Advice for places to visit in Iwaki

Need some advice during my visit. I will be visiting Japan in early December from 6th-16th, 8th -10th I will be renting a car and making my way to Iwaki area, my main visit will be Aquarium Fukushima and sounding areas for a seafood meal, and the next day will be to the Abukumado Cave, can anyone suggest any other places to visit in surrounding area, on the 11th I will make my way back to Tokyo, could be anytime from afternoon to late at night, so places to visit can also be on the route back to Tokyo from Iwaki.

I am not really interest in temples, but like the country side, zoo's and places to see animals.


Thanks
