Zone 4 Evacuation
Zone 4 has two designated routes. Use the route nearer to your position at the time of the notice; do not cross the corridor to reach a preferred route.
Route 4A (primary)
North-west along Ushiba-dori to the ridge road. Assembly point: Ushiba Ridge Assembly Ground.
Route 4B (secondary)
East via the Sakai river crossing. Assembly point: Sakai East Sports Centre. Route 4B closes in high water; signage at the crossing is authoritative.
During an active notice
Vehicles are prohibited on both routes during an active notice. Assisted-evacuation vehicles operate from registered addresses only — register in advance.
Zone 4 is served by the Kanto North Regional Office.
