The waka poems in this collection were selected by Monk Jaku-en＜ 寂延＞ in 1233. All
the authors of these poems are related to Ise Country in some way and most of the works in this collection are associated with Ise Jingu Shrine. Although this collection originally consists of 20 volumes and more than 1,000 poems are included in total, more than a half of them have been lost. Now we have only 497 poems carried in seven volumes (three spring volumes, one summer volume, and three fall volumes). Jaku-en is a Shinto priest and his lay name is Naganobu ARAKIDA＜荒木田長延＞. He is a son of Sei-cho ARAKIDA＜荒木田成長＞, the first priest of Ise Jingu Shrine. The source of the poems annotated here is the oldest copy kept in Tenri Library.
