The Green Line(横浜市営地下鉄グリーンライン) is a railway line of the Yokohama Municipal Subway connecting the 13.1 km from Zhongshan station in Yokohama-Shi, Kanagawa Prefecture to Hiyoshi station in the city of Kohoku Ward (10.7 km underground, 2.4 km above ground section). It is called the Green Line from passing through the hill. The official name is "Yokohama High speed railway line No. 4". The name of the city high-speed railway based on the City Planning Act is "Yokohama International Port Capital Construction Planning City Highway No. 5 Municipal Subway Line 4". The line symbol used in the station numbering is G.

It was opened on March 30, 2008. From the nickname Green Line, it may be abbreviated as GL.


This line is part of the Yokohama Annular Railway (see Gothe for the overall image). The construction was started on January 30, 2001 and officially opened on March 30, 2008. The vehicle was introduced with a type of linear motor drive, with a maximum speed of 80km/h and the highest speed in the linear subway system. There is also the first ground section of the linear subway line (non-operating sectors are located on the ground floor of the seven Subway dark circles in Fukuoka City).

From Zhongshan Station to the Kawawa-cho station, there is a steep 58‰ gradient on this route [3] [1]. It was originally scheduled to be opened in 2007, but it was not possible to obtain the agreement of the owner of the land right of the Hiyoshi-Hiyoshi-Honmachi. In December 2004, the application of an adjudication based on the land expropriation Law was also considered, although a partial opening was investigated.

Then, on November 16, 2006, the applicant was ruled as on December 13, 2008, the Yokohama City Transportation Bureau announced that it would aim to open the whole line at the end of March, 2009 (then, on January 8, 2008, the official opening date was announced on March 30, the same year). Each station had a home door, escalators and large elevators, and a new resting space was set up. In addition, the station collar is set to each station individually, and the gray boat (line color) that the station color enters the Lightning belt 2 lines is installed on the wall of the train stations.

This means that the train will be dashed when approaching, and it will flow in the direction of progress, but it has stopped using it since 2011 because the equipment problems are not solved. The Green Line is from 14:00 to 17:00 on weekdays from the opening day to September 30 (originally planned), "Smile Manor Improvement staff" is deployed in the car for the first time in the country. This is the manners to cede in the seat priority seats are introduced by Yokohama Municipal Subway, because it is not promoted only by automatic broadcasting in the car, there is a purpose that the improvement worker calls to give away the seat to the visitor in the car, and the morality and manners are infiltrated further.

In addition, security guards are also deployed at the same time to avoid trouble with the customer now.

Although it corresponds to the pasmo from the time of opening, it was correspondence only of the counter payment by the automatic ticket ticket machine and the ticketing machine excluding the center South Station and center North station which connected to the Blue line for the pass net Marine card. This line connects via the Kohoku New Town on the JR Yokohama Line of Zhongshan Station and the Toyoko line and Meguro line, as well as establishing a pathway to the Tama area of Yokohama Line and Kohoku New Town in Tsuzuki-ku, Yokohama City.

Some of the commuters who had been commuting from Kohoku New town to the center of the city via the Denentoshi line before the opening of this route transferred to the Meguro line, which was the first train of Hiyoshi station, and led to the easing of the congestion of the rural city line. In the first month after the opening, the average daily forecast of 104,000 people (the initial forecast was average of 137,000 people per day) was significantly less than the average 53,129 people

With the population accumulation in Kohoku New town and the increase of the employment population due to the commercial facilities and the corporate location, the number of passengers per day in fiscal 2015 was almost consistent with the 135,569 recollections, almost as expected. Moreover, it can be said that the effect of lowering the environmental load as an alternative transportation system which changes to the bus which becomes difficult to maintain the schedule by congestion etc. in Yokohama City where the maintenance of the city planning road is delayed has been brought.
