This morning, Nintendo put on a special Japan-only Nintendo Direct specifically for Pikmin 3. It's basically a "Let's Play" for the game starring Miyamoto, as he leads someone through a demonstration of a typical level.
For those of you who just want the footage, it technically starts at 2:50 in, but you don't really get anything past menu footage until approximately 4:50. The presentation may be entirely in Japanese, but Miyamoto's enthusiasm is a universal language.
