The Aso volcano crater area is currently under Level 2 eruption warning with a 1km restriction radius around Nakadake crater. Visitors can access the crater viewing area (山上広場) and use the shuttle bus/crater road during operating hours, but cannot enter the restricted 1km zone around the crater itself. Today is late autumn (November 11), so the road operates 8:30 AM to 5:30 PM with gates closing at 5:00 PM.
- Restricted radius: 1,000 m
- Crater shuttle bus: Operating
- Areas affected: Nakadake crater (中岳火口), Crater rim area (火口周辺)
Traffic/Parking (schedule estimate, not live sensor data): No particular reason to expect crowding right now -- a weekday outside peak season and peak hours.
