Ashikaga Yoshimasa unexpectedly became shogun at a young age, after his older brother Yoshikatsu died under possibly suspicious circumstances, and it is clear that he never really wanted the responsibility that came with the position. He was more interested in artistic and spiritual pursuits, and is known today not only for his mismanagement of the Ōnin War, but also for his patronage of the artistic traditions that developed into (now) classical Higashiyama culture. These traditions draw on Zen Buddhism and the concept of wabi-sabi (imperfection and impermanence), and include the tea ceremony, flower arranging, Noh theatre, ink painting, and certain forms of poetry. Before the outbreak of the Ōnin War, Yoshimasa ordered the construction of a new villa that he planned to (and eventually did) retire to, now called the Silver Pavilion (Ginkaku-ji), in contrast with the older and more ornate Golden Pavilion (Kinkaku-ji) commissioned by his grandfather Ashikaga Yoshimitsu. The understated and sometimes sorrowful nature of Higashiyama culture gains an extra poignancy upon learning of its origins in the bloody, and ultimately futile, Ōnin War.
