The soundtrack is "あなたの心に", performed by Megumi Hayashibara. It really is a nice track, I have it on iPod already. The lyrics are very simple, I can do karaoke with them after 3rd or 4th try. The song is about love, pretty much.
The pictures are quite compelling. They start as nostalgia inducing set, but then take upon a decisively progressive course (and I do not mean "progressive" as poisoned by modern American academia). The two final frames are pictures of American spacecraft and rockets. Probably, they didn't have good enough pictures of H-IIA in stock.
