For all to note:
I am not a travel expert all this information stated above are by my own experience and research that i have done on my own. The pass might work well for me but it might not be suitable for you.
Please compare and draft out where you are going before you purchase for any pass as different passes have their own advantages and disadvantages.
As compared to Kansai area, i am not so familiar with Kanto area except for Tokyo.
I will share more on airport transfer, as this is quite important for all the visitors i guess.
