How Japanese tolls work
Most expressways (高速道路, kōsoku-dōro) are toll-operated by NEXCO East, Central, West and regional operators. The standard rate for a passenger car is roughly ¥25 per km, so a Tokyo–Osaka run costs well over ¥10,000 one way. Toll booths accept cash or ETC (electronic toll collection) — cash is slower, and only ETC gets the night and weekend toll discounts.
