蝦夷方言藻汐草

Asinno is documented as an adverb “newly”, and cup as “month/moon”. Hirayama repeats the source expression under 上旬, but an independent definition of asinno cup as the first ten days has not been located. Asinnocup tests joining. Asir cup and asircup are lexical comparisons for a new moon; the corpus also uses asir cup for next month. Their adjective differs from asinno. The proposed division is retained with lower confidence; no precise day interval or historical pronunciation follows from these comparisons.
