Looking for input on the basic Itinerary below to see if this is feasible or if there's any route I should be taking that are more efficient. I have not really figured out exactly what each day is going to consist of but mainly I am wondering about the cities that I will be staying/travelling to. Hoping that it will balance out well.

Nothing has been booked and dates are not specifically set but we are looking at Mid-Late February – Mid March.

Who: Girlfriend and I, late 20s, my third time, her second time.

Location: We love Tokyo and are hoping to at least stay a few days in Tokyo for this trip. We've gone to Kyoto Osaka and Nara. This time we definitely want to go to Hiroshima and Himeji.
