Hiroshima is also suffering from over tourism. The wait time just to buy a ticket to enter the museum at the Peace Park is now about an hour on busy days. The City just announced that they will try and implement an online option for buying tickets as well as increase the operating hours. Miyajima as well is really crowded. A friend went last week, hiked to the top, but was faced with an hour wait for the cable car to come back down.
