Phoning Japan

I came back from Japan on April 22 and now find myself with a strong need to speak to one of my new-found friends.

I'll be calling from a BT landline in the UK to either a Fukuoka land line or a Vodafone handy phone (code 090). To be honest I'll probably end up forgetting to worry about the cost and call anyway, but if anyone can give me an idea of how much I'm likely to pay per minute I'd be grateful. We don't know when to shut up, you see...

Cheers for any and all help.
