The three most frequently commented texts of the classical literary canon are Kokin wakashu or KKS, Ise monogatari or The Tales of Ise, and Genji monogatari or The Tale of Genji. Imperial waka anthologies for the three centuries after KKS were ignored by commentators until the eighteenth century; the same is true for The Tale of Sagoromo, a narrative fiction the waka of which were considered comparable to those of Genji in late Heian and Kamakura times. One factor must be that KKS and Tales of Ise themselves incorporate distinctive forms of commentary. KKS can be defined in fact as a corpus of cited poems framed by two kinds of editorial comments and two "prefaces". The earliest extant commentaries on The Tales of Ise inclined toward extravagant allegoresis incorporating strains of Esoteric and Tantric Buddhism and Shinto that flourished in the thirteenth and fourteenth centuries, often intertwined with heterodox KKS commentaries of a similar bent.

Hyakunin isshu, a collection of one hundred poems by one hundred poets who lived from the seventh century to the thirteen century, was compiled by Fujiwara no Teika. It contains forty-three love poems, nearly half of the collection and an extremely high percentage compared to that in imperial waka anthologies. In the Edo period the Hyakunin isshu came to represent the entire tradition of Heian court poetry, and it saw a sudden increase in readership, particularly due to the new print culture, which enabled people from all classes to educate themselves. The Hyakunin isshu has taken many forms. During the Pacific War a collection called Aikoku hyakunin isshu or The Patriotic Hyakunin isshu appeared, praising the emperor and encouraging loyalty to the nation and the throne. Today Hyakunin isshu is one of the most familiar pieces of classical literature in Japan and without a doubt will reappear in the future in many new forms.
