Misa Aika (born November 2, 1976) is a Japanese talent hailing from Kurume City, Fukuoka Prefecture. In January 1993, she made her CD debut under the name Kumiko Fujiwara from Maikaru Hummingbird.

Her debut song "Junai" was used in a commercial for Johnson & Johnson Baby Lotion, although she did not appear in the actual commercial. While the song garnered attention, her debut single did not sell well and her planned second single for June was shelved. She wrote the lyrics for the song herself.
