I posted this on Reddit but I figured other people would be interested here.
I’ve seen a few requests about Kyary before, and I always end up typing out a long list, so here it is for future reference!
Technically this type of music is called technopop, though i it has bled over into mainstream jpop now. Sometimes the term Jtek (Japanese Techno) is used, though that’s usually in reference to the first couple of artists on this list. Most of these songs are heavily influenced by electrohouse styles (i.e., Birdy Nam Nam, Daft Punk, Justice, etc).
There is also Picopop, which has more of an 8-bit feel, kind of like a cousin of chiptune. Examples: Sonic Coaster Pop , YMCK
And the genre that the current trend of Japanese technopop was influenced by, Shibuya-Kei. Examples: Copter 4016882 (yup, another Nakata project), old Capsule
Here’s a close cousin, Vocaloid music, which is music composed around samples from Vocaloid voice bank software. This type of music tends to have a lot more “noise”. Examples: AVTechNO! , anything TeddyLoid produces
