The general limit is 60 km/h except for divided national highways where the limit is 100 km/h. Urban areas are usually zoned at 40 km/h. Limits in Japan are different from most countries by:
- having no separate urban limit, with urban limits being set by zoning rather than statute.
- even outside of urban areas a limit of 40 or 50 is common.
- even for divided highways outside of urban areas a limit of 50 or 60 is common.
- emergency vehicles are not exempt but have a higher speed limit, 80 km/h.
- there are some lower limits set for vehicle classes other than ordinary cars and motorcycles.
