We will be travelling to Japan April 23 - May 2. Our travel is limited and I don't think the passes would be cost effective but just want to confirm that is correct. Here are the rail routes we will travel over 10 days:
Narita to Shibuya
Shibuya to Tachikaya
Tachikaya to Nagano
Nagano to Shinjuku
Shinjuku to Narita
Thank you for your assistance!
