A young Japanese woman in colorful African clothes appeared on the stage at a small club in Tokyo's central Roppongi district on April 25. She sat down on a low chair in front of an eight-stringed wooden instrument.

"Good evening, everyone. I am Anyango!" she announced. "Anyango" means "girl born in the morning" in Dholuo, the language of the Luo tribe who live beside Lake Victoria in Kenya. Anyango is also the stage name of Eriko Mukoyama, a musician who plays the nyatiti, a traditional Luo instrument.

Before the audience could finish applauding, Mukoyama started to pluck the strings at a quick tempo while creating a rhythm with the iron bells attached to her right ankle and an iron ring on her right toe.
