Hideo ARAI, in his paper, 'A Little Thought on 'Ochimizu that Tsukuyomi Has'' (in 'Nihon Bungei Kenkyu' (Japanese Literary Studies), April, 1991) pointed out from the standpoint of folklore that several rituals that obtain 'wakamizu,' which expels evil atmosphere for the year, are performed on New Year's Day in various localities in Japan, and that 'Wakamizu wo sonau' (offering of wakamizu) performed on the first day of spring as an annual event during the Heian period is observed in records such as "The Engishiki" (an ancient book for codes and procedures on national rites and prayers) "Nenchu gyoji hisho" (record of annual events) and issho (lost book) "月舊記."
新井秀夫は、論文「「月夜見の持てるをち水」小考」（「日本文芸研究」1991年4月）において、民俗学の見地から、元旦に一年の邪気を払う「若水」を汲む行事が日本各地で多数採取されていること、そして『延喜式』『年中行事秘抄』や佚書『月舊記』などの文献に平安時代の年中行事として、立春の日に行われる「供若水」が見られることを指摘している。
