Hon. Joni T. Hiramoto is a judge for the Superior Court of Contra Costa County in California.

On March 11, 1998, former Governor Pete Wilson appointed her to Contra Costa County Municipal Court, and in June 1998 she was elevated to the seat of Superior Court Judge through unification.

Judge Hiramoto is Democrat.

She was the former President of the Asian American Bar Association of the Greater Bay Area. She was also associated with San Francisco Women Lawyers Alliance, the Asian Law Caucus and the Bar Association of San Francisco as either an officer or a director.

According to the judge, an attorney's reputation is an important aspect of his/her career. She appreciates the attorney who respects their opposing counsel.
