Japan's economy minister has been accused in a popular magazine of accepting bribes, but he has denied any wrongdoing and promised an investigation.

The Weekly Bunshun magazine reported Thursday that Economy and Fiscal Minister Akira Amari and his aides allegedly accepted 12 million yen ($103,000) in cash and hospitality from a construction company near Tokyo over the past three years.

The magazine said the money was in exchange for the Amari office's help in settling a dispute between the company and a housing development organization.

Amari is one of most trusted member of Prime Minister Shinzo Abe's Cabinet and served Japan's top negotiator in the 12-nation Trans-Pacific Partnership trade pact.

Amari promised an internal investigation in the case. He does not face a criminal investigation.
