I was certainly among the many travellers who apprehend visiting the city of Hiroshima but who are overcome by their natural curiosity to visit a place that is so significant in the history of humanity. Looking back, I really have no regrets about my visit and would encourage any future traveller to Japan to set aside a day to visit the city.
The main interest of Hiroshima is the visit of the great Peace Memorial Museum, which is particularly well-organised and incredibly moving, with numerous testimonials, photos and reconstructions that really help you understand what the population underwent after the explosion of the A-bomb.
Outside, I shall always remember the building called the dome, the last visual testimony of the effects of the bomb.
After this trying day, I highly recommend you offer yourself a pleasant culinary treat with the local speciality, "okonomiyaki", a sort of pancake prepared in front of you on a hotplate.
