Trip help

Hello, I´m planning a 13 days trip through japan next may 2019,

Since I´m arriving to NRT by 06:00 am, I´m thinking to go directly to hisroshima and then going back to tokyo as follows:

Day 1 direct trip NRT-Hiroshima I think we get there by noon, spending all the day and sleeping over.
Day 2 Spending part of the day in hiroshima and visit miyajima island, in the night (by 19:30 or 20:00) departure to Kobe, sleeping over in kobe.
Day 3 all the day in Kobe, in the night departure to osaka and sleeping over in osaka
Day 4 all day and sleeping over in osaka
Day 5 all day in osaka, by the night going to Nara and sleeping over in Nara
Day 6 all day in Nara, in the night going to kyoto and sleeping over
Day 7 all day and sleeping over in kyoto
Day 8 all day in kyoto, in the night going to tokyo and sleeping over
Day 9, 10, 11, and 12 to spend in tokyo and sourondings
Day 13 flight back

I wonder if this sounds good, I was thinking to buy 7 day JR pass and then use individual tickets in tokyo

Thanks
