A couple of weeks ago I went to see my friend Sachika sing at an outdoor event and later went to karaoke with her and her friend. Sachika is not a professional singer but she has done a lot of singing over the years since age 6. She likes to sing R&B, pop, enka, and her own original songs.
Some other videos of her singing:
Singing "If Ain't Got You" by Alicia Keyes
Singing the Theme Song to Mito Komon TV Show
Singing Enka Classic Tsugaru Kaikyo Fuyugeshiki (津軽海峡・冬景色)
Singing Norah Jones "Don't Know Why"
