Putin visits disputed Kuril island; Japan protests
Putin’s visit to Iturup has returned a long-running territorial dispute to the center of Japan-Russia relations.

What happened
Vladimir Putin made his first visit to Iturup, one of the Russia-administered Kuril Islands also claimed by Japan. He toured a fish-processing plant, hospital and school, and met residents and the Sakhalin governor. Japan lodged a diplomatic protest and summoned Russia’s ambassador, saying the trip hindered relations.

- What makes Putin’s trip notable?
- He is the first Russian president to visit the island chain; Dmitry Medvedev was the first Russian leader to visit.
- Why does Moscow value the islands?
- The archipelago has fishing grounds and minerals, and its location near Japan gives Russia a military foothold in the Pacific.

Support and opposition
Who supports this, and why
Russian government — The islands’ sovereignty was settled by postwar international documents, and Japan changed its earlier approach to relations.
Who opposes this, and why
Japanese government — The four islands are historically and legally Japanese territory, so a presidential visit there cannot be accepted.
The catch
Coverage does not show whether either government will take steps beyond Japan’s diplomatic protest.
