Anyone who knows the history of Hiroshima will surely visit the Peace Memorial Museum when they come to Hiroshima. I arrived around 9 AM and already saw many buses of Japanese students, more than tourists, arriving in front of the museum. I didn't expect it to be so crowded on a Thursday morning, which somewhat affected the visiting experience. The entrance is on the right side of the museum. If you buy tickets in advance on Klook, you don't need to pick up physical tickets; you can just scan the QR code at the entrance. I highly recommend renting an audio guide as well; I think it makes the entire visit much more informative! After more than an hour of visiting, I felt the fragility of human life, but also the strength of the human will!
