Keika Yamaguchi: Hello. My name is Keika Yamaguchi. My first name is spelled K-E-I-K-A. People often pronounce it as Kika. The correct pronunciation is "CAKE," as in bake a cake, then "AH," as if you're tasting the cake. Keika means flower of celebration based on my Chinese character, and my last name means mountain entrance today, but originally, the full meaning was entrance to the mountain fort.
