History

Historical Context

In 1972 the United States returned Okinawa to Japan under the 1971 Reversion Agreement, which required a $320 million payment and kept U.S. bases operating. The 2024 Shanghai knife attack on Japanese diners and Beijing’s retaliatory steps revived the lingering Sino-Japanese tension rooted in that reversion, prompting tighter security and calls for multilateral dialogue.
