[Japan] Protests: Peaceful protest

Summary

Single-source ACLED detection — awaiting independent verification. On April 5, 2025, protesters gathered at Shinjuku station in Tokyo to demonstrate against U.S. military base construction in Henoko, Okinawa, organized by the Okinawa One-Tsubo Anti-War Landowners Association Kanto Block. The event was characterized as a peaceful, low-severity protest.

Supply chain impact

No commodities or chokepoints are directly mapped to this event; second-order effects depend on how the situation escalates. The protest location at Shinjuku station, a major Tokyo transit hub, could potentially disrupt local transportation flows if demonstrations expand, though the peaceful nature and limited scale suggest minimal immediate impact on regional supply chains.

Watch points

• Monitor for escalation or expansion of anti-base protests across Japan that could affect broader transportation networks
• Track any policy responses from Japanese or U.S. authorities regarding the Henoko base construction timeline
