At the risk of telling you something you may already know, the most internationally recognized modern taiko group has got to be Kodo from Sado Island. If you like drums and lots of them you might want to check them out. Another interesting option is Shoukichi Kina, an Okinawan artist from the 70s/80s who mixes traditional Okinawan music (and instruments like the Jamisen) with a bit of rock. Beware the Enka and J-Pop...
