Assets declared by Prime Minister Shinzo Abe, his 17 Cabinet ministers and their immediate family members averaged 91.36 million yen at the time his government was formed in September, documents they submitted showed Thursday.
Foreign Minister Taro Aso topped the asset list with 490.55 million yen, while Abe was third at 147.9 million yen and Defense Agency chief Fumio Kyuma was at the bottom with 20.91 million yen.
Ministers have been required to disclose their assets since 1984, after the late Prime Minister Kakuei Tanaka was convicted in the Lockheed bribery scandal. However, critics say the current disclosure requirements do not provide a clear picture and sometimes may not show the market value of what they actually own.
