I read Toshinori Tsubouchi 'Morokuhaiku Masumasusakan' (Iwanamishoten.)He shows three kaikus as the revolutionary works in haiku history.
'Furuikeya Kawazutobikomu Mizunooto' Basho
'Nnohanaya Tsukihahigashini Hiwanishini' Muson
'Kakikueba Kaneganarunaru Horyuji' Shiki
Now robai and suisen have their flowers.
