From the mid-Heian period, amid social anxiety and the approach of the Latter Age of the Dharma (entered 1052), faith in Amida Buddha surged. The "market saint" Kūya (903–972) popularized the nenbutsu among the common people of Kyoto, while the Tendai monk Genshin (942–1017) systematized Pure Land practice in his Ōjōyōshū of 985, vividly depicting hell and paradise. Amida halls such as Byōdō-in's Phoenix Hall (1053) proliferated, paving the way for the later Pure Land schools of Hōnen and Shinran.

After the abolition of embassies to Tang China (894, proposed by Sugawara no Michizane), Japan digested Chinese culture and developed its own aristocratic culture in the 10th-11th centuries, peaking under Fujiwara regent rule. Kana script enabled vernacular literature: Ki no Tsurayuki's "Tosa Diary," Murasaki Shikibu's "Tale of Genji" (world's oldest long novel), Sei Shōnagon's "Pillow Book," Izumi Shikibu's diary, and the "Kokin Wakashū" (905). Shinden-zukuri architecture, twelve-layered kimono, Yamato-e painting, and wayō calligraphy (Three Traces) flourished. Pure Land faith spread Amida imagery.

Culture of the late 11th-12th centuries under retired emperors Shirakawa, Toba, and Go-Shirakawa. Built on national culture but infused with dynamic energy from Pure Land Buddhism's rural spread and the rising warrior class. Amida halls proliferated: Byōdō-in Phoenix Hall (1053, Fujiwara no Yorimichi), Chūson-ji Golden Hall (1124, Northern Fujiwara), and Fuki-dera. Picture scrolls flourished: Tale of Genji Scrolls, Shigi-san Engi, Ban Dainagon Ekotoba, and the Chōjū-giga animal caricatures. Go-Shirakawa compiled the imayō song anthology "Ryōjin Hishō." Setsuwa collections like "Konjaku Monogatari" abounded.
