Help from rail pass experts

Hi. Even though we have been multiple times I haven't bothered with rail passes after the first time because we tend to treat ourselves to the Nozomi (yes, I know the carriages are the same, just humour me) etc.

So for our next trip (details below) I wasn't going to bother with passes but if there are area passes that might be useful, let me know. Work on the basis that once we are in a place we don't tend to move about much, usually taxis or walking :
17/4 NEX to Tokyo station;
18/4 Tokyo station to Bessho Onsen (Asama then the local train);
20/4 local train to Nagano, Asama to Karuizawa;
22/4 Karuizawa to Kyoto. I was going to take the Asama to Tokyo then Nozomi or Hikari to Kyoto;
25/4 Kyoto to Kinosaki Onsen (there is a JR train direct);
27/4 Back to Kyoto;
28/4 Kyoto to Enoshima. I think I have that one as shinkansen to Shinagawa then local trains;
30/4 Enoshima to Narita by NEX.

Any suggestions for passes? Thanks...

I am not a train pass expert since I am a Japanese so that I cannot use the train passes for foreigner, but I will try.
