In October 1993, Japanese Prime Minister Morihiro Hosokawa made an official visit to Moscow—the first by a Japanese premier in 20 years—meeting with Russian President Boris Yeltsin. The centerpiece of their talks was the decades-old territorial dispute over the Southern Kuril Islands (known in Japan as the Northern Territories: Etorofu, Kunashiri, Shikotan, and the Habomai islets), seized by the USSR in 1945.
The 1993 meeting marked a brief thaw after the 1956 Joint Declaration (where USSR offered to return Shikotan and Habomai *after* a peace treaty) stalled. However, domestic opposition in both countries, leadership changes (Hosokawa resigned in 1994), and hardening positions prevented progress. Subsequent summits (1997, 1998, 2001, 2018, 2019) similarly failed to bridge the gap.
As of 2024, the islands remain under Russian administration, hosting military installations and a civilian population of ~20,000. Japan continues to claim them, and the peace treaty remains elusive—a Cold War relic persisting in 21st-century geopolitics.
