We will be traveling from Kyoto to Hiroshima, spending the night on Miyajima Island then heading to Tokyo. There are 4 of us and I am planning on using the luggage service and having our bags sent straight from Kyoto to Tokyo. Pretty sure the 4 of us can get down to two overnight bags for Miyajima, but still don't want to carry those around with us while exploring Hiroshima. Are there lockers at the JR station we could store them in? Or near the ferry to Miyajima Island?
