Ok, i think food is a good one to compare as stated above liao
How about traditions...the role of woman in Sg and japan society?
Can oso compare the education system
The open-mindedness in sex between the 2 countries
Well...I studied about japan for a little while.
I think comparing role of women in singaporean and japan society, education, role of government, and military.
Now, I know next to nothing about Singaporean military and government, but as you probably know, Japan spends little resources on military because all they have is a small defense, since they do not want their people to die as what happened in WWII.
Remember to think about Japanese and Singaporean family life. Japanese men will put their job far ahead of their family, and they may be gone often on business trips etc. While the mother (who might not even love her husband, and vice versa) will spend a lot of time in her son/daughter's life, whether participating in school events or helping with work. Also, the grandparents may also take part in raising the children. (I know that doesn't often happen in America..so not sure if Singaporeans also have their extended family living in same house?)
Now..education is a big part of kids lives. They work hard and are often not allowed to have a part time job because their school does not permit it.
Japan has also been americanilized to some extent, and have taken many things from other cultures. And with singapore, I mean...you speak english, so you obviously have something going on there.
Good luck...
