Fukuoka to Osaka JR Pass

Hi! I am planning to visit Japan this March, I am arriving in Fukuoka Japan but I also want to explore Osaka. My question is upon purchasing JR Pass for tourist, are there shinkansen available for JR tourist pass from FUKUOKA to OSAKA, and OSAKA to FUKUOKA. and if there are available, how many hours would it take. I hope someone could help me. Thanks.

This pas is 9000 yen cheaper than a regular nation wide jr pass if only travel between Fukuoka and Osaka. And back.

Yes, is the answer.
Either the whole country pass or the Sanyo-Sanin pass (https://www.westjr.co.jp/global/en/ticket/pass/)
