Hi Jeff!

Here's a sample itinerary from Tokyo to Hiroshima by shinkansen. Just include your correct travel dates to get it:

this is the Hyperdia website. Since you cannot use the Nozomi Shinkansen with the JR pass, the link above unchecks the Nozomi and Private Rail boxes. You’ll get results valid with your JR pass.

Every time you look for shinkansen trips with a JR pass you can use the trick above to get the results approppriate to use with your JR Pass.

Here's some useful information from the Japan Rail Pass website:
