How much time for Hirazumi?

I only have two days in the north, I am visiting friends in Sendai, (I'm intending to see Zuihoden, the Mediatheque, Jozenji - dori Av, Matsushima Bay etc, potentially the Museum if time permits) I was only looking at seeing Chusonji and Motsuji in Hirazumi would a couple of hours be enough?

For the average traveler, I recommend a minimum of one hour for Chusonji. Two hours for the more interested. And one hour for Motsuji. Plus another hour for luggage management, orientation, toilet visits, transportation in between, etc. So, in total, I recommend 3-4 hours without meals. Slow travelers should allocate more time.
