Staff writer Hiroki Totoki is a Sony Bank director and an accidental author.
When he launched a weekly e-mail magazine in late January describing the making of the Internet bank, he did not expect his column to gain more than 13,000 registered readers in four months, let alone be published as a book.
His amusing anecdotes -- one of which tells how he surprised an official at the then Financial Supervisory Agency by simply asking how to obtain a banking license -- eventually attracted about 10 publishing firms.
