Ok, I'm planning a trip to Tokyo, Australia, and California to do in a few years time.. (Yes, I understand that I'm 17, with childhood dreams, but this trip IS going ahead ) 
  
And I was just wondering, what parks in the Tokyo/Japan area would be worth doing in a week.  
  
Also, Wondering which parks in Cali to do in a week. Also, If there is a good public transport service, or is it better just to hire a car. 
  
Cheers.
