OSAKA - HIROSHIMA - MIAJIMA - KYOTO - TOKYO

Hi,
Which pass would be best to visit the desired cities? My flight will arrive in OSAKA on 07/19 at 18:20 at the ITM airport and will depart from tokyo on 07/07 by NRT.
I saw that I will have to do the exchange at Shio Osaka station, but I did not see the possibility of picking up the pocket Wifi in the same place. I would also like to confirm what time the office works at Shio Osaka Station and how can I get the pocket Wifi.
My intentions go straight to Hiroshima:
Day 19 Osaka to Hiroshima
Day 20 Hyroshima and Miajima, going to Osaka at the end of the day
Day 21 Osaka, going to Kyoto at the end of the day
Day 22 Kyoto
Day 23 Kyoto going to Tokyo at the end of the day
Days 24 to 26 July Tokyo
