note: we will stay near dotonbori, kuromon market, denden so we can just go there at every night

thank you!

Day 2 may or may not be possible. Find out closing times for the Umeda Sky and the places after it.
Rest of the days are at a easy or even slow pace. I recommend seeing more than just the bamboo grove in Arashiyama. Is there much you want to do in Osaka's bay area that reckons the better half of the day?

thank you JH. will consider seeing rest of arashiyama.
where can i put himeji castle?

To visit Himeji, you need to remove something from your itinerary, because there's no room left! If you just want to take pictures of the castle, it'd be about a 2 hour round trip from Osaka if you take the shinkansen to Himeji. If you want to see inside the castle, it'd be a 1/2 to full day trip.
