The Diet has approved a ¥4.11 trillion supplementary budget to stimulate an economy dampened by sluggish growth amid weak consumer demand and business investment.

The second supplementary budget for the fiscal year through March was approved Tuesday by the Upper House after clearing the Lower House last week. The ruling Liberal Democratic Party and its junior coalition partner, Komeito, hold a majority in both chambers.

Most of the new money will be used to fund part of a roughly ¥28 trillion economic stimulus package approved by the Cabinet in August, including infrastructure investment and enhanced welfare services.
