Everything is not ephemeral as The Wonderful Worlds of 100 Wakas (Japan Times, December 30, 2012) by Stuart Varnam-Atkin proves.
Author reminds us that for 15 centuries people have beens writing 'poems of 5-7-5-7-7 syllabes each'.
One of the best known collections is "Ogura Hyakunin Isshu" that overwhelmingly best-known "Ogura Hyakunin Isshu" anthology of 100 poems "compiled in Kyoto's Ogura district by Fujiwara no Teika (or Sadaie, 1162-1241)" writes Stuart Varnam-Atkin.
Hyakunin Isshu cards became base of Uta-garuta card games like 'Turn up the monk'.
These games and reading of poems are part of New Year's traditions in Japan.
