The average annual income reported by members of both houses of the Diet dropped to a record-low 23.59 million yen in 2004, down 5 percent from the previous low of 24.81 million yen in 2003, according to a tally by Kyodo News based on annual reports released Monday.

This was the third consecutive year in which the average reported income posted a record low since the disclosure of lawmakers' assets was made mandatory in 1993.

Few reported huge gains on land and other assets, and there was a cut in bonuses.
