7 day pass Seto, Kyoto, Tokyo, Kamakura

I'll be in Japan for 30 days in December. I'm flying into Tokyo and then going to Seto for three weeks (December 2-22). I'm buying a single ticket for this journey.

Will I save money if I buy a 7 day pass for my travels from December 22-29? I go to Narita Airport on December 30, but the 7 day pass will have expired. I used the Jrail Pass calculator and it looks like buying individual tickets is cheaper.

December 22 Ozone to Kyoto
December 22-25 Kyoto
December 26 Kichijoji
December 26 Yoyogi
December 28 Kamakura
December 29 Shibuya

Thanks, Grace
