Agree. We are lucky to have Japanese friends in Kyoto who kindly took the time to show us around all the places we wanted to see and others we had not heard of.
Kyoto is amazing. I would recommend a few days as there is so much to see.
Also agree with the advice to get pocket Wi-Fi from the airport. We have done it there and I am currently in Taiwan and picked up Wi-Fi for around £30 for 3 weeks and can connect up to 4 devices to it.
