JR pass of Regional Pass?

Hi there,

I would like to have advice for which pass fits the best with our itinerary.

23 July Arrival Kansai airport and transfer to Kobe where we stay for 3 days
24 July Daytrip to Osaka
25 July Daytrip to Himeji
26 July Kobe - Hiroshima
27 July daytrip Hiroshima Miyajima
28 July Hiroshima - Kyoto.

Can you tell me which pass is the best for us? the JR pass of one of the Regional passes like Kansai Hiroshima Area Pass or Sanyo- San 'n Nother Kyush Pass ?

Kind regards,
Dieke
