With the completion of TUGBOAT SUITE in 2025, TUGBOAT TAISHO has now reached its final form.

Located on the left bank of the Shirinashi River in Taisho Ward, Osaka, TUGBOAT TAISHO is a waterfront commercial complex that has developed in phases over nearly a decade. The main commercial area was completed in 2020, while the adjacent accommodation project, TUGBOAT SUITE, was temporarily suspended due to the COVID-19 pandemic. Construction later resumed, and its completion in 2025 marked the completion of the entire development.

The project began in 2016, when our proposal, developed together with the facility operator, was selected through a public competition initiated by Taisho Ward. The aim was to create a lasting source of activity in response to population decline and to revitalize the area through greater use of the waterfront and water transportation.

Osaka is a city shaped by countless small restaurants, bars, and shops. Each has its own character, atmosphere, price range, and relationship with the neighborhood. Individually, they create small pockets of activity; collectively, they form the identity of an area. Importantly, these places are not created according to a single set of rules or a unified design language. Their differences are precisely what give the city its richness and warmth.

We wanted to bring this quality into a commercial development. From this ambition emerged the central concept of the project: “to create a commercial facility that does not feel like a commercial facility.”

Achieving this required us to reconsider not only the architecture itself, but also the conventional systems through which commercial facilities are developed and operated.

One of the key issues was construction cost. For small independent businesses, high rents and strict tenancy conditions often make entry into commercial facilities difficult, and construction cost is one of the major factors behind these high rents. We therefore approached cost reduction not simply as a matter of economy, but as part of the design strategy itself.

By simplifying the building structure, minimizing finishes, establishing target costs for each stage, continuing construction discussions and cost negotiations until shortly before work began, and dividing the work among specialized contractors, we were able to substantially reduce the overall construction budget. Lower construction costs made it possible to set lower rents, allowing the operator to invite distinctive independent businesses that might otherwise have been excluded from a conventional commercial development.

We also rejected the usual system of strict tenant design control. Streets and neighborhoods are not created through rules that demand visual consistency from every shop. Their character emerges from the coexistence of different tastes, materials, lighting, colors, and ways of making space.

At TUGBOAT TAISHO, only the minimum requirements necessary for structural safety, waterproofing, and legal compliance were established. Beyond these basic conditions, each tenant and its design team was given considerable freedom. The result was a collection of highly individual spaces, each with its own atmosphere. Within the food hall, graphic neon signs were introduced as a loose visual framework connecting these different identities.

Another essential aspect of the project was collaboration with Taisho’s local manufacturing industry. Taisho has long been one of Osaka’s major industrial districts, with numerous factories and workshops possessing highly specialized fabrication skills. We wanted to practice a form of local production within architecture itself, and wherever possible, components required for the project were developed and fabricated by manufacturers in the surrounding area.

Handrails, staircases, deck structures, steel doors and fittings, signage, wire ropes, and even industrial drums were conceived and produced together with local factories and incorporated directly into the architecture. Working directly with these manufacturers helped reduce procurement costs, supported the local economy, and gave the factories an opportunity to demonstrate their craftsmanship within their own community.

Through this process, the architecture became closely connected to Taisho’s identity as a district of manufacturing and making.

Through TUGBOAT TAISHO, we came to understand design as only one part of a much larger process—and as one of the catalysts that can initiate change. The character of the project was shaped not simply by its form, but by the way the operator, designers, contractors, tenants, and local manufacturers worked together to determine what was truly necessary and how those elements should be assembled.

Rather than designing a commercial facility as a finished object, we sought to design the conditions through which the character, energy, and diversity of a city could emerge.
