Omodaka's 21st-century disco version of Kokiriko Bushi -- an ancient folk song that Gokayama (Toyama prefecture) villagers used to perform for the local Shinto deities -- combines synthesized vocals with a Stevie Wonder-ish bassline and '80s video game chiptune sounds, and the wonderfully quirky and surreal video (animated by Teppei Maki) features a fragile skeleton dancer that shares the floor with lots of disembodied hands and floating eyeball-headed ladies.

Incidentally, the kokiriko is a type of percussion instrument made from old bamboo used in the roofs of traditional farmhouses. After being all but forgotten, Kokiriko Bushi was revived in the mid-20th century and has become one of Japan's most well-known folk songs.

Teppei Maki also directed the animation for DJ Kentaro's Tasogare Highway High...

...and he has worked on videos for Kaskade (Be Still), the Beat Crusaders (Your Song Is Good) and Fuuri (Nana Song), none of which appear to be available online.
