in the Man'yōshū. Following Shiki's death, in the Taishō period (1912–26), Mokichi Saitō and his friends began publishing a magazine, Araragi, which praised the Man'yōshū. Using their magazine they spread their influence throughout the country. Their modernization aside, in the court the old traditions still prevailed. The court continues to hold many utakai (waka reading parties) both officially and privately. The utakai that the Emperor holds on the first of the year is called Utakai Hajime and it is an important event for waka poets; the Emperor himself releases a single tanka for the public's perusal. After World War II, waka began to be considered out-of-date, but since the late 1980s it has revived under the example of contemporary poets, such as Tawara Machi. With her 1987 bestselling collection Salad Anniversary, the poet has been credited with revitalizing the tanka for modern audiences. Today there are many circles of tanka poets. Many newspapers have a weekly tanka column, and there are many professional and amateur tanka poets; Makoto Ōoka's poetry column was published seven days a week for more than 20 years on the front page of Asahi Shimbun. As a parting gesture, outgoing PM Jun'ichirō Koizumi wrote a tanka to thank his supporters. The Japanese imperial family continue to write tanka for the New Year. Poetic culture In ancient times, it was a custom between two writers to exchange waka instead of letters in prose. In particular, it was common between lovers. Reflecting this custom, five of the twenty volumes of the Kokin Wakashū gathered waka for love. In the Heian period the lovers would exchange waka in the morning when lovers met at the woman's home. The exchanged waka were called Kinuginu (後朝), because it was thought the man wanted to stay with his lover and when the sun rose he had almost no time to put on his clothes on which he had lain instead of a mattress (it being the custom in those days). Works of this period, The Pillow Book and The Tale of Genji provide us with such examples in the life of aristocrats. Murasaki Shikibu uses 795 waka in her The Tale of Genji as waka her characters made in the story. Some of these are her own, although most are taken from existing sources. Shortly, making and reciting waka became a part of aristocratic culture. They recited a part of appropriate waka
