Iwakiいわき
Give Iwaki one full day if you are already in Fukushima or Mito; two nights if you want Spa Resort Hawaiians plus the coast. Not worth a dedicated trip from Tokyo.
Iwaki is a coastal city of about 345,000 people in southern Fukushima, on the JR Joban Line between Mito and Sendai. It is one of Japan's sunniest and mildest cities, with a national-treasure temple, a good aquarium, a lighthouse on a cliff and a large hot-spring waterpark. Sights are spread over a wide area, so a car or careful bus planning matters more here than in most Japanese cities.

Getting around
The city is wide and low-density. JR Joban Line links Iwaki, Uchigo and Yumoto; local buses reach Onahama and the coast but run infrequently. A rental car is the fastest way to combine Shiramizu, the coast and the fossil sites in one day. Taxis are available at Iwaki Station.
