How many days, and why fewer is worse here
Three days is the honest minimum, and it will feel tight. Kyoto's sights are not clustered the way a European old town is: they sit in a ring around the edges of the city, in different directions, and each one wants half a day rather than an hour.
Four or five days is where Kyoto stops feeling like a checklist. It also opens up Nara and Osaka as day trips, both close enough to do without moving hotels — which is the shape Joru's day-trip planning exists for.
