This is nothing earthshaking, just some really pretty HD video of the moon, as taken by India's current Chandrayaan mission. Very soothing to watch - if you're having a stressful day just stop, take 2 minutes off, and see the craters slide by like ocean waves. If you wanna skip to the end you'll see the really cool bit, as the orbiter approaches the terminator (the line where day meets night) and the moon's surface disappears in a honeycomb of shadows.
I don't know why the opening text is Japanese. You'd need the ask Ms. Riofrio, the Babe in the Universe, from whom I stole this. Personally, I find it adds a real Gamera vibe to the whole video, as if our little turtle friend in doing a lunar fly-by to pass the time.
