No JR direct train and no line JR Sanin main line from JR Osaka sta
need some transfers usual however,Highway bus[高速バス] operate
to Hamada stn and Masuda stn from Osaka no transfer but need booking.
JR trains and Highway bus operate every day but depend on yr dep date/time.
If bus booking full already you cannot. JR trains no worry.

梅田[Umeda] means JR Osaka stn area.
(non JR lines using "Umeda" a lot)

there is something i just someone to clearify for me.

most of the trains are jr line which means i can only use them if im buying the intenational or western jr lines in advanced outside of japan?

if im only using the train once and then 3 weeks will not use it and than will need it again is it possible to purchase a secondary ticket that will be activated only in 3 weeks after im in japan?

Thank you
this site is amazing.
