IC cards and Japan Rail Pass

Hi all,

I'm planning a trip to Japan next year and would like to go to the following places:

Tokyo (3 nights)
Tokyo - Shizuoka
Shizuoka (1 night)
Shizuoka - Kyoto
Kyoto (2 nights)
Kyoto to Hiroshima
Hiroshima (2 nights)
Hiroshima to Tokyo

So basically I'm going like Tokyo - Shizuoka - Kyoto - Hiroshima - Tokyo

It will be about 9 days and I'm planning to get the 7 days Japan Rail Pass and activate it on the second or third day of my trip since I'm zipping around many places.

The problem is I don't know which IC cards (Pasmo, Suica, Icoca) to get since I will be traveling within Shizuoka, Hiroshima, and Kyoto as well. I need an IC card for traveling in Tokyo for my first 3 days too. Should I consider getting individual tickets when traveling in each prefecture? Or is there a card which can be used everywhere?

I read the information online but was still confused as they mentioned it could now be used interchangeably.
Please advise. Thank you!
