Using JR Rail pass for Shinkansen? Round trip.

I’ll be going to Tokyo to Kyoto just for a day trip there (round trip).

Could I use the JR Rail Pass for it? My AirBnB host told me to check if they allow it ( round trip for Shinkansen). I’ll be staying in Japan for 5 nights and considering buying the 7-Day pass.

It’s not worth it if that’s your only Shinkansen trip. Buy the special discount ticket instead, see this article for full details:
