More about the book

"Twenty-year-old Taguchi Hiro has spent the last two years of his life living as a hikikomori--a shut-in who never leaves his room and has no human interaction--in his parents' home in Tokyo. As Hiro tentatively decides to reenter the world, he spends his days observing life around him from a park bench. Gradually he makes friends with Ohara Tetsu, a middle-aged salaryman who has lost his job but can't bring himself to tell his wife, and shows up every day in a suit and tie to pass the time on a nearby bench. As Hiro and Tetsu cautiously open up to each other, they discover in their sadness a common bond. Regrets and disappointments, as well as hopes and dreams, come to the surface until both find the strength to somehow give a new start to their lives."--From publisher's web site.
