"We hope that this year the invitations [to visit Russia] to the heads of upper and lower houses of the Japanese parliament will be accepted," the Russian ambassador to Tokyo said.
"There is a very good idea, coordinated between the two sides, for the senators, parliamentarians to oversee and support specific cooperation projects, including on the regional level," the diplomat added.
Since 2016, the Russian-Japanese relations have been experiencing a dynamic development. In mid-December 2016, Russian President Vladimir Putin visited Japan where the sides signed an unprecedented number of documents on bilateral cooperation.
In January, Japanese Prime Minister Shinzo Abe said he would visit Russia in April to discuss the peace treaty with Russia. Abe's second visit is scheduled for September.
