(i) In accordance with the urban area reorganization, roads are to be demolished; this may
adversely affect the peripheral traffic functions, or other conveniences or the daily life of the
nearby residents, and thus the following must be reviewed and evaluated.
○ Refer to traffic variations and regulations, and avoid traffic problems for the peripheral areas
○ If walkways must be maintained, a gangway within structures should be provided in an
appropriate spot within the premises after demolition.
(ii) According to local circumstances and needs, the road will be extended for peripheral traffic
or the environment or parks will be ameliorated. The construction of facilities which are nec-
essary for the community, such as parking areas for bicycles, will be determined based on a
demand survey.
(iii) Open spaces (i.e. public spaces or vacant lots) which are to be constructed under the devel-
opments or projects will be built in harmony with public establishments such as new roads or
parks.
(iv) Using a transparent and effective methodology (e.g. District Plan or City Area Redevelopment
Project), and obtaining agreement with the relevant stakeholders, favorable community devel-
opment will be realized.

2. �e composition of a friendly traffic network
(1) Roads
i) Section roads
○ Ensure at least 2.5 meters for one lane which serves as an important passage within the District
and access to the route, as well as sufficient walking space and plentiful green space
○ Restrict transit traffic from outside of the District, maintain the environment of the urban route area
to ensure roadways with width of 7 meters for each lane so that cars can run smoothly within the
District
○ As described above, in principle, a width of 12 meters must be provided to ensure the sufficient func-
tioning of sidewalks and roadways; provided that if ensuring the appropriate width is impracticable due
to geographical features, functionality will be ensured with a specially-designed sidewalk.
○ A road running to the north and the south within the center of the District is recognized as the
major section road to ensure smooth traffic flow within the District, and to ensure sufficient walking
space, including, at least 2 meters of a specially-designed sidewalk, and to create a green space
with tree-lined street.
• Provide sufficient walking space to ensure pedestrian safety and comfort
• Restrict transit traffic as much as possible to protect the surrounding residential environment or
secured walking environment
• Ensure smooth passage without being congested with people and cars
ii) Other roads
○ In order to ensure pedestrian safety and comfort, roads compatible with the local conditions, such as
roads both for pedestrians and cars, and greenways, as roads that complement or extend the func-
tions of section roads, are to be built.
�e concept of creating a friendly tra�c network
1. �e concept of creating a friendly traffic network
As a friendly traffic network, based on the following concept, roads will be linked with passages or
squares available to the public, in order to create a friendly traffic network which everyone can use
safely and comfortably.
* Ensuring the function of bicycle pathsIn addition to ensuring the function of the traffic network of pedestrians and cars, we commit our-
selves to ensuring a space for a friendly bicycle traffic network in accordance with the “Policy for Con-
ditions of Bicycle Use for Minato City (tentative)” (to be prepared in 2012).

(2) Passages and squares within the premises
i) Pedestrian malls
○ The pedestrian malls are green passageways that constitute the
plentiful green spaces within the northern area (Akasaka/Toranomon
pedestrian mall) and the south area (a walking space that connects
Kamiyacho Station with Roppongi itchome Station)
○ In principle, a width of 5-10 meters is to be provided.
ii) Pedestrian passages
○ The pedestrian passages are to be provided as facilities to enhance
the convenience and ease of getting around within the District. In
the case of geographical differences of elevation, accessibility to the
disabled, etc., will be provided using an access ramp or similar.
○ In principle, a width of at least 2 meters is to be provided.
iii) Specially-designed sidewalks
○ The specially-designed sidewalks are to be provided along the
routes, as spaces that complement or extend the sidewalks.
○ The specially-designed sidewalks will be provided along the routes
that run to the south and the north within the District, to ensure
green and comfortable spaces.
○ In principle, a width of at least 2 meters is to be provided.
iv) Public squares
○ The public squares connect pedestrian networks and are to be provided around subway stations
and intersections.
○ They will also serve as temporary evacuation sites in case of disasters.
v) Subway pedestrian passage
○ The subway pedestrian passages which are connected with subway stations will be provided to en-
hance the safety and convenience of pedestrians.
vi) Car passageways
○ A reduction in car traffic on the road due to connections with many parking lots will improve traffic
conditions and reduce traffic.
○ Basically, car passageways will have a width of 8 meters and be facilities provided within private land
and thus not subject to the Road Traffic Law, being properly managed by each of the owners in ac-
cordance with certain standards.
○ For some car passageways, we should evaluate a possible network in accordance with current pe-
ripheral community development to facilitate smooth car traffic and reduce traffic, respecting the
treatment of preserved trees.
(3) Other
i) Facilities within stations
○ The entrances and exits connected with the subway pedestrian passages will be reconstructed or
extended, and passages within the premises will be made barrier-free.

according to the form, design, or colors of structures by considering sectioned walls or the exterior wall finishes.
○ Create a striking urban landscape→ Promote the creation of a landscape that enables us to enjoy good distant views of the District
as seen from neighboring districts
○ Preserve and develop the landscape composed of structures and road space, taking advantage of land features or establishments along the route
○ Create a symbolic street→ The street running to the south and the north
though the center of the District will be pre-served and developed as a symbolic street. It will be a distinctive and attractive street incorporating structures along the route, using the elegant and comfortable walking space and the reformed and plentiful roadside flora and greenbelts.
○ Put cables underground, reconstruct or repair road signs, and remove illegally parked bicycles

“Creating rich local history and quiet, dignified streets”
Measures (i) Creating dignified streets which take advantage of the regional characteristics
Measures (ii) Creating distinctive and attractive streets that are enjoyable to walk on
Measures (iii) Harmonization with the surrounding landscape of skyscrapers, and promotion of landscape control
The District, featuring historical and cultural establishments within a wide variety of large and small urban areas, has varied and various streets with differences in elevation, and noted greenery. We will preserve and develop these various landscape resources, to create elegant and dignified streets. We will take advantage of the local characteristics of land use on the route, cooperate with neighboring districts, and create distinctive and attractive streets that will be enjoyable for walking.
For a large project, we will create an elegant street in harmony with the peripheral landscape.
○ Create streets taking advantage of local characteristics→ Preserve and develop substantial greenery and historic large trees in shrine, embassies, etc.→ Preserve and re-sculpt the greenery on the slope, accentuating geographical characteristics
○ Create streets that showcase local history and culture→ Preserve neighboring cultural structures (e.g. art museums) representing the community's
personality→ Create streets that take into account the community's history or culture, such as resources
that represent the formation of the community (e.g. the geography and various forms of urban area), and the nature of neighborhood
We will give consideration to the varied geography in the community, noted greenery, and the cultural resources or the community's history, to create more dignified thoroughfares.
We will create distinctive and attractive streets that are enjoyable for walking, which take into account the characteristics of the routes in coop-eration with the surrounding urban areas.
For skyscrapers constructed through developments, we will proceed with the creation of an elegant street in harmonization with the peripheral landscape. We will also make considerations to create a good background landscape of the District as seen from neighboring districts.

“Creating an urban space enriched with varied and plentiful greenery”
A generous amount of flowers and trees, including a significant number of high trees, will
be planted. This will serve to establish a green axis running to the south and north, as well
as another to the east and west, creating a green community of networked lush green
spaces, and making people feel that the urban landscape is embedded into vegetation
throughout the entire community.
We have committed ourselves to creating a community where people congregate and
interact in a green space with its accompanying wildlife.
Measures (i) Forming a green axis and locations with accumulated vegetationWe will facilitate the “Green axes” running to the south and north as well as to the east
and west, and spots with verdant greenery covering a large area, to create an attractive
space.
○ Create high-quality “green axes”→ Greenbelts of a high quality on the roads extending to the south and the north through the
center of the District, and sidewalks crossing from the east to west○ Create spots with verdant greenery covering a large area→ Evaluate urban planning measures to realize “spots with verdant greenery” within Reinan-
zaka Park
Measures (ii) Ensuring and organizing a network of various greenery that makes people feel closer to nature
We will create areas of greenery in large squares or greenbelts, and “green spots” from
children’s parks or big trees, to create a large green network, and ensure uninterrupted
stretches of varied greenery along transportation and pedestrian routes.
○ Preserve and reorganize noted spots with greenery→ Preserve and reorganize noted greenery spots that have been developed in the community
for a long period of time→ Reinforce and evaluate measures to support the designated preserved trees pursuant to the
“Minato City Ordinance for Preservation of Greenery”○ Create familiar spaces with varied greenery→ Facilitate the development of parks or greenbelts→ Tree planting on sidewalks, pedestrian passages, specially-designed sidewalks, and public
squares→ Facilitate tree planting for structures (wall greening, roof greening)
○ Networking of varied greenery→ Network the varied greenery to create “green axes” or “spots with verdant greenery”
Measures (iii) Providing and developing green spaces to improve the community’s relationship with natureWe will facilitate an active community undertaking for maintenance and management of
our greenery in cooperation with the community. We plan to carry out this undertaking in a
way that enables citizens and visitors to experience the nature and its accompanying wild-
life, in hopes that the green spaces help create a community with closer bonds.
○ Facilitate the proper maintenance and management of friendly green spaces○ Strengthen local community bonds by utilizing a greenery adoption program, community gar-
dens, or roof greening or biotopes○ Address efforts to diversify wildlife through an improved environment in which creatures inhabit or
