I'm not much into music theory but on the keyboard if you play all of the black notes on the keyboard, you'll definitely get a "happy asian-sounding" sound, as funny as that may sound lol.

Hope that helps:

F#> G#> A# > C# > D# (then repeat up the scale as much as you can)

Or you can even play it backwards to go down the scale.

Kind of like that :)
