I assume by "that year", you mean this year, since Byuu's (sigh, "alleged") suicide note was posted in June. But frankly, the notion that there was an entire year in which not a single foreign citizen died in Japan is absurd on it's face. Surely you can point me to that press release, and maybe some news coverage of that statistical miracle.

There's also a statement given to USA Today by their employer confirming their death, including their full name (previously not public), and a new photograph of them. I suppose that was part of the con, or hell, maybe USA Today is in on the conspiracy.
