The Fujiwara rulers failed to maintain adequate police forces, which left robbers free to prey on travelers. This is implicitly illustrated in novels by the terror that night travel inspired in the main characters. The shōen system enabled the accumulation of wealth by an aristocratic elite; the economic surplus can be linked to the cultural developments of the Heian period and the "pursuit of arts". The major Buddhist temples in Heian-kyō and Nara also made use of the shōen. The establishment of branches rurally and integration of some Shinto shrines within these temple networks reflects a greater "organizational dynamism".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Buddhist temples in which two cities made use of the shoen system?
Heian-kyō and Nara
