- The president personally visited the Kuril Islands for the first time, TASS reported.

- Prior to this, the heads of the Russian state and government had visited the Kurils five times altogether.

- Dmitry Medvedev made four trips: in 2010 as president, and in 2012, 2015 and 2019 as prime minister.

- In 2021, Prime Minister Mikhail Mishustin visited Iturup.

- Japan has expressed a "decisive protest" to Russia over Putin's visit to the Kuril island of Iturup, according to a statement from the head of the Japanese Foreign Ministry.

- The ministry also asserted that all the "northern territories," as Tokyo refers to the southern part of the Kuril Islands, including Iturup, are "inherently [Japanese] territory from both historical and legal points of view."

- The Russian Foreign Ministry has repeatedly emphasized that Russia's sovereignty over these territories, which has the appropriate international legal basis, is beyond doubt.
