Otoshi was the president of IBM Japan between 1999 and 2008. As Tokyo Reporter points out, he was, until recently, a senior adviser to IBM.
A fellow commuter noticed that Otoshi was doing something odd with his iPod and notified station staff. Numerous questionable files were discovered on his iPod. The former exec confessed to authorities, adding, "I have an interest in peeping photos."
In the wake of this incident, Otoshi has submitted his resignation as senior adviser to IBM.
