We've made a Japanese subtitled version of the Google Lunar X PRIZE promotional video, Moon 2.0 - Join the Revolution.
See: Moon 2.0 in Japanese
Note, there is a small arrow on the bottom right corner of the YouTube viewer it enables/disables the subtitle captions (see How to Show YouTube Subtitles).
This is a brand new feature in YouTube.. let us know what you think about it.
