Hi we are 4 adults and 2 kids (8 and 5 years old) spending 2 weeks in japan. We are doing tokyo (7-11 dec), sapporo (11-15 dec) and Osaka 15-20 dec), and flying back via tokyo(21 dec). Would it be best to get a two week JR pass or alternatively just a 1 week pass ( activate it in Sapporo on the 14th), and buy a separate Hokkaido regional pass during our stay in Hokkaido. Does that work out more economical? Because we are planning on taking the bullet train back from Osaka to Tokyo on the 20th, so the 1 week pass will still be valid. Does the JR pass cover tokyo metro?
Hope this is not too confusing. Thank you
