Politicians from the devastated northeast repeatedly express exasperation at the slow pace of reconstruction and a lack of leadership from Tokyo.
An official from Fukushima prefecture said needs in the area around the crippled nuclear plant were not being met.
"We need lots of money for decontamination of radiation, but the implementation of budgeted projects tends to be delayed," Chizuo Hayashi, from the Fukushima reconstruction bureau, told AFP Thursday.
"We residents in the disaster-hit area hope the reconstruction budget will be used primarily for rebuilding our communities," he added.
The figures came in a government-commissioned 141-page audit released last week detailing 192 public projects purportedly aimed at reconstruction and disaster prevention.
"The purpose of the report is to expose to the eyes of the public details of the budgeted projects," board of audit official Tetsuya Hosokawa said Thursday.
"We didn't say which projects were appropriate and which were not, but following criticism by media and the public, each ministry may review their budgeted projects," he said.
