Except that the "flowers" are sakura, which have symbolism to not only life and death, but used in scenery to represent a fallen samurai warrior. And are not really gender based, at least.
And pink, in the past, used to be the color used on boys, due to it being a lighter shade of red, while blue was for girls. But some countries still apply that old traditional method. Japan included, I would think? They don't hold pink in regard to the typical sex shade as much as we do in the West, from what I heard.
But you should have confirmation on that, since you're the Japanese translator and are more in tune with the culture.
