ニシヨロヲカケアン
Ainu「晴れ日」
Batchelor 1938 Nishoro-okake-an (p.326) explicitly means weather clearing; Hirayama part 3 quotes this comparison. Tamura nisor supports the shortened first component. nisoro okake an preserves the historical vowel more closely. The whole expression has dictionary support despite zero modern corpus matches.
