In order to alleviate traffic congestion on the Tokyo Bay Aqua Line connecting Chiba and Kanagawa prefectures, the Ministry of Land, Infrastructure, Transport and Tourism and other organizations plan to introduce a system to vary tolls according to the time of day on a trial basis from this summer to March next year. It is operated on Saturdays, Sundays, and holidays, and during some afternoon hours, 3 yen will be added to the current rate, and 400 yen will be discounted at night.

With subsidies from the national government and Chiba Prefecture, the Tokyo Bay Aqua Line fare has been uniformly reduced to 800 yen for cars equipped with ETC, but the Ministry of Land, Infrastructure, Transport and Tourism, NEXCO East Japan, and Chiba Prefecture plan to introduce a system called "road pricing" that fluctuates the fare according to the time of day on Saturdays, Sundays, and holidays to alleviate traffic congestion.

During the hours from 1 p.m. to 8 p.m., the fare will be increased by 400 yen to 1200,8 yen,
while the time between 0:200 p.m. and midnight will be discounted by 600 yen to 800 yen.
▽ Other times of the year, it will remain at 7 yen.

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and other organizations plan to implement this system on a trial basis as early as late July and until March next year, and after verifying its effectiveness, they will consider whether to introduce it on a full-scale basis.

Efforts to make a difference in road tolls depending on the time of day have been implemented overseas in the United Kingdom and Singapore, and in Japan, they were implemented with the aim of alleviating traffic congestion on the Metropolitan Expressway during the Tokyo Olympic and Paralympic Games held in 3.
