Song in Returning Japanese

[begens]

Does anyone know the Japanese song played in part 1 & part 2 of Returning Japanese ?

The song is first heard when the Hills are in the taxi in Japan going to the hotel after arriving at the airport. It's a catchy Japanese tune...very upbeat and pop.

I think it's by Seiko Matsuda (a famous Japanese Pop Star), who also has a cameo....but I'm not sure.

I've been trying to find this song for the 2 years with no luck.

Thanks in advance.
