I have participated in a few of this woman's surveys. They were all to do with eating habits of foreign women in Japan.
The questions were basic survey questions about what I have eaten over the last few months and what I plan to eat in the next few months and multichoice questions to see if I could understand the kanji of the nutritional information on the back of food packaging.
Also, what food I would consider to be lowest fat.. choices like: ramen, combini bentos, tempura etc...
