There were many Samurai in old times in Japan, as you may know, but I have never visited any battle field where Samurai had fought. I donâ€™t think battle field tourism is popular in Japan.
However, there are several memorial places and museums which appeal the importance of peace after the world war second.
Most students visit Hiroshima or Nagasaki by school trip at least once and learn sincerely how citizens suffered from the war, especially from atomic bombs, and importance of peace. (Iâ€™d like to add that I also learnt Japan made Asian people suffer. ) The places never can be amusement park or casino. We seriously visit there and listened to the real voice(story) who experienced atomic bombs. I am quite sure most people swear in their mind that they will never participate in wars. Japanese also keep the constitution that Japan donâ€™t hold army again, and never make atomic bombs.
And now...isnâ€™t it irony that now Japan is suffering from nuclear plants problem, and the heros who are tackling with the plants are Japanese â€œself-defenseâ€ army.
