I need to know about japan?

Question:

I'm writing a story in which 95% takes place in Japan. I need to know the basic life of a Japanese 13-14 year old female with rich parents. ( Don't need the entire life just basically how it is.)
Info needed:
- School and how it works (vacation times, length, sports, arts, seating, etc.)
- Lifestyle
- Food names and what it is
- How female soccer leagues work in Japan (ages, tournaments,etc.)
- How rich families, with companies work.
- Honorifics, (-san, -sama, -kun, -chan, and how they are used)
- Anything else that may be help full
The character, is adopted into a rich Japanese family, joins a soccer league, goes to school, starts a sort of romance- love triangle- kind of thing.

Answer:

Girls from rich families (ojosama) usually goes to private girls-only schools (Christian/secular). Christian school is highly estimated by many rich families. In fiction stories about ojosama, schools' names like these are typical: Saint Margaret Jogakuin (女学院、Institute for girls) or Jogakuen/Joshigakuin (女学園/女子学院), Meikai-Gijuku Girls’ High etc.
This kind of School like Jogakuin or Jogakuen often contains elementary, junior high, high, or sometimes college or nursery school.
Students wear school uniform.
