From Namba where Swissotel is, we took the Kintetsu Nara Line Rapid and got to JR Nara in 37min JPY810. The tourism office is just a 3 min walk in front of the station. Get your one day bus pass for JPY500. This will bring you to most of the sights like Todaiji Temple, Kasuga Taisha Shrine, Gengoji Temple and the Heijo-kyo Palace Site. Check out details here
Jetso Tip: While in Nara, do try the wild vegetables served in the restaurants around the temple. The mushrooms and veg are so sweet !
