Higashiyama Onsen is a quiet spa in a scenic valley just outside Aizu-Wakamatsu City in Fukushima Prefecture.
Travel time from Tokyo is about 90 minutes by the shinkansen north to Koriyama, and then about 60 minutes by an express train on the Banetsusai Line to Aizu-Wakamatsu. Frequent buses make the brief run from Aizu-Wakamatsu station to the spa, or you can take a taxi.
