TOKYO – A 25-year-old man has been served a fresh arrest warrant for allegedly creating a computer virus using generative artificial intelligence (AI), the Metropolitan Police Department (MPD)'s cybercrime control division announced on May 28, in what is believed to be the first such case in Japan.

Ryuki Hayashi, an unemployed resident of the Kanagawa Prefecture city of Kawasaki, was served the warrant on suspicion of making electronic or magnetic records containing unauthorized commands.

Hayashi is accused of creating a virus similar to ransomware, which destroys computer data and demands ransom in cryptocurrency, using his home computer and smartphone on March 31, 2023. He has reportedly admitted to the allegations, telling police, “I thought I could do anything by asking AI. I wanted to make easy money.”

    The conviction rate is 99.3%. By only stating this high conviction rate it is often misunderstood as too high—however, this high conviction rate drops significantly when accounting for the fact that Japanese prosecutors drop roughly half the cases they are given. If measured in the same way, the United States’ federal conviction rate would be 99.8%.[14][15][16]

      Comparing Japan to a prison colony makes it look a little more reasonable.

        I don’t agree with most western philosophies of prison, the US is probably the worst amongst them (but most of that comes at the state level), I was just highlighting that Japan isn’t in some way uniquely bad for ‘western’ law systems. Indeed, conviction rate is a really hard stat to do any sort of apples to apples comparison for because different countries count and report it different ways.
