in volume seven of the kokin-wakashu , eighteen wakas out of twenty-two gaka were made on the occasion of concrete celebrations of specific individuals (most of them for longevity , but some were for celebrating birth .) , the author is not known for the first four wakas and they seem to have been made in an older time and under a situation which is not known . ところで、古今和歌集巻七の賀歌22首のうち18首は、特定の個人の具体的な祝い（ほとんどが算賀だが出生慶賀もある）に際して詠まれたものだが、最初の4首は読み人知らずで、作歌年代も古いと見られ、歌が作られた事情もわからない。
it was not much different from innocho kudashibumi , which was issued by in no cho to specific individuals , except that inshi (official of the in no cho , or retired emperor ' s office ) equal to or below the rank of betto (superintendent ) set their signature and that it took a form of cho in accordance with kushiki-ryo (law on state documentary forms in the yoro code ) or ritsuryo law . 別当以下院司が署名を行われ、公式令 (律令法)に則った牒の書式を取っていることを除けば、院庁より特定の個人に向けて出された院庁下文との大きな違いは無い。
