It seems she's already gotten a lot of attention on blogs all over, but I didn't hear about her till last week, when I was wasting time reading journals at last.fm.
Japanese Tigarah mixes Brazilian baile funk music with hip hop in a way that makes me wanna hit a dance floor - Even though I could never dance to this kind of music... Her rhymes are supposedly clever, so if you (unlike me) are knowledgeable in Japanese, checking the lyrics out could perhaps be interesting. So far she has released one EP and an album should come out this fall.
Go visit her homepage to listen to all of the songs from her EP and download all remixes made by MR.D. You could also take a look at her MySpace for a few downloadable tracks from her EP, including my favorite below ^^
