By train, you take the Tohoku Shinkansen to Ichinoseki station and then get on the local JR Tohoku Honsen bound for Morioka station and get off at Hiraizumi. Then take a taxi to Chusonji. It takes about 1.5 hours. If you want to walk, it's about a 25min. walk to the temple.
My boyfriend and I will be going to Sendai next week from Tokyo. We want to visit Hiraizumi and Chusonji. Could someone tell us how we get there?
