Yoshimasa Tominaga, ambassador to the Democratic Republic of the Congo, was effectively removed Thursday in response to the embezzlement of public funds by an embassy employee.
The Foreign Ministry reprimanded Tominaga, 63, and ordered him to return home.
Earlier this year Shinya Yamada, former third secretary at the embassy in Kinshasa, the capital of the African country, was arrested and indicted for allegedly embezzling about $260,000 in public money from the embassy.
Yamada has also been charged with setting fire last June to the fourth floor of the building where the embassy was located.
The ministry also admonished a 57-year-old first secretary at the embassy, who was responsible for accounting when the embezzlement happened.
