Tokyo, Japan.
Tokyo is the capital of Japan and one of the world’s most populous metropolitan regions. The city is organized as Tokyo Metropolis, consisting of 23 Special Wards, 26 cities, 5 towns, 8 villages, and island municipalities. Tokyo functions simultaneously as Japan’s political center, economic engine, and global urban node, characterized by extreme density, extensive rail-based mobility, and highly differentiated urban experiences.
Population:
Urban(Wards): 9,950,913 people (2025)
Metro: 14,276,882 people (2025)
Area:
Urban: 627.51 km2
Metro: 2199.94 km2
Population Density:
Urban Average: 15,858 people/km2
Metro Average: 6,490 people/km2
Politics:
Tokyo Metropolitan Government (TMG) is the administrative organization of Tokyo. The Governor of Tokyo is elected to a four-year term by Tokyo residents and is responsible for the overall administration of the metropolitan government. As the capital of Japan, the TMG holds broader authority than most municipal governments, combining both prefectural- and citylevel responsibilities. TMG is responsible for urban planning, transportation systems, public education, disaster prevention, public safety, environmental management, water supply, sanitation, housing policy, and social welfare services. The TMG consists of multiple policy bureaus and offices responsible for metropolitan-wide governance, coordinating administration across wards, cities, towns, and islands.
TYPOLOGY STUDY
Tokyo, Japan : High-Density Building Typologies.
39F Residential high-rise tower
The thirty-nine-story residential high-rise tower represents an extreme response to land scarcity by concentrating housing vertically. While maximizing physical density, this typology largely separates residential life from the surrounding urban fabric through controlled access and internalized amenities.
14F Residential Social Housing
The fourteen-story residential social housing block emerged as a response to housing shortages.
Extensive shared spaces and collective circulation systems allow high population density to coexist with everyday social life.
4F Shop House /Apartments
The four-story shop house or apartment intensifies mixed use along street-facing plots, with commercial functions at ground level and multiple residential units stacked above. By increasing vertical density while preserving continuous street frontage, this type responds to rising land value without fully abandoning a human-scale urban fabric.
2 Story Shop House
The two-story shop house combines a ground-floor commercial space with a residential unit above within a compact footprint. This typology embeds everyday economic activity directly into residential life, maintaining close relationships between living, working, and the street.
Tokyo, Japan : Urban Void Typologies.
Small
side alley, mixed commercial uses
A 3-meter-wide side alley running parallel to the Nakamise shopping street near Kaminarimon, accommodating smallscale mixed commercial uses. Small objects extends to the alley, welcoming visitors.
Medium
Forecourt of Kanda Shrine, Open space for Life-cycle rituals and Collective festivals
Small-scale open space Surrounded by high-density residential neighborhoods, the forecourt of Kanda Shrine operates as a flexible civic space, accommodating both intimate life-cycle rituals and large-scale collective festivals, shifting between everyday use and periodic intensification.
Large
21_21 Design Sight Park, Everyday public use, art
Located within a park-like open space beside Tokyo’s high-rise fabric, 21_21 Design Sight operates as both a cultural anchor and an open-space node. Artistic activities activate the site while the surrounding plaza supports everyday public use, including walking, lingering, and informal gathering.
X-Large
Odaiba, Daily recreational use, large public events
Set within a reclaimed waterfront zone, Odaiba is structured around a major urban axis composed of pedestrian corridors, parks, and open plazas. Framed by high-rise buildings and integrated with light-rail infrastructure, the axis extends toward Tokyo Bay and the Rainbow Bridge, operating at a metropolitan scale. While accommodating daily recreational use and pedestrian movement, the space is also designed to absorb episodic intensification through large public events.

REWORKING DENSITY THROUGH FINE-GRAINED SYSTEMS
Taipei City
This project draws from Tokyo, where fragmented land ownership produces a fine-grained and vertically layered urban fabric through incremental development. Density, open space, and mixed-use programs are negotiated within small parcels rather than large-scale redevelopment.
In contrast, Taipei’s walk-up apartments achieve high density but lack open space, while contemporary tower developments introduce open space at the cost of urban intimacy and fine-grained social interactions.
Positioned between these conditions, this project proposes a rule-based framework supported by FAR incentives to guide incremental redevelopment. Through parcel aggregation, setbacks, mixed-use integration, and multi-level connections, density is redistributed beyond the ground plane.
The proposal aims to preserve and transform Taipei’s fine-grained urban structure, maintaining urban intimacy while integrating density and open space over time.
