women I asked in Hokkaido said they did it because they enjoyed it," he relates.) On the other hand, women who moan the loudest come from Chiba, followed by Fukuoka and Nagano. Chiba, likewise, boasts the highest percentage of vibrator ownership, again followed by Fukuoka and then Kumamoto. (Females in these three prefectures have a reputation for being virtuosos at teasing men.)"
