SuiteSisterMary's Journal: Which Wii game is this?

A while back, quite a while as I recall, I saw a commercial online for a Wii game, and I cannot remember what the title was. I'm hoping somebody here can help me.

The commercial involved a woman playing Wii; I seem to recall she was in a tank top or sports bra or something similar, exercise style gear, with a pony tail.

The game itself seemed to involve a traditional Japanese woman doing some exploring. Specific things I remember are the character using a torch (mapped to the Wiimote movements), brushing aside cobwebs, possibly waving away a flock of bats, and slitting a throat from behind.
