By the time of Tokimuni's premature death in 1284, Rinzai Zen had been effectively established as the faith of the Kamakura rulers. His successor continued the development of Zen establishments, supported by new Chinese masters who also began teaching Chinese culture (calligraphy, literature, ink painting, philosophy) to the Kamakura warriors along with their Zen. Since the faith was definitely beginning to boom, the government prudently published a list of restrictions for Zen monasteries, including an abolition of arms (a traditional problem with the other sects) and a limit on the number of pretty boys (novices) that could be quartered in a compound to tempt the monks. The maximum number of monks in each monastery also was prescribed, and severe rules were established governing discipline. Out of this era in the late thirteenth century evolved an organization of Zen temples in Kyoto and Kamakura based on the Sung Chinese model of five main monasteries (called the "five mountains" or _gozan_) and a network of ten officially recognized subsidiary temples. Furthermore, Chinese culture became so fashionable in Kamakura that collections of Sung art began appearing among the illiterate provincial warriors--an early harbinger of the Japanese evolution of Zen from asceticism to aesthetics.6 The creation of the _gozan _system at the end of the thirteenth century gave Zen a formal role in the religious structure of Japan. Zen was now fashionable and had powerful friends, a perfect combination to foster growth and influence. On the sometimes pointed urging of the government, temples from other sects were converted to Zen establishments by local authorities throughout Japan.7 The court and aristocracy in Kyoto also began taking an interest in pure, Sung-style Rinzai. Temples were built in Kyoto (or converted from other sects), and even the cloistered emperors began to meditate (perhaps searching less for enlightenment than for the rumored occult powers). When the Kamakura regime collapsed in the mid-fourteenth century and warriors of the newly ascendent Ashikaga clan returned the seat of government to Kyoto, the old capital was already well acquainted with Zen's political importance. However, although Rinzai Zen had made much visible headway in Japan--the ruling classes increasingly meditated on koans, and Chinese monks operated new Sung-style monasteries--the depth of understanding seems disappointingly superficial overall. The _gozan _system soon turned so political, as monasteries competed for official favor, that before long establishment Zen was almost devoid of spiritual content. In many ways, Japanese Zen became decadent almost from the start. The immense prestige of imported Chinese art and ideas, together with the powerful role of the Zen clerics as virtually the only group sufficiently educated to oversee relations with the continent, meant that early on, Zen's cultural role became as telling as its spiritual place.
