GetKeyDown, GetButtonDown don't work when IME is enabled.

As the title, Keyboard input does not work properly, when IME is enabled. In the case of disabled IME, It's okay.

I want to know

-Is there any way to detect keyboard input on enabled IME?

or

-How to toggle ime mode.

^^

It would really help when you use shortcuts to write it out at least once. Shortcuts can have multiple meanings...

Take a look at the Input Method Editor support page.
