How to travel between Iwaki and Tokyo
By limited express train
Tokyo (Ueno Station) and Iwaki (Yumoto Station) are connected by hourly Super Hitachi limited express trains along the JR Joban Line (2 hours, around 6000 yen). The trip is fully covered by the Japan Rail Pass, JR East Tohoku Area Pass and JR East South Hokkaido Pass. Note that Yumoto Station is closer to most of the city's tourist attractions than Iwaki Station in the city center.
By local trains
By local trains, the one way trip from Tokyo's Ueno Station to Iwaki's Yumoto Station takes about four hours and involves one transfer of trains at Mito. The regular one way fare is 3670 yen, however, with a Seishun 18 Kippu you could theoretically do the trip for as little as 2300 yen.
By highway bus
Multiple bus companies operate highway buses every 30 minutes between Tokyo Station and Iwaki Station (3 hours, 3350 yen). Instead of using Iwaki Station, it can be more convenient to get off at the Iwaki Yumoto IC bus stop (160 minutes, 3200 yen), not far from the Spa Resort Hawaiians, from where infrequent local buses provide transportation to Yumoto Station and the spa resort.
Free bus to Spa Resort Hawaiians for staying guests
Spa Resort Hawaiians runs daily, free bus services for staying guests to and from Tokyo Station (3 hours), Shinjuku Station (3.5 hours), Yokohama Station (3.5 hours) and Saitama Shintoshin Station (3 hours). Advance reservations are required.

Most of the attractions in Iwaki are located near Yumoto Station and the Onahama (小名浜) port area, rather than in the city center around Iwaki Station. Some attractions are located within walking distance of Yumoto Station, while Spa Resort Hawaiians is accessible from the station by local buses or free shuttle bus. Local buses run between the Onahama area and both Yumoto and Izumi Stations.
An alternative would be to tour the city by rental car, which can be convenient considering that some of the attractions are accessible only by infrequent local buses. Car rental outlets can be found close to Iwaki and Izumi Stations.
