Site Information Harumi Harumi, the artificial land reclaimed in 1929, is a small island facing Tokyo Bay. The history of Harumi closely related with the industrial evolution of Tokyo. After the WW2, Tokyo rapidly recover and started creating the basis of the current metropolitan core, and Harumi was one of the key features. During high economic growth from 1950s to 1970s, Harumi apartments was constructed in 1958, designed by famous Japanese architect Kunio Maekawa, to fulfill the enormous demand of affordable housing for increasing number of workers and families in Tokyo. On the same time, Tokyo International Trade Fair was also constructed in 1959 which held various types of forums introducing new inventions and spectacular industrial evolutions. Finally, Harumi Passenger Ship

Terminal was constructed in 1990, as a new hub for ferry networks connecting Tokyo Bay to places around the world. However, since 1990s, Tokyo Bay rapidly enhanced its potential as a residential area while its industrial feature gradually declined. Harumi, which was a symbol of Tokyo’s industrial evolution, nowadays it is one of the residential areas in Tokyo Bay with high condominiums and green parks. Although, Harumi is still one of the popular places in Tokyo Bay. For instance, Olympic village was constructed in this island for Tokyo 2021. Various people around the world gathered in this one small island. The potential of Harumi is still yet to be enhanced.

Site Information

Odaiba The history of Odaiba has begun in 1853 when Japan was governed

by Tokugawa shogunate. In that moment, the shogunate was politically unstable because of the dispute between “kaikoku (the open country)” wing and “Joi (the expulsionist)” wing. “Daiba” was constructed to protect Edo-city from invasion. Since the city change its name from Edo to Tokyo, the importance of daiba gradually decreased thus they were converted to other types of usage such as parks and shipyards. Moreover, after the WW2, most of those daiba were reclaimed from above and disappeared. Those new reclaimed land are the area that is called “Odaiba” these days.

Currently, Odaiba is one of the center of “Tokyo Waterfront City”, consist of several huge commercial buildings and office buildings,

Masterplan of Harumi 6

Harumi Connection

Introduction Proposal for the masterplan design was done by in groups which are devided by their planning area.

In this part, one group from Waseda University planned a masterplan of Harumi area. The proposed masterplan is: •

Group 1: Harumi Connection

The proposal is consisted of five parts; concept, vision, SWOT analysis, masterplan, and Specific plan.

Harumi Connection

G1.1 Concept Improving the Connectivity of Harumi Residents The connectivity of Harumi island will be highly improved by our new transportation system, which enhances both internal and external connections of the island. Current automobileoriented transport developed on the island causes heavy traffic and negatively impacts surrounding environments.

Therefore, we aim to propose island residents several means of transportation which will not rely on automobiles but utilize ferry, slow tram, and share-cycle networks, creating a wellconnected and eco-friendly city.

G1.2 Vision Building a well-connected city with "Harumi Connection" We propose "Harumi Connection", or "Haru-Cone" for short, which is a transportation hub that includes both internal and external connections within and to the island.

Our vision of Harumi island with "Haru-Cone" consists mainly of three parts. First, we envision an island that is well-connected both internally and externally. Second, we envision an island that is loved by its resident and those residents will like spending their time on the island. Third, we envision an island that is prepared for future natural disaster such as high-tides and rising sea levels.

G1.3.2 SWOT -WeknessLack of Transportations The lack of transportation translates into bad west to east connectivity, and it is also difficult to get in and out of the island for non-motor vehicles. Currently, it takes 30min to walk from east to west, and there are only 5 gates connecting to outside which are all for motor vehicle transport; train stations are all located outside of the island, thus there is a heavy demand on the local bus network.

walkways, and every other city element in Odaiba is “mega scale” compared to those in other areas. However, this “Bigness” is causing a lack of liveliness, because people are so small compared to the scale of infrastructures which make the place look inactive.

Therefore, our concept for the future Odaiba masterplan can be summarized in two parts.

Inside Out

1. Utilize Odaiba’s characteristic, “Bigness” ([Stay Mega]) 2. Create a lively city from every direction ([Inside Out])

Stay Mega, Inside Out: Concept

27

G2.2 Vision City with "Mega Scale" Human Activity Our vision of future Odaiba is a city where human activities would spread “mega scale”. We redesigned two potential infrastructures that are currently not utilized enough and have capability of adapting human activity to a mega scale city; Yurikamome railways, and West Promenade.

The city masterplan with these two redesigned infrastructures expands human activities broadly through the entire city and create beautiful townscapes.

28

Stay Mega, Inside Out: Vision

G2.3 SWOT Analysis G2.3.1 SWOT -StrengthConvenient Transports Odaiba is a place well-connected by public transit. This includes the Yurikamome, buses, and ferries. These transports connect users to popular spots in Tokyo.

Plaza; A Cross Point of Pedestrian Axes The plaza is an intersection of two axes running from north to south, and from west to east.

Abundant Entertainment Facilities The area contains a lot of entertainment facilities that people can enjoy.

Stay Mega, Inside Out: SWOT Analysis

29

G2.3.2 SWOT -WeknessHuge Rail and Roadways Dividing Blocks The area is divided by Yurikamome railways and highways which are huge. These infrastructures are preventing groundlevel connectivity between blocks.

Scale Mismatch The scale of land use and facility volume are mismatched to the scale of users. Since people are much smaller than the surrounding environments, there are spaces not used efficiently.

30

Stay Mega, Inside Out: SWOT Analysis

G2.3.2 SWOT -OpportunityUrban Redevelopment in Surrounding Areas Tokyo bay area is one of the hot spots of urban redevelopment.

It includes areas such as the Tokyo CBD area and Tsukiji area in the north, and Aomi area in the south.

Accessibility from Foreign Countries Odaiba is connected to theTokyo International Airport (HND Airport) with both land and sea. It is possible for visitor from the airport to go to Odaiba directly by train, automobile, and ferry.

Stay Mega, Inside Out: SWOT Analysis

31

G2.3.3 SWOT -ThreatA Decline in Visitors The number of people visiting Odaiba has been decreasing in the past five years; the Covid- 19 pandemic had an impact on its tendency. Most of the facilities in Odaiba are steadily decreasing in attractiveness.

32

Stay Mega, Inside Out: SWOT Analysis

G2.4 Masterplan G2.4.1 Strategies There are two strategies for our masterplan.

Utilizing Facilities’ Backspace as Another Façade

Turn buildings' back space into face

To develop the plaza in West Promenade, we planned to build some facilities surrounding the plaza to add convenience to the city. The plaza needs to be lively as a center of the city thus we design each building and their backspace as another façade which will be a necessary elements of good townscape.

Walkable City

Mega scale but walkable

Enable people to travel easily between buildings. Moreover, to enhance the city’s walkability “mega scale”, we utilize existing infrastructures such as the Yurikamome railways as a new pedestrian deck which will enhance accessibility and provide pedestrians great waterfront view.

Stay Mega, Inside Out: Master Plan

33

G2.4.2 Block Plan Commercial Axe and Educational Axe There are two axes running through Odaiba and each has its own features. For instance, most of the facilities located in the north-south axe are educational facilities such as museums, laboratories, and schools. On the other hand, commercial facilities such as shopping centers and entertainment facilities mainly locate in west-east axe.

Therefore, we integrated these two axes to the block plan of the plaza and match facilities to the axe they are located.

34

Stay Mega, Inside Out: Master Plan

G2.4.2 Block Plan Facilities We placed residice, office and commercial facilities in the northern part of the plaza. On the other hand, art facilities, theater, sport facilities and transportation core are placed in the southern part. The placement simply follow the commercial axe and educational axe.

Stay Mega, Inside Out: Master Plan

35

G2.4.2 Block Plan Building Design Sunlight movement is considered when deciding the height of the buildings surrounding the plaza. The buildings on the south-side of the plaza are lower while the buildings on the north-side are higher which makes the plaza in its entirety get enough sunlight. Moreover, the façades of the buildings are designed taking the shape of the plaza, the view toward the axes and Flow line of the people are taken into consideration.

36

Stay Mega, Inside Out: Master Plan

G2.5 Yurikamome Linear Park G2.5.1 Background Information Yurikamome Line The Yurikamome line is the monorail transportation running through the Tokyo Bay area. We evaluate the Yurikamome line compared to other transportation system running through Tokyo Bay area based on three categories: cost performance, transportation capacity, and disturbance of urban environment.

-Cost PerformanceThe fare of Yurikamome line is ¥230 / km. This is much more expensive compared to other transportation systems.

-Transportation CapacityThe capacity of Yurikamome line is 416 people (52people / 1 car) while the Rinkai line is 1560 people (156 people / 1 car). The capacity of the Rinkai line is almost four times larger than the Yurikamome line.

-Disturbance of Urban EnvironmentThe monorail track and its pier are disturbing the view especially from the people on the ground level.

Stay Mega, Inside Out: Yurikamome Linear Park

37

G2.5.2 Proposal Yurikamome Linear Park Here we present “Yurikamome Linear Park” ; the pedestrian sky garden which redesigned existing Yurikamome railway.

Yurikamome line has low capacity as transportation system and disturbing urban environment, however the railway could still utilize as observation platform that provides great views. Therefore, we redesigned railway from Tokyo Cruise Terminal sta. to Ariake sta. as a pedestrian sky garden and new transportation networks as substitution of Yurikamome line in the area.

38

Stay Mega, Inside Out: Yurikamome Linear Plan

G2.5.2 Illustrative Plan Great View from the Platform Yurikamome Linear Park will fully utilize Odaiba's great feature which is its scenery. From the platform, people could view beautiful Tokyo Bay with city skyline or massive buildings of Odaiba area which is a symbol of Odaiba's "Bigness".

Stay Mega, Inside Out: Yurikamome Linear Plan

39

G2.5.4 Features The Yurikamome Linear Park would have three key features.

BEFORE

-View to Mega cityThe park provides users provide with a perspective of mega scale. People could enjoy Odaiba’s “bigness” fully and freely.

-Ocean ViewAs the park utilizes the railway, it provides people with an ocean view which could not be fully seen from ground level before.

G2.5.5 Substitutional Transportation Networks Maintain Residents' Accessibility

Existing Yurikamome Plan

These are substitutional transportation networks of the Yurikamome line. More than 50,000 people use the Yurikamme from Tokyo Cruise Terminal sta. to Ariake sta. We planned a new loop-line bus network that supports people who use those stations often. The loop-line bus network will be connected to other transportation networks which enhances accessibility.

Future Yurikamome Plan

Stay Mega, Inside Out: Yurikamome Linear Plan

41

G2.5.6 Linear Park and Tourist Destination Linear Park Connects Whole Odaiba The park enables people to visit popular tourist destination smoothly. The park will be a new common space. I would not only be a tool to enjoy Odaiba’s “bigness” but also play a role as a “connector”, uniting each place into one Odaiba.

Group 3 Enhance the Appeal of the Land Karin Tanaka (Yaguchi Lab) Mizuho Honda (Yaguchi Lab) Kei Hiraguri (Yaguchi Lab)

44

Enhance the Appeal of the Land

G3.1 Concept Utilize the Rich Greenery and Waterside Landscape Since Odaiba is an artificial land, it has been developed as an entertainment island formed by several large commercial facilities with rich greenery and waterside landscape. However, those landscape features are not currently utilized effectively thus visitors are confined inside the facilities and not likely to walk outside.

Our aim is to fully utilize those existing landscape features and rebuild the island where visitors could enjoy both the indoor and the outdoor.

Enhance the Appeal of the Land: Concept

45

G3.2 Vision Creating Lively City We redesigned the current waterfront, parks, commercial facilities and residential zones so that various people can enjoy both the indoor and the outdoor. Moreover, we planned a mobility network that connects them, thus people could travel smoothly between places. Therefore, Odaiba will be livelier by fully utilizing its facilities and landscape features.

46

Enhance the Appeal of the Land: Vision

G3.3 SWOT Analysis G3.3.1 SWOT -Strength① Good Views on the Axes No such tall buildings interrupt the view seen from plaza.

Famous spots in Tokyo such as the Tokyo Tower and the Rainbow Bridge can be seen from close.

〇 Current view

× If buildings get higher

② Large Green Spaces The area contains a lot of greenery especially on the seaside. ③ Many Share-cycle Ports People can rent share-cycles from any port in the area. ④ Buildings Connected Each Other by Decks People can walk across buildings smoothly.

Enhance the Appeal of the Land: SWOT Analysis

47

G3.3.2 SWOT -Wekness① Distanced buildings It is a long way walk for pedestrians to travel between buildings. ② Highway Dividing the Site The Metropolitan Expressway is running through the site horizontally.

③ Less Ocean View from the Waterfront Due to the artificial waterfront constructed higher than sea level, the view from the sea-side doesn’t actually include the ocean a lot. ④ Limited Attractiveness Most of the visitors are attracted to the place only by its entertainment features, not its “place”

48

Enhance the Appeal of the Land: SWOT Analysis

G3.3.2 SWOT -Opportunity① Water Transportation Network The site is connected to Asakusa by water transportation network. ② Covid-19 Due to Covid-19, utilizing outdoor open spaces is valued as a prevention for the spread of infectious disease. ③ High Daytime Population Office workers gather here from all around the Tokyo Metropolitan area. ④ High Demand on “Compact City” Compact city is convenient for residents and enables them to live in a small living space.

Enhance the Appeal of the Land: SWOT Analysis

49

G3.3.3 SWOT -Threat① Possibility of Constructing Tall Buildings Since Odaiba is an urban redevelopment area, there is a possibility of constructing massive buildings which affects its townscape. ② Container Transport as a Top Priority The surrounding area, including Odaiba, is a hub for international trade. Therefore, its function of serving as an international port is a high priority in the area’s development. ③ No Originality in Commercial Facilities Same types of commercial facilities which are massive and multifunctional have been constructed in other regions of the Tokyo Metropolitan area. Odaiba should focus on its original features to differentiate itself from other commercial districts.

G3.5 Redesigning the Plaza G3.5.1 Masterplan Volume Layout We focused on creating a lively atmosphere and preserving the openness of the plaza at the same time.

In order to achieve this, we set a volume method to control the level difference between plaza and buildings; the closer the buildings are located from plaza, the lower their height becomes.
