Domohorn Wrinkle's New Packaging: A Sustainable Transformation

After 30 years, Domohoorn Wrinkle, produced by Saishunkan Pharmaceutical Co., Ltd., is set to unveil its redesigned product packaging on May 26, 2026. This innovative packaging is the result of a collaborative effort with Otsuka Packaging Industry Co., Ltd., showcasing a commitment to environmental sustainability. The transition to a paper-based blister packaging, made entirely from FSC® certified materials, marks a significant evolution in product presentation. The updated packaging, known as 'Musubi Box,' signifies a shift from a 'do not throw away' philosophy to one rooted in circularity.

A Commitment to Environmental Responsibility

Saishunkan Pharmaceutical, a company deeply connected to nature, operates under the belief that "Domohorn Wrinkle cannot exist without the power of nature." This core philosophy has driven the company to implement environmentally considerate solutions, ensuring the benefits of nature are appreciated and passed on to future generations. Among their initiatives is the upcycling of 'sansho seeds,' which previously contributed to significant waste, and incorporating endangered plant species into their materials to aid in seed conservation.

While the previous packaging used leftover thread from towel factories, the new 'Musubi Box' enhances environmental considerations significantly, transforming to a design that participates in forest conservation through the use of FSC® certified paper. This modern approach to packaging aligns with Saishunkan's aim of contributing to society through their products.

Understanding FSC® Certification

FSC® certification serves as an international standard that provides reassurance around the use of sustainable forest resources. By opting for FSC-certified products, companies like Saishunkan contribute positively to the conservation of biodiversity, the rights of local communities and indigenous populations, while also ensuring responsible resource management.

Balancing Sustainability and Quality

The new packaging aims to achieve key goals: CO₂ emission reduction and maintaining pharmaceutical quality.

1. CO₂ Reduction Goals: The transition will facilitate the removal of multiple plastic components, specifically the clear films surrounding pouches and caps. By utilizing FSC-certified paper to create an entirely paper box, Domohorn anticipates a 30% annual reduction in CO₂ emissions.

2. Safety and Access: Maintaining product integrity was paramount while designing the packaging. The structure allows for upright storage and employs a high-pressure sealing technique ensuring contamination is prevented. Comfort and ease of use were also taken into account, ensuring effortless opening while guaranteeing safety and product integrity.

'Musubi Box': A Symbol of Connection

The term 'Musubi,' reflecting the act of tying or binding, encapsulates the essence of the new design, indicating the connection it fosters between customers, communities, and ecological futures. This purposeful move towards sustainability transforms not only the product itself but also actively encourages customer participation in global forest conservation efforts, thus contributing to society at large.

The packaging is not just about reducing waste but actively promotes the use of circular materials and less dependency on fossil fuel resources. This strategic adaptation reflects Saishunkan's intent to evolve beyond mere products, establishing a robust model that helps shape a promising societal future.

The Collaboration with Otsuka Packaging

Founded in 1954 in Tokushima, Otsuka Packaging continues to innovate, striving to add value through functional and aesthetically pleasing product designs. Their recent focus on sustainability and reducing environmental impacts aligns perfectly with Saishunkan's principles, further enhancing their collaborative efforts in creating impactful packaging solutions. In 2025, Otsuka begins implementing a more sustainable management approach while consistently working towards advancing socially responsible solutions and demonstrating excellent business practices, as demonstrated by their recent achievement in receiving the ‘Silver’ medal from EcoVadis.

Together, both companies embody a commitment to delivering joy through packaging that resonates with consumers, driving forward the vision of a sustainable society. As they continue to refine their offerings, Domohorn Wrinkle looks to the future with optimism and a steady resolve to maintain its role as a leader in eco-friendly practices.
