For some reason I missed an official JAXA video posted before STS-131. The intro is really something. Not sure if the following unmodified screencaps give it justice, but here we have "ヤマト・ナデシコ 宇宙へ", a motion shot of closed eyes, and the blue rose (shown 3 times).
No idea what this messaging was intended to carry, but I guess it's something to chew on for the people who think that "Yamato Nadesico" equals to "stay in the kitchen and make tea". Not that they ever would.
The rest of the video is an ordinary interview.
