Is this worth a 7day JR railpass?

Hi all,

I am planning a trip as follows. Just wondering if a 7 day JR pass is my best option? Or any alternative?

And any comments on whether this is best way to maximise a week in Japan?

It's been very confusing surfing the net for transport options. Though I envy the Japanese for the very siphisticated infrastructure.

Appreciate your advice. Thank you very much!!

Day 1- arrive @ Haneda, head to Shinjuku via Tky monorail and JR Yamanote Line (have a dinner in Shinjuku with friend!)
Day 2 - Shinjuku to Kawaguchiko Stn (Via JR Chuo line, stopping at JR Otsuki stn for Fuji-kyukou Line if buying JR, or will take Romance car otherwise)
Day 3 - Kawaguchiko Stn to Kyoto (via Fuji-kyukou Line and JR Tokaido Shinkansen to Kyoto)
Day 5 - Then to Tokyo
Day 7 - Leave via Haneda
