Initiatives by Yokohama, an environmentally advanced city full of flowers and greenery in central Shin-Yokohama

From 2019 to 2020, the Yokohama International Stadium will host the Rugby World Cup 2019 TM and the Tokyo 2020 Olympic and Paralympic Games. In the central Shin-Yokohama area around the Yokohama International Stadium, which is visited by many people from Japan and abroad, we are developing initiatives to realize Yokohama's "environmentally advanced city full of flowers and greenery" in cooperation with related ward offices.

During the Rugby World Cup, the following flowers and greenery are installed on the street tree planting zone, Shin-Yokohama Ekimae Park, and the pedestrian deck in front of Shin-Yokohama Station to create gorgeousness.

• 20 container flower beds with the image of participating teams
• 21 container flower beds colored with flowers
• 8 new brick flower beds
• 8 existing brick flower beds
• Eight flower towers
• 108 hanging baskets produced in collaboration with Neighborhood Associations
• 15 container flower beds with hanging

Neighborhood Associations Shin-Yokohama Project Team led the formation of the Shin-Yokohama Project Team, a project team of Shin-YokohamaNeighborhood Associations Beautification Environment Department, which worked on greening the walls of the Shin-Yokohama Square Building. Taking advantage of the high visibility of wall greening, it is used as the starting point for lively production.
In addition, container flower beds are set up on private land to create a green atmosphere throughout the city.

We have different types of rain gardens (*) for 11 locations on Stadium Street, 2 on Shin-Yokohama Chuo-dori, and 16 locations on F. Marinos Street.

（※） Flowerbed that draws rainwater around roads and sidewalks, into flower beds, temporarily stores, and penetrate over time.

Sewage recycled water (*) is used to water flowers and greenery in the area.

（※） Most of the sewage treatment water that has been treated at the Water Reclamation Center is discharged into the sea and rivers, but some of them is sand filtration and ozone treatment. It is used for many purposes such as miscellaneous water.
Sewage recycled water used for watering is filtered with sand to further remove invisible fine dirt, and then sterilized with an ozone disinfection facility.

• We adjusted the tree shape of the street trees so that the shade of green would increase and prune. By creating shades of trees, direct sunlight is blocked and heat is reduced.
• In cooperation with the demonstration experiment of the Ministry of Land, Infrastructure, Transport and Tourism, tunnel-type and bench-type heat mitigation facilities have been installed at Shin-Yokohama Ekimae Park.
• The ground of the East Gate Bridge of Yokohama International Stadium is paved with heat shielding to reduce the heat caused by the reflection.

• The lighting for the competition has been converted to LED to ensure the necessary illuminance according to the standards of the Rugby World Cup final match venue. This makes it possible to produce powerful lighting with a sense of realism that is integrated with sound.
• Compared to existing lighting, it achieves approximately 35% of energy saving.
• The off-site lighting is fully colored, allowing it to be turned on in various colors, and it can also function as a regional landmark that adds color to the city through productions that express the season.

• We have replaced 30 sewer manholes on the sidewalk on Shin-Yokohama Chuo-dori and Arena Street with design manholes of Rugby World Cup 2019TM specifications. The installation period is until early December.
