3 days (Jr Tokyo wide pass) + 7 days or 14 days JR pass

Hi, I’ll be flying to Tokyo in Dec for 14 days. My itinerary will be:

Osaka: 3nights
Kyoto: 3 nights
Mt Fuji/Lake Kawaguchiko: 1 night
Tokyo: 6 nights (1 day trip to Gala yuzawa snow resort)

I’m not sure which one will be better:
1) 3 days Tokyo Wide Pass + 7 days JR pass
2) 14 days JR pass

Thanks!
