Guidance on collection of JR West reserved tickets

Good Day Daniel-san,

I am planning to travel from Tokyo (fly in from Narita Airport) to Nagano, then Nagano to Kyoto.

For the trip from Nagano to Kyoto, I intend to travel by train i.e. shinkasen with tickets reservations purchased in advance online via JR west website.

Understand from the link (https://www.jr-odekake.net/eki/global/en/howto/train-reservation/receive/station) that we could collect my train ticket from Tokyo/Shinjuku - JR East Travel Service Centers. - Could you confirm my understanding on this, pls?

Otherwise, based on my itinerary (Tokyo-Nagano-Kyoto), where would you advise me to collect my reservation tickets?

Appreciate your kind guidance. Thank you.

Regards
Steve
