Sorry to be that guy but Doomcloud is actually from Connecticut - same guy as Radlib/Oxygenstar/Steady C/SadNES/Warez Waldo.

Japan has a very active scene and there's a lot of shows happening all the time, especially in Tokyo and Kyoto. Besides the Japanese chipartists already mentioned, here's some more that I like:

Robotprins (Swedish but lives in Japan)
Kunio
TQ-Jam
maak
hizmi
tappy

I don't know much about other countries in asia, but I heard like a year or two ago Indonesia has some sort of Gameboy scene as well.

Yeah I was wondering about that too.

Isn't A.M.U. from Asia too?

Artists from Asia I know are:
Doomcloud, chibi-tech, NNNNNNNNNN, Toriena, Omodaka, YMCK, Kplekraft, USK, Cheapshot (Japan)
Sulumi (China)

well that's it

YMCK also happen to have created a super sweet 8-Bit VST known as the magical8bitplug.
Other than that, and the Square Sound Festival in Tokyo, I know pretty much nothing about the asian Chiptune scene

Hope I could help

Taiwan's chiptune scene is largely non-existent in what I feel is due to a huge emphasis on school and education.

Music equipment such as mixers, synthesizers and turntables are marked up due to them not having a market for it here.

Any "retro" consoles are shipped here from Japan. Very few retro gamers and due to lack of space, when a new console generation comes out, most people sell or get rid of the previous console.

Japan has some of the best artists in the scene (chibitech, NNNNNNNNNNNNN, Toriena, USK/BSK, Kplekraft), and plenty of gigs. Korea has me, and I suck. There might be some Koreans, but they remain hidden. Some other countries in Asia have small scenes that seem to be intertwined with either the EDM or rock/metal scenes. Good luck finding any Asian city more active than Tokyo.

Square Sounds Tokyo! Biggest chip event in Japan.

Big unknown to me is chipmusic / 8bit music scene in Asia.
Are there any active artists? Can you recommend me some websites, facebook, soundcloud etc etc???
Are there any events, festivals there?
