It seems that Yuko Tomita（とみたゆう子）has ranged somewhat among pop, City Pop and AOR but for this one particular song, she may have also dabbled a bit into the synthpop as well.
"Yanagi ni Dakarete" (Embraced by the Willows) begins with a cute synthesizer and then Tomita's coquettish vocals come in for a pop song that fills in with a whole number of synthetic sounds. Sounds rather Sakamoto-esque. Although Tomita has often helped out in creating her songs, for this one, Miku/Mirai Maeda（前田未来）and Yoshihide Maeda（前田義秀）took care of words and music respectively. The song was a track on Tomita's first album "Colours" released in September 1981.
