Is "If it's not illegal, it's okay"? The Ethics and Systems of Re-designing Fish-Shaped Soy Sauce Containers
Using Heliograf and Asahi Sogyo as Case Studies
When "Cute Daily Necessities" Become a Trigger for Controversy
The fish-shaped soy sauce container is an icon that has long been cherished within Japanese bento culture. The original creator is Asahi Sogyo in Osaka, and the company's product name is "Luncharm." The company officially states that "the fish-shaped plastic containers that come with bento boxes are our products," and it is noted that they were developed by the founder, Teruo Watanabe.
Meanwhile, the Australian design studio Heliograf has developed a lamp called "Light Soy" based on this "fish" motif, and further positions its product in a context that criticizes the environmental impact of disposable fish packets. Their official store and blog highlight the "lamp inspired by the iconic fish soy sauce container" and the "environmental issues of fish packets."
In addition, they also present proposals for alternative containers using bio-materials, offering "options for the future."
What arises here is a gap between systems (copyright, design, trademark, unfair competition) and ethics (respect for the source, control over the narrative).
Especially in Western venture culture, there is a strong practical sense of "if it's legally safe, go for it," and it is easy to prefer a narrative design that overwrites the situation with social justice (sustainability) to stand on the "future side."
The Original and the Reinterpretation
Clarification of the original: Asahi Sogyo clearly states the history of Luncharm and that "fish-shaped soy sauce containers = our products" on its website.
The narrative of the reinterpreting side: Heliograf writes in its product pages and explanations that it is "inspired by the iconic fish soy sauce container" and a "symbol of environmental impact."
Social tailwind: In September 2025, South Australia became the first in the world to add fish-shaped soy sauce containers (under 30ml, with caps, etc.) to its list of prohibited items. In the context of environmental regulations, the composition of "fish packets = villain" was also reinforced institutionally.
How to Interpret the "Gray Area Leaning Toward White"
Copyright: The shape of functional daily necessities is often weakly protected as artistic works.
Design rights: Even if it was registered in the past, it is highly likely that it has expired (maximum 25 years). After expiration, monopoly is difficult.
Trademark: Trademarking the shape itself is generally a high hurdle.
Prevention of unfair competition: If you avoid "confusion" with a light that has a different purpose and do not create an "official-like" appearance, the hurdle for being certified as illegal increases.
In short, contrary to the intuition that it is "intensely similar," it is easy to construct a "gray area leaning toward white" in form. Heliograf reinforces its legitimacy with the change in use from "container to lighting" and the narrative of public good as "environmental awareness." The choice of words in the product description is also limited to "inspired," avoiding the composition of misidentification with a specific manufacturer.
Connecting to the parties involved: Is "existence" enough for alternative containers?
The fact that Heliograf is presenting alternative bio-container proposals is important. However, existing and being effective for the structure are different issues. If we are to truly reduce environmental impact, the order should originally be like this.
Access to and dialogue with the sources of the problem (manufacturing, distribution, and hygiene standards)
Operational design for material conversion, collection, and refilling (cost and hygiene requirements)
Joint implementation and pilot testing with industry players
Disclosure of the process and results (including failures)
If you present an "alternative" without making these visible, you create room for it to be perceived not as an "implementation roadmap," but as a "narrative justification device." In other words, there is a danger that it remains a "declarative design" lacking a sense of stakeholder involvement.
Other problems caused by denying existing businesses
Developing an alternative container business is, in itself, free. However, if you justify it by uniformly labeling existing container culture and manufacturing/distribution systems as "guilty" and pushing them into a morally inferior position then the problem expands from the environment to the redistribution of cultural value and market dominance. If you incite a linear "old equals bad / new equals good" narrative in the name of environmental justice,
the costs of dialogue and transition become invisible, and ultimately, it leans toward a "re-domination of the narrative" in the absence of the stakeholders.
Who holds the "right to speak"?
What should be questioned here is not just the line between legal and illegal.
Respect for cultural origins: Explicitly stating the original, crediting sources, sharing context, and considering collaboration or licensing.
Avoiding binary narratives: Consideration to avoid inciting a simple conflict of "original equals bad" and "redesign equals good."
Stakeholder involvement: In discussions about environmental impact, do not just villainize the "traditional side," but also pay attention to improvement efforts and transition costs.
South Australia's regulations set the "little fish" as a symbolic target. When systems provide support, it is easy for a linear narrative of "cultural icon to environmental villain to new design as savior" to take hold.
But the reality of operations (supply chains, hygiene, costs, and transition logistics) is not that simple.
Piggybacking or legitimate re-editing? Establishing evaluation axes
Degree of differentiation: Is the formal reinterpretation sufficient in terms of proportions, materials, size, function, light/electronics, etc.?
Communication: Does the product page or FAQ avoid confusion and clearly state respect for the original and the educational context?
Ethics design: Are there circuits for "building relationships" such as credits, joint promotion, licensing, or giving back?
Social impact: Is the contribution to regulations, public opinion, and industrial transition substantial, or does it end with the consumption of a "justice package"?
Viewed through these axes, Heliograf's strategy can be evaluated as choosing a safe zone in terms of regulations while preempting the public opinion narrative, all while leaving room for "respect and collaboration" on the ethical side.
How to bridge the "perceptual gap" between Japan and the West
In Japanese business practice, "prior confirmation/agreement with the original manufacturer" is a matter of "courtesy" and an "infrastructure of trust."
On the other hand, Western activist-style design is strongly driven by ideas such as "free re-editing of cultural symbols," "if it's legally safe, go for it," and "litigation is part of the process." Herein lies the difference in the priority of systems and ethics.
That is why the original creator (Asahi Sangyo) has three possible strategies.
Reclaiming the narrative: Visualize the origin, history, and improvement plans in multiple languages on the official website and products to regain control of the story.
Proposing co-creation: Create a roadmap for the development of a sustainable version of Luncharm and a collection/refill scheme, and open a window for collaboration.
Clarifying boundaries: Externally present guidelines for trademarks and labeling, as well as requirements for "avoiding confusion" (and design a licensing framework if necessary).
To go beyond "it's good because it's legal"
It is certain that re-design is a device for cultural renewal. The question is, on whose history, and with what kind of respect and relationship design,one does it.
The fish-shaped soy sauce container is not just a consumable item, but the very accumulation of postwar Japanese daily culture and small-to-medium manufacturing. The Heliograf case exposed the distortions at the intersection of law and ethics, activism and industry, and narrative and ownership.
The minimum condition for standing on the "future side" is the visualization of origins and a circuit for dialogue. "Overwriting justice" while neglecting that is dangerously close to the usurpation of cultural credibility.
Absolution through "light" and the design hegemony of the future
Redesign often wears the guise of rescuing the "past," but in reality, it can slip into
a political act of rewriting the control of meaning.
The fish-shaped soy sauce container has long been overlooked as a "small daily necessity."
However, the moment it is redefined as a "symbol of environmental destruction," it is pushed into a "guilty past,"
and those who convert that guilt into light prepare to claim the title of "legitimate guide to the future."
Here, I want to leave one more probing question.
Developing alternative containers as a business is, of course, free.
But if, in order to establish its legitimacy, one repositions existing container culture and the manufacturing and distribution that still continue today as a "morally inferior"
"environmentally sinful past," then it goes beyond the discussion of environmental improvement and looks like
a game of redistributing cultural value and market leadership.
Does "the first entity to turn a sinful past into light" also simultaneously acquire the right to call itself the "next legitimate version" of that symbolic shape?
When the time finally comes when an "environmentally friendly new fish-shaped container" is truly needed,
will the one holding that "correct form of the future" be the original creator?
Or will it be the side that rearranged the meaning of the symbol first?
Light Soy can be both a light and a quiet declaration.
"From here on, the future of the fish shape begins with this story."
Is it a light for the environment, or a prelude to the re-ownership of a symbol? There is no need to rush to a conclusion. However,
a structure that can be read that way is certainly here.
