The general limit is 60 km/h (37.3 mph) except for divided national highways where the limit is normally 100 km/h (62.1 mph). Urban areas are usually zoned at 40 km/h (24.9 mph).
Limits in Japan are different from most countries:
having no separate urban limit; urban limits are set by zoning rather than statute.
outside of urban areas a limit of 40 km/h (24.9 mph) or 50 km/h (31.1 mph) is common.
for divided highways outside of urban areas a limit of 50 km/h (31.1 mph) or 60 km/h (37.3 mph) is common.
emergency vehicles are not exempt but have a higher speed limit, 80 km/h (49.7 mph).
lower limits are set for smaller vehicle classes other than ordinary cars and motorcycles.
