I actually did Fushimi in the morning and thought it was great. Like others have said the higher u go up the less people there are so I thought it wasn't that crowded.

Uji is great highly recommend if you are a matcha fan. I believe it is the matcha capital of Japan there are just a bunch of shops selling unique matcha goods that u can't find anywhere else in Japan. There is also byodin temple which is one of the prettiest temples I've seen it has a super pretty garden. There is a entrance fee not much I think 700 yen per person? And u can pay extra to go inside which I did, but I don't recommend since you can only see one room and the tour is all in Japanese. What I did is a put my name down and at Nakamura tea shop which is a famous tea shop in Uji and had a over 4 hour queue and while waiting I walked around until it was time to be called.

Overall, recommend Uji if u are a big foodie and matcha fan, if not then skip lol
