Itinerary check during GW

Edited due to golden week. How's it look as far as cities? Is luggage shipping/storage reliable during GW?

Edit 2 for "No detailed itinerary posts"

28: Arrive 1pm Tokyo – hotel, ship luggage to osaka. See tokyo list.

29: Osaka – first shinkansen out

30: Kyoto (overnight in ryoken)

1: Himeji/Kobe (Or more kyoto things)

2:  Base osaka/open day (Hiroshima, hijime/Kobe make up if kyoto yesterday)

3:  Tokyo (first or early shinkansen out) store luggage at hotel or train station

4: Leave 6pm Airport 230pm (Flight 6:25)

Doesn't seem like too much right?
