Elizabeth Vining recounts her years as the tutor of the Crown Prince of Japan after World War II. It's unremarkable that she was chosen -- she seems eminently suitable in all respects, graced with a gentle dignity, respect for other cultures, and warmth for all people. She's clearly intelligent, and some of the parts I found quite interesting were about her methods of pedagogy and how she adapts her lessons to her pupils (who eventually include other schoolchildren and the Empress herself); that said, although she displays an awareness of global events and of war, there's a deliberate turn away from them. Vining concerns herself with people, not with politics.
Her role extended beyond mere grammar; she introduced the prince to unprecedented outings with Western boys, and was a fierce champion of his right to happiness and a child's carefree life despite his regimented schedule and residence (away from the rest of his family). I also appreciated her insistence that her students learn to think for themselves. And she won enormous affection from the royal family, which I think really holds the heart of this book, a tale of unlikely people learning about each other and coming to care for them. The royal family is...humanized to some extent, sometimes seeming a bit too good to be true, but I don't doubt Vining's experiences with them.
Post-war Japan makes up a tale to be told in itself, and Vining doesn't neglect this part of her stay. Again, it's not the most encompassing view, but it's written engagingly, with undisputed sincerity.
I think if you find the premise of this book fascinating at all, and you know of Vining's background going in (a librarian, a Quaker), you will not be disappointed. A quiet but fulfilling read.
