Japanese Cheesecake

I remember my friend Olive made a really delicious cheesecake. She said it was 'Japanese Cheesecake'. The texture was very different with the New York Cheesecake, Japanese cheesecake has a sponge cake texture, but softer, moister, and airy that it melts in your mouth. So when I ate it, it didn't taste as rich as New York Cheesecake.
