Questions about Tokyo city day trip

I am going to Tokyo and will stay there for 2 or 3 days. Here is my plan. Could someone let me know if it is possible to do it in 2 days in stead of 3? I don't have to go all the places if I don't have time. Which one do you think I can skip? Thanks for your help.

Day 1: Tsukijishijo築地市場,  Ginza銀座,  Imperial Palace皇居

Day 2: Asakusa浅草, Ueno上野

Day3: Shinjuku新宿, Harajuku原宿, Meiji-jingu明治神宮, Shibuya渋谷
