Staying in Japan for at least 2 1/2 weeks

Hi,

I'll be staying in Japan for 2 1/2 weeks. I am looking into getting a JR Pass for the following cities: Fukuoka-Hiroshima-Osaka-Kyoto-Tokyo.

There is going to be about 5 people in my party. Is there group passes or I would have to pay separately which would cost about $2,000 (USD) according to the check out page.

Thank you for taking the time!
