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

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

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

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

Shin-Yokohama Neighborhood Associations took the lead in forming the “Garden City Shin-Yokohama Project Team of the Neighborhood Associations Beautification Environment Department of Shin-Yokohama” and working on greening the walls of the Shin-Yokohama Square Building. Taking advantage of the high visibility of the wall greening, it is used as the starting point for bustling production.
In addition, container flower beds are installed on private land to create a green atmosphere throughout the city.

Rain gardens (*) of different types have been set up at 11 stadium streets, 2 on Shin-Yokohama Chuo-dori, and 16 on F. Marinos Street.

（※） Flowerbeds that draw rainwater around roads and sidewalks into flowerbeds, temporarily store it, and penetrate over time.

We use sewage reclaimed water (*) for watering flowers and greenery in the area.

（※） Most of the sewage treatment water that has been treated as sewage at the Water Reclamation Center is discharged to the sea and rivers, but some are subject to sand filtration and ozone treatment, etc. It is used for many applications such as water for scenic water, toilet washing water, and miscellaneous water.
The sewage reclaimed water used for watering is filtered with sand to further remove invisible fine dirt, and then sterilized with an ozone disinfection facility.

• We arranged the shape of the street trees and carried out pruning such as leaving many branches so that the shade of greenery increases. By creating shades of trees, direct sunlight is blocked and the heat is alleviated.
• 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 to reduce the heat due to 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 finals venue. As a result, it is possible to produce powerful lighting with a sense of realism integrated with the sound.
• Compared to existing lighting, energy saving is achieved by about 35%.
• Light-up lighting outside the venue is full-colored, enabling lighting in various colors, and it can also function as a local landmark that adds color to the city by producing seasonal expressions.

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