Mouth not moving when I move mouth

Looking at your image, I see no sublayers for your mouth. The mouth requires multiple images (layers) to perform correctly. You need visuals for the facial reactions of smile and surprise as well as assorted "visemes" to respond appropriately to audio input. Without these additional shapes, your character will not speak or even smile.

Japanese is converted to English using translation software.

There are many possible causes.
Check the audio input level value under the camera window.
(1) First, is the voice being input?
2) Is the input volume low?
Try the default puppet as well.

If that is not the cause, it may be a tagging error.
Can you attach a screenshot showing the tagging in detail?
Thanks.
