If you didn't know, it is only like 14,000 yen/person on the Nozomi Shinkansen from Tokyo to Osaka and Kyoto is just before Osaka on the line. If you took the slower train, it'd be cheaper, thats for sure.

Tip: if you want to move between Osaka and Kyoto, forget the Nozomi or slower shinkansen and take the Hankyu Railway to get between Kyoto and Osaka - take the Limited Express and not the Express / Local which can be a nail biting experience especially if you want to move quickly between Kyoto and Osaka. Its only a 35 min or so journey between the two cities!

Adults are charged ~14000yen / way on Nozomi (if children are taken along, the fee is half for them).

so 2*14000 = 28000 yen/way * 2 = 56000 yen approximately (this for Tokyo to Osaka, its less if you take it to Kyoto and buy a 5000 yen Kansai free train pass good for 3 days) (5000*4 = 20000 yen for 3 days!)

Sanosuke!
