Buying tickets at JR ticket station

Hello everyone,

My 1st trip to Kansai area with my best buddy in May. I would like to find out this.

I am wondering can I buy in advance for seat reservation for return tickets between Shin-Osaka and Kinosakionsen at any JR ticket stations in Japan? Eg. at the JR ticket counter in Centrair or at JR Nagoya Station? Must the tickets be bought only from Shin-Osaka Station?

Glad to have any info on this...thank you!

You can buy any JR tickets at any JR station: so YES, you may buy your tickets at the JR counter at Centrair or at JR Nagoya.

No JR sales ticket office/window at Centrair(NGO) bc no JR rail.

"Meitetsu" is different rail company against JR.

But maybe possible at Meitetsu travel plaza(Travel agency) near train ticket gate.

If NOT at JR Nagoya stn ticket office possible.
Reserved seat ticket sales starts just one month before.

thanks for the infor, AusTF and PND.

My intention is to avoid making a trip down to Shin-Osaka station just for the purchase of the reserved train ticket to Kinosakionsen as I am staying a distance away from Shin-Osaka station. I was also afraid of not able to get reserved seat if I buy the ticket on the morning of departure. So hoping to buy the tickets elsewhere from any JR ticket office if possible.

Ok will try my luck at those places mentioned. thanks!
