I am a Trusted Account holder and have been using MtGox for more than 3 years.

Quite some BTC coins stuck now for 6 days. USD stuck for more than 5 months. No response to multiple support tickets. A tweet to Mark Karpeles with my support ticket reference got no reply.

Can anyone recommend a lawyer, preferable Tokyo based, to formally notify MtGox and its directors and put them in breach ?
