A new best seller has appeared, bringing an old-fashioned love story into the digital age. "Densha Otoko (Trainman)," whose author writes under the pseudonym Nakano Hitori, is the saga of the romance of a 22-year-old otaku, the "Trainman," with "Miss Hermes," an attractive young woman he saves from the unwelcome attentions of a drunk on a train on his way home from Akihabara (Tokyo's otaku Mecca).

This story first came to public attention as postings from March through May this year on a message board on the Web site 2 Channel (Nichanneru) in which Trainman asked for and received advice from fellow geeks on how to approach Miss Hermes. These postings from Trainman reporting on the progress of his new relationship, and of encouragement from hundreds of anonymous well-wishers, were published in book-form by Shinchosha last month, selling over 260,000 copies in three weeks.

The tale of Trainman's transformation from a hapless geek to a self-confident young man in a relationship with an actual real-life young woman is indeed heartwarming. In his first posting he tells of his chance encounter in the train; two days later he receives a set of Hermes teacups from her as a thank-you gift and obsesses online on whether or not to telephone her and ask for a date. Finally he plucks up the courage to call her and they agree to meet for dinner -- his first ever date with a woman.
