It is better for u to plan the route for the places u are going, then from google map can get the transport fees, from there on u can calculate if it is worth it. I didn't get the Kansai Thru Pass because it is not worth it for my travel route, instead i rely on Icoca 

My advice is plan and check the route from google map first, i don't think u can visit 5 places a day ( very rush ), i mostly travel to max of 3 places per day, the transportation cost at Japan is really expensive, better plan properly to save some money ( well if u are cash rich is ok jus buy KTP and save the hassle  )
