On May 29, Japanese Prime Minister Kishida Fumio said that his son, Kishida Shotaro, would resign as assistant.
Kishida Shotaro previously posted a photo with a relative pretending to hold a press conference at the official palace, causing backlash from the public.
Reuters quoted Prime Minister Kishida as saying that Shotaro Kishida will resign his assistant from 1.6, due to " inappropriate" behavior at the official palace.
Last week, a weekly magazine published photos of Shotaro Kishida and his relatives pretending to hold a press conference on the podium where the prime minister often stands.
"Shotaro Kishida's behavior in public spaces is inappropriate for a person in the position of political assistant. I have decided to replace Shotaro Kishida," the prime minister said.
The move comes at a time of disadvantage for Prime Minister Kishida, in the context of him being criticized by the opposition.
seiji Osaka, senior lawmaker for Japan's largest opposition party - the Democratic candidate for Japan - said the impeachment should have come earlier, according to Kyodo news agency.
"It's too late. I suspect Prime Minister Kishida has appointed someone unable to the position of prime minister's assistant," said Mr. Osaka.
