Wu City is not a peaceful coastal town. This is Japan's maritime center.

I visited Hiroshima twice, and this time I saw their Naval Memorial Hall. The most impressive part was this passage: "Those who do not seek progress will not win. The best way is to rise up and change after defeat. Japan does not value progress. It only focuses on self-righteous cleanliness and morality, and has long forgotten the deep meaning of progress. Apart from rising up after defeat, what other ways can save Japan? If it does not wake up now, there is no hope. We are willing to be the pioneers (to save Japan). To die for the rebirth of Japan (using the verb 散る, which means the withering of cherry blossoms), isn't that what we want?" This passage is from "The End of Battleship Yamato" and quotes a captain who died in combat aboard the Yamato. Although it is full of self-admiring militarism, from the Japanese point of view, just like the people with lofty ideals who stood up when we experienced a national crisis, isn't it also a sacrifice for their country? Justice is a difficult thing to define. No matter how it is defined, it cannot be at the cost of invading or sacrificing other countries!
