Can I go to Shikoku Island using my JP rail pass (7 days)

Hello !

I bought a JP Rail pass (7 days) for my second trip in Japan late November. Briefly, my itinerary is as follows:

Day 1 (Nov 24th): Train from Osaka to Shikoku Island:
Day 2 (Nov 25th): Shikoku Island
Day 3 (Nov 26th): Train from Shikoku Island Hiroshima
Day 4: (Nov 27th): Miyajima Island
Day 5: (Nov 28th): Train from Hiroshima to Kanazawa
Day 6: (Nov 29th): Shirakawa-go
Day 7: (Nov 30th): Train from Kanazawa to Nagano

Can I use my pass to travel from Osake to Shikoku Island and then, from Shikoku Island to Hiroshima?

Your suggestions are welcome to help me to optimize my JP rail pass.

I thank you very much for your advice and kind help.
