Yasakune Shrine is quite interesting. Not many vehicles, couple of tanks, aircraft, artillery, cannon. But it gives a potted history of Japan's military past. Day of infamy and Commodore Perry's Black Ships, Russo-Japanese War of 1905, WW1 and their Allies. Then the history gets a little fuzzy. Not a lot of mention of the Nanking, or details about WW2 except the brave Kamikaze. Yes the museum is heavily biased, but all Japanese history is.
Similarly, I went to the Museum in Ma'an, Jordan. This was a major base during the Turkish occupation and heavily garrisoned during WWI. Lawrence's forces only skirted the area as too many troops. But was there anything to do with T.E. Lawrence in the museum, not a bit.
I have issue about the Holocaust display at the Imperial War Museum London. The IWM is/was supposed to be a celebration and commemoration of Britain's military past. Yes, Brit soldiers liberated Concentration Camps, but the holocaust is not primarily part of Britain's history. The display is to get people in the door and its very emotive. Many artefacts had to bought in to put the display on, which also defeats the objective.
Anyway, my point was don't just go because it's biased, be proud of that fact. As an American, (I think the U.S. had something to do with us in WW2), go and be proud of who you are. Damn, just fallen off my soap-box.
