Kingyobu in Osaka: Turning Old Phone Booths into Living Goldfish Aquariums

Introduction

In the busy streets of Osaka, Japan, something unexpected appears between modern buildings, traffic, and neon lights. What once looked like ordinary, forgotten public phone booths has been transformed into glowing underwater worlds filled with swimming goldfish.

This creative public art project is called Kingyobu, and it turns abandoned urban objects into vibrant living installations. Instead of removing the old phone booths completely, artists have reimagined them as miniature aquariums, bringing color, movement, and life back into forgotten spaces.

The result is both surprising and calming, offering a moment of beauty in the middle of a fast-moving city.

The Idea Behind Kingyobu

Kingyobu, which can be loosely translated as “Goldfish Club,” is a Japanese art group known for its imaginative approach to public space.

Their goal is to transform overlooked or abandoned structures into something meaningful and visually striking. In this case, they chose old public telephone booths—symbols of a past communication era that have become largely unused due to mobile phones.

Instead of letting these structures decay or disappear, they were repurposed into transparent aquariums filled with water and goldfish.

This transformation turns an outdated object into a living artwork.

From Phone Booths to Aquariums

The visual contrast is one of the most powerful aspects of the installation.

Phone booths, once used for private conversations in public spaces, are now filled with clear water and moving fish. The rigid, metallic structure becomes a soft, fluid environment where life flows freely.

Inside each booth, goldfish swim slowly through the enclosed space, creating a peaceful underwater scene that feels completely disconnected from the surrounding urban environment.

The glass panels allow passersby to view the installation from all sides, turning the booth into a small window into another world.

Symbolism of Goldfish in Japanese Culture

Goldfish are not chosen randomly for these installations.

In Japanese culture, goldfish are often associated with luck, prosperity, and good fortune. They are commonly seen in festivals, decorative art, and traditional celebrations.

By placing goldfish inside abandoned phone booths, the artists combine cultural symbolism with modern urban decay, creating a contrast between past and present, tradition and technology.

The result is a meaningful visual metaphor that connects everyday life with deeper cultural ideas.

A Blend of Nostalgia and Modern Art

The use of old telephone booths adds another layer of meaning to the project.

These booths represent a time when communication required physical presence and effort. Before mobile phones, people had to step into these small spaces to connect with others.

Now, instead of carrying voices, they carry life in the form of swimming fish.

This shift creates a strong sense of nostalgia, reminding viewers of how quickly technology changes the way humans interact.

At the same time, it shows how old objects can be reimagined through creativity rather than discarded.

Urban Spaces Reimagined

One of the most striking aspects of Kingyobu’s work is how it changes the way people experience the city.

In a dense urban environment like Osaka, most objects are functional and practical. Streets, buildings, and infrastructure are designed for efficiency.

The goldfish phone booths break that pattern.

They introduce something unexpected, something that has no practical purpose but creates emotional impact instead. People walking by are often surprised, curious, or even stopped in their tracks.

This interruption of routine is part of what makes the artwork so powerful.

The Experience of Passersby

For many people, encountering a goldfish-filled phone booth is a completely unexpected moment.

A simple walk down the street suddenly turns into a visual experience that feels almost dreamlike. The movement of the fish contrasts with the stillness of the booth and the speed of the city around it.

Some people pause to take photos, while others simply observe quietly for a moment before continuing on their way.

These brief encounters create small emotional breaks in daily life, adding a sense of calm and wonder to an otherwise ordinary environment.

Public Art and Community Engagement

Kingyobu’s installations are part of a broader tradition of public art in Japan that aims to engage everyday people rather than isolate art inside galleries or museums.

By placing artwork directly in public spaces, the artists ensure that anyone can experience it without barriers.

There is no need for tickets, schedules, or formal settings. The art exists as part of the city itself.

This accessibility helps bring art into daily life, making it more inclusive and spontaneous.

The Relationship Between Nature and Urban Life

The goldfish installations also highlight the contrast between nature and urban environments.

Cities are often associated with concrete, noise, and constant movement. Nature, on the other hand, is associated with water, life, and calmness.

By placing living fish inside a man-made structure in the middle of a city, Kingyobu brings these two worlds together in a single visual space.

This combination encourages viewers to reflect on the relationship between human development and the natural world.

Temporary Beauty in Changing Spaces

One important aspect of these installations is their temporary nature.

Like many forms of street art, they are not permanent. Over time, installations may change, move, or disappear depending on location and conditions.

This temporary quality adds to their emotional impact. Knowing that the artwork may not always be there makes the experience more special in the moment.

It emphasizes the idea that beauty can exist briefly and still leave a lasting impression.

Creativity in Everyday Objects

Kingyobu’s work demonstrates how creativity can transform even the most ordinary objects.

A phone booth, which most people might ignore or overlook, becomes something extraordinary when reimagined as an aquarium.

This transformation shows that artistic vision does not always require new materials or large-scale construction. Sometimes, it only requires a new way of seeing something that already exists.

A Message of Renewal and Imagination

At its core, the project carries a message of renewal.

Abandoned objects are not discarded—they are reimagined. Empty spaces are not ignored—they are filled with life and meaning.

This approach reflects a broader philosophy that values creativity, sustainability, and imagination in urban design.

It encourages people to see potential in places and objects that might otherwise be forgotten.

Conclusion

Kingyobu’s goldfish phone booths in Osaka are more than just visual installations. They are a poetic transformation of urban space, turning forgotten communication devices into living works of art.

By combining cultural symbolism, public engagement, and creative reuse, the project creates moments of surprise and calm within a fast-paced city environment.

It reminds us that even in the most ordinary corners of urban life, beauty can appear unexpectedly—and sometimes, all it takes is a little imagination to bring it to life.
