I am very glad you and I are both on this thread, lest readers get some posters misinformation about Japan as it is today.
I think Japan does leave off some serious questioning of it’s military-imperial past, particularly in its academic curriculum.
I also think that in most ways Japan today is not the Japan of its military-imperial era, and in it’s general relations with all its Asian neighbors is behaving as one of the most responsible and charitable nations.
Some of those who criticize Japan most have their own historical issues they too try as hard as they can to sweep under the rug. Some are even now not governed as democratically or with as peaceful intents as Japan. In some ways I’d like to say to many of them - let you who are without sin cast the first stone.
Some years ago, WSJ ran a piece on a Japanese military officer who took the train to his base each morning. He always wore civilian clothes coming and going.
