JR Fukuhoku Yutaka Line's Kido Nanzoinmae Station is the nearest station. I think there is a guide board, so if you follow it, you will arrive in 10 minutes at the earliest.

I did not arrive by cruise ship. I flew in. You can get there 25 minutes by train from Hakata station. It should be easily doable if you have six hours. Once you arrive in the small the town the walk to the temple is short...about 5 minutes.

I think you can still go there earlier. You can still roam around the area, I think. Its never a problem, if waiting is not an issue to you.
