Osaka-tokyo-osaka

We will be travelling on June 12-19, this year. Only to use the JR pass from June 12-18. Moreover, we will be arriving at kansai airport around 19:10, and approximately 21:00 to exit the airport(thinking of immigration and waiting time for our luggages). Planning to buy the 7-day JR pass for our trip, at the airport as well because i heard you offer discounts if we buy it at your ticketing office. Are the JR bullet train inclusive in that price of $265.00 ( 7-day pass)?
We would like to explore Osaka-tokyo-osaka-kyoto-osaka😁
