Need advice on Iterinary

Hi,
I will be visiting Japan in Nov and would like advice on the following iterinary :-

Day 1 - Arrival in Osaka & visit Umeda/Namba area

Day 2 - Morning - travel to Himeji to visit Himeji Castle

Day 2 - Afternoon - Travel to Kobe from Himeji.
In Kobe, visit Sake Breweries of Nada and Arima Onsen

Day 3 - Day trip to Kyoto from Osaka

Day 4 - Day trip to Hiroshima from Osaka

Day 5 - Osaka to Tokyo

Day 6 - Tokyo

Day 7/8 - Tokyo (Disneyland/DisneySea)

Day 9 - Home sweet home


I like to know if the above iterinary looks OK...especially for Day 2, not sure if it is possible to visit Himeji & Kobe within a day and hence would like to have some feedback.

Thanks.

Day 2 is busy, but possible if you start the day early and stay overnight in Arima Onsen.
