It is estimated to be a work made during the Tenbun era (1532 to 1555) from a genealogy in the opening page, and it contains the entries of three years which were not included in the contents table (or Hojobon) either, therefore as well as Yoshikawabon, the manuscripts seem to have been collected, revised, and enlarged more after the Tenbun era in the Shimazu family too.
巻首にある系図からは天文(元号)年間（1532～1555年）と推定され、更に冒頭の目録に無い3年分（北条本にもない）が含まれていることなどから、吉川本同様に島津家においても天文年間以降、更に収集と補訂が行われて成立したと見られている。
