Finding the bells of old Tokyo

American author Anna Sherman lived in Tokyo for seven years, and became fascinated with the nine bells that would ring out over the city during the Edo period, helping to keep time for the public. In her book, The Bells of Old Tokyo, she documents her travels through the city to find the bells and examines how the concept of time in Japanese culture changed. She also details her encounters with some of the city's colourful residents - including the owner of her beloved coffee shop.
