Kyoto on weekends vs. weekdays

Is it a big different of crowd in major kyoto tourist spot (kinkakuji,arashiyama,nijojo) between friday and saturday?

Kinkakuji will probably be always crowded regardless days, I was there on 2nd time before the place opened, and there was already crowd waiting.

Arashiyama probably will have more crowds on the weekend due to more domestic tourists visiting.

Nijojo, I don't recall any crowds there, at least not the amount of people you will classify as crowd..

is the kiyomizu temple packed if we go there at 8 or 9 am in the morning (weekday and weekend)?
and todaiji temple nara crowded in saturday afternoon ?

Kiyomizudera is almost always busy regardless of the day of the week, but it is generally less crowded in the mornings. Todaiji is probably a little busier on the weekends, but again, the earlier you go the less crowded it tends to be.

Todai-ji has crowds, but it is big, so it makes less of a difference. I found arashiyama quite spread out, so didn't notice the people there as much.

I always find that Arashiyama only gets busy around the bamboo grove area. If you go further up the mountain to look at temples other than Tenryuji, then it's not really busy at all.
