Singer-songwriter Ayaka has been chosen to supply the theme song for the animated film "Doraemon: Nobita and the Legend of the Green Giant," which opens in theaters on March 8. The song is titled "Te wo Tsunagou."

Ayaka made the announcement on Monday during a performance at Doshisha University, part of her "school festival tour." For her encore, she appeared on stage holding hands with Doraemon, then sang the song for the first time in public.
