Hi everyone,
What are possible questions that might be asked for お正月 (Japanese New Years) as a detailed study?
Thank you 
1. What it is.
2. When it is.
3. Why do they celebrate it?
4. How do they celebrate it and how did they originate?
5. Things they don't do.
6. How long it lasts and comparison against other countries (e.g. China).
7. Compare modern celebrations with ancient Japanese celebrations. (Especially with technology evolving, changes may have happened.)
8. How areas differ in celebrations. (Not a great point, but still...)
9. How foreign countries contribute to
Ooshougatsu/ Different influences on
Ooshougatsu.
10. Impact
Ooshogatsu makes to the economy (e.g. does it affect tourism, because Japanese natives return to their country? Does it affect businesses because they're closed?)
That's 10 points just off the top of my head for you.

Good luck. (Sorry it's not in Japanese, but I can't do all the hard work for you!

)
