Been or gone ?

[GabrielPaixão]

Hey, what's the difference between been and gone ?
Example: She's gone to Japan. / She's been to Japan.

Thanks.

[5jj]

She's gone to Japan. She is in Japan now.
She's been to Japan. She has visited Japan in the past, but she is not there now.

[BobK]

And to continue the example:

'Can I speak to Julie?'/' No, she's gone to Japan. She'll be back next month.'

But when she returns:

'Who can I speak to about dealing with Japan?' /'Try Julie, she's been there. She's only been back a few weeks.'
