Buying tickets from touts?

Im currently in Tokyo and really want to see Polysics play, however their Akskusa gig for next week is sold out and I cant tell if theyve any more nearby comming up. So I was wondering if its normally possible to buy spare tickets on the day. Either from a gig goer or from a tout. Is this legal as I know in a few places, touting isnt. Also Its 3000yen ticket, so what may I be expected to pay?

Touting is illegal in Japan. But a lot of people buy from them. But then, the income goes to the yakuza, criminal organizations that usually make money buy selling drugs or murdering people. Also, the premium is quite out of the question. In my 30 years of attending gigs, I've never bought from touts.

A lot of people buy from gig goers at the venue on the day. But there's a lot less gig goer tickets than touts.

Another great option is using internet fan forums. A lot of them don't allow ticket trade, but at least you may be able to obtain information.

So I Have A Better Chance Of Standing Outside Early Before The Gig With A Sign Saying Im Looking For A Ticket?

You can get just about anything if you're willing to pay the price.
