Born and raised in Japan, Mayumi began taking lessons on the electric organ at the Yamaha Music School when she was only four years old. She continued her studies through college where she majored in electric organ. Upon graduation, Mayumi became an instructor of electric organ at the Yamaha Music School. In 1992, while teaching there, she won the Gold Medal and the 100,000 Yen (U.S. $10,000) prize in the "Classical Category) at Yamaha Japanese National Electone Festival & Competition. She was subsequently chosen to represent Japan in the Yamaha International Electone Competition where she won the Bronze Medal. In each case she played Rachmaninoff's very demanding "Symphonic Dances."

Since then, Mayumi has given a number of solo concerts in and around Tokyo. Other performances include collaborations with various choral and opera groups including Toyama Civic Opera, Ibaraki and Takatsuki-shi Civic Operas, playing Humperdinck's Hänsel and Gretel and Onna wa Suteki. In the coral music area, she has collaborated with Keio University and Nihon Joshidai in Dovorak's Requiem and Fauré's Requiem, and with Nihon Gakuen where she played the organ transcription of Rigoletto by Verdi. In the last three years Keiko and Mayumi have collaborated and performed together six times. Fortunately for we Northern Californians, four of those performances were here in the Bay Area. Perhaps the most notable was their wonderful production of Gounod's Roméo et Juliette, held last fall at Santa Clara University, in which Gregory Fair also appeared. The other two collaborations were staged in Japan.
