Digging into Ancient China: The Development of Fortified Cities Kenji Sugimoto Price: 540 yen. Out of print in 1986. The condition is good for a book almost 40 years old, but please forgive some age-related deterioration and fading. Used copies are available on Amazon, etc., but this is cheaper including shipping. *I generally do not accept price negotiations as it is a hassle. Thank you for your understanding.
