[3][4] Major league baseball player Ichiro Suzuki of the Seattle Mariners chose Sayuri Ishikawa's "Amagi-goe" as an at-bat walk-up song in 2008 along with Misia's "Ishin Denshin" and "Royal Chocolate Flush".

In 2015, Ishikawa recorded "Chanto Iwanakya Aisanai", the ending theme of the Lupin the 3rd Part IV anime.

[8] Ishikawa's first Kōhaku Uta Gassen appearance was in 1977, four years after her debut and following the hit of her signature song "Tsugaru Kaikyō Fuyugeshiki".

2017 marked her 40th appearance in total, and 36th consecutive year in the ever popular annual event, which is a record for a female artist.

She missed the 34th edition in 1983 as she was heavily pregnant, though she did attend the show and appeared as a guest, cheering the red (female) group.
