The Foreign Ministry dismissed a former consul general in Frankfurt on Wednesday after finding he wined and dined local corporate officials with taxpayers' money to secure a job for his son.

Takeshi Kamiyama, 60, spent ¥760,000 ($6,700) on meals with the officials and to buy them presents between August 2015 and October this year until a whistle-blower reported the misconduct, the ministry said.

Kamiyama has since paid back the entire sum to the ministry, but it may still lodge a criminal complaint against him in light of the grave nature of the wrongdoing.

Kamiyama entered the ministry in 1979 and previously worked at Japanese diplomatic missions in Portugal and Austria.
