Her name is Lenore Kwock.
From his obit in the Star Advertiser:
Inouye's closest re-election challenge came in 1992 when his Republican opponent, state Sen. Rick Reed of Maui, obtained a tape recording of Inouye's longtime hairstylist, Lenore Kwock, claiming Inouye had pressured her into sex in 1975 and later sexually harassed her. Reed was criticized by Kwock and the leaders of his own party for going public with the steamy allegations in campaign advertisements. Inouye denied the claims and won re-election with 54 percent of the vote, the lowest victory margin of his career.
