I am planning to visit Japan from the January 15 to January 28. My itinerary is below. Could you tell me if it's better buying a JR pass or purchase tickets as I arrive at each train station?
January 15 - Arrive in Tokyo Narita Airport
January 18 - From Tokyo to Osaka
January 19 - From Osaka to Nara (day trip), then back to Osaka
January 21 - From Osaka to Kyoto
January 23 - From Kyoto to Tokyo
Looking forward to your advice. Thanks a lot!
