He later apologized over what he said were "misleading" remarks.

The firing comes as Japan prepares to welcome the U.S. and other allies for the Group of 7 meeting in May.
Japan is the only G-7 country that doesn’t legally recognize same-sex marriage or civil unions.
Another one of Kishida’s aides resigned late last year after making anti-LGBTQ remarks.
Kishida’s approval ratings are also underwater after a series of resignations as national support for same-sex marriage is growing, opinion polls have showed.
Last November, a Tokyo court upheld a ban on same-sex marriage but also said having no legal protection for gay or lesbian couples was a violation of human rights.
