Russia "indefinitely" banned 63 Japanese citizens including Prime Minister Fumio Kishida from entry, Russian state news agency RIA Novosti reported Wednesday.
Members of Kishida's cabinet, including Foreign Minister Yoshimasa Hayashi, Defense Minister Nobuo Kishi, and Finance Minister Shunichi Suzuki have also been barred from entering the country, as well as members of the parliament, and the military, RIA reported.
"The administration of Fumio Kishida launched an unprecedented anti-Russian campaign, allows unacceptable rhetoric against the Russian Federation, including slander and direct threats," Russia's Foreign Ministry said in a statement, according to RIA.
"It is echoed by public figures, experts and media representatives of Japan, who are completely engaged in the attitudes of the West towards our country."
Since March, Japan has introduced a series of sanctions against Russia including freezing the assets of President Vladimir Putin and his family members in response to Russia’s invasion of Ukraine.
Some background: Last week, Russia warned Japan of "retaliatory measures" if it expands joint naval exercises with the United States near Russia's eastern borders.
The threat was the latest salvo from Moscow, which has been angered by Japan's support for Ukraine and its growing ties with NATO countries.
