I'd put money the Japanese gov/intel just sets up a virtual TOR in their own cloud and redirect all queries to the non-authenticating whistle blower site to their own completely controlled TOR service/network. It likely will just serve to be a honeypot.

edit: Also, for them to actually create an authenticating service, they'd have to establish their TOR service proxy to route through non-controlled Japanese friendly nations. By proxy, the Japanese are also given the authority of the US, and there are not many places he/she can route it to, or establish a network strong enough to deter Japanese gov./intel from tracking down dissenters.
