As a shogun, Yoshimasa was even more distracted by Zen than his famous grandfather. He concentrated on encouraging the school of Sung-style ink painting, the Zen ritual of ceremonial tea, the art of flower arranging, and new styles of Zen-influenced architecture. Unfortunately, his apparently hereditary absence of interest in affairs of state ultimately brought about the disintegration of the Japanese political fabric. As the office of shogun weakened to the point of symbolism, Yoshimasa's power to tax became so frail that he was finally forced to borrow from the Zen monasteries. The real power in the land passed to the local feudal lords, or _daimyo_, men who governed entire domains, raised their own armies, and exercised far greater power than the _samurai_ of earlier times. What remained of Yoshimasa's power came to be exercised by his mistresses and his scheming wife, Tomi-ko. By his late twenties he was ready to retire entirely, the better to pursue Zen and its arts, but none of the women in the palace had yet presented him with a son who could become titular shogun. By 1464 Yoshimasa's patience was exhausted and he turned to one of his brothers who was in monastic orders and persuaded him to begin an apprenticeship for the shogunate. The brother wisely hesitated, pointing out that Tomi-ko, who was still in her twenties, might yet produce a son; but Yoshimasa won him over with solemn assurances that all sons who arrived would be made priests. Less than a year later Tomi-ko did indeed bear a son, setting the stage for the struggle that would eventually destroy Kyoto and signal the decline of the Ashikaga age of Zen culture. As it happened, there was already an animosity between Yoshimasa's principal adviser, Hosokawa Katsumoto, and Hosokawa's father-in-law, Yamana Sozen. When the child was born, Hosokawa, a member of the historic family of Ashikaga regents, favored retaining Yoshimasa's brother as shogun, so the ambitious Tomi-ko turned to Yamana to enlist his aid in reverting the office of shogun back to Yoshimasa and thence to her son. With a natural excuse for conflict finally at hand, the two old enemies Yamana and Hosokawa gathered their armies--both numbering near eighty thousand-- outside Kyoto. The impending tragedy was obvious to all, and Yoshimasa tried vainly to discourage the combatants. By that time, however, his voice counted for nothing, and in 1467 the inevitable conflict, now known as the Onin War, began. The war raged for a decade, until virtually all the majestic temples of Kyoto were burned and pillaged. Ironically, one of the few temples to escape destruction was Yoshimitsu's Golden Pavilion, which fortunately had been situated well outside the
