To get to Kousanji on Ikuchijima Island, where the Hill of Future Hearts is located, there are three methods: car, boat, and bus, but going by car is the best option! If coming from the direction of Onomichi, enter the Shimanami Kaido from the Nishi-Seto Onomichi IC and get off at the Ikuchijima Kita IC after about 15 minutes. From there, it takes about 10 minutes to get to Kousanji, and since it's a seaside road, you can enjoy a scenic drive on the beautiful island! Note that there is also a Ikuchijima Minami IC, but it's only possible to get off for cars coming from the direction of Imabari, and cars coming from Onomichi cannot get off, so be careful! Since the number of boats and buses per day is low and it takes more than an hour one way, those who want to have a trip with high freedom without time constraints are recommended to go by car!
