"Nada Sōsō" (涙そうそう, Great Tears Are Spilling) is a song written by Japanese band Begin and singer Ryoko Moriyama.

[1] Moriyama re-released the song as the second A-side of the single "Satōkibi-batake/Nada Sōsō" in 2001, after Rimi Natsukawa's version had become popular.

[5] The single features two B-sides: "Kariyushi no Yoru" (かりゆしの夜, Harmony with Nature Night) and "Hana (Live Version)" (花, Flowers).

[7] Due to the song's popularity, it became the focus of the "Nada Sōsō Project" by Japanese television company TBS.

The single charted steadily until next year's Kōhaku Uta Gassen, where Natsukawa, Begin and Ryoko Moriyama performed the song together.

The song has been recorded in cello, erhu, harmonica, harp, guitar, koto, music box, piano and violin versions, amongst others.

It has also been covered by Yonashiro Sho 【The Leader of the Japanese boys group (JO1)】‹Pre-Debut cover› and also overseas artists, such as Hawaiian Kealiʻi Reichel (as "Ka Nohona Pili Kai" in Hawaiian) and New Zealander Hayley Westenra, who sung a classical crossover rendition in English, and Korean singer Memory (Maeng Yu Na 맹유나), (as Nunmulee Naeyo (눈물이 나요) in Korean).
