14 days JR Pass?

Hi,

Would you suggest buying 14 days JR pass or just pay as-is with the following itinerary?

Oct 11 - Narita airport > Fukuoka by airplane (already bought ticket)
Oct 12-15 - stay in Fukuoka area, friend's wedding, and may be 1 day to Huis ten boush.
Oct 15 mid-day - arrive at kobe by shinkansen, then transfer to Arima onsen
Oct 16 > 19 - stay at Namba area and may be 1 day to Kyoto
Oct 19 evening > 25 - arrive at Shinjuku by shinkansen, visit areas around Yamanote line, and may be 1 day to Gotemba Outlet (TBC).
Oct 25th mid-day - depart from Narita airport.

I don't think I will use much of JR line within Kansai area; As for Tokyo, our hotel is closer to the metro station than Shinjuku JR. So that holds me back from buying the pass...

Much appreciated for your help!!
