"Japanese Girls鈥� Names"
by Kumi Furuichi
It used to be very typical for Japanese girls鈥� names to end with 鈥渒o.鈥� (The trend might have started around my
grandmothers鈥� generation and its peak might have been around my mother鈥檚 generation.) 鈥淜o鈥� means 鈥渃hild鈥� in Chinese characters. Parents would name their daughters with 鈥渒o鈥� attaching to other Chinese characters which have meanings that they want their daughters to become, such as Sachiko鈥攈appy child, Yoshiko鈥攁 good child, Yasuko鈥攁 healthy child, and so on.

I have a feeling that, while 70 percent or more of my mother鈥檚 generation would have names with 鈥渒o鈥� at the end,
the proportion has dropped among my peers. I wrote down all my Japanese friends鈥�, ex-classmates鈥�, co-workers, and
acquaintances鈥� names that I could remember. Following are the names. (Some are repeats.) Test to see if the proportion has
dropped for this generation.

Over the past few decades, public health officials have examined the link between weight concerns and teen girls' smoking. Researchers surveyed a group of 273 randomly selected teen girls living in Massachusetts (between 12 and 15 years old). After four years the girls were surveyed again.
