14 From Hiroshima Airport Please take the Geiyo Bus to Shiraichi Station and transfer to the train bound for Saijo, Hiroshima and Iwakuni and get off at Saijo. From Hiroshima Station Please take a train on the Sanyohonsen line bound for Saijo, Shiraichi and Okayama. The train usually departs from platform 5, but occasionally will depart from other platforms. It will take approximately 30 minutes by express and 40 minutes by ordinary train.
