ODM Development of a Cordless Vacuum Cleaner
for Entry into a New Market

Major Domestic Home Appliance Manufacturer
We developed a cordless vacuum cleaner under an ODM contract to support a major domestic home appliance manufacturer’s entry into a new product category. We achieved a quick market launch by an integrated response from design and prototyping to mass production.
Background and Client Issues
The client manufacturer was planning to enter the vacuum cleaner market as a new business domain. Although the unique concept developed in the client’s company was attractive, there remained many issues in terms of feasibility and mass production. In particular, balancing “intuitive operability” with a “design that blends seamlessly into everyday living spaces” proved highly difficult, and the client was seeking a partner capable of driving the development forward.
Development Process and Yamada’s Contribution
We were involved from the concept feasibility testing stage, taking responsibility for the entire process —from design, prototyping, and evaluation to mass production— through repeated interviews with the client. Using a 3D printer, we repeated cycles of prototyping and testing to achieve a structure that provides light, comfortable operability while maintaining durability and vacuum performance. Additionally, while prioritizing exterior design, we pursued proportions that allow the vacuum cleaner to blend naturally into everyday living spaces. In addition, in cooperation with our own overseas plants and parts manufacturers, we simultaneously promote parts procurement and the ramp-up of mass production. By optimally balancing cost and quality, our integrated ODM framework successfully embodied the client’s concept in a product with strong market value.
Future Outlook
The finished vacuum cleaner received high acclaim in the market, leading to the development of successor and derivative models. Leveraging the achievements and expertise gained through this ODM project, we will continue working with our clients to take on new challenges in developing innovative product categories and creating next-generation products.
Voice of a Team Member

The major challenge in this project was transforming the client’s unique concept into a form suitable for mass production. During the prototyping stage, we struggled to achieve the desired operability, which led to multiple design revisions. However, by combining the team’s collective expertise, we ultimately found a breakthrough. The sense of accomplishment when mass production began and the finished product appeared on store shelves is something I will never forget. This project made me realize the immense responsibility involved in ODM development, and the experience of overcoming challenges together as one team became a tremendous opportunity for personal growth.

OEM Development of Plastic Household Goods
through Global Collaboration

Global Consumer Goods Manufacturer
In China, we design, prototype, and evaluate plastic molds and assembly equipment, then transfer production to our factory in Mexico for mass production of household goods for the North American market. Through close collaboration among our global teams, we completed the precision molds and successfully launched the product to market within a short timeframe.
Background and Client Issues
The client has been planning to introduce a new line of plastic household goods for the North American market. However, with limited experience in the design and mass production of high-precision multi-cavity molds, the main challenge lay in establishing global-scale manufacturing within a short timeframe. In particular, a smooth process —from mold design and prototyping in China to the transfer of mass production to Mexico— while maintaining consistent quality was required. Integrating process coordination and communication across multiple locations was also essential, making strong project management skills and an effective international collaboration framework key to success.
Development Process and Yamada’s Contribution
Based on the design drawings provided by the client, we created manufacturing drawings and established evaluation standards in Japan. Our factory in China then designed high-precision multi-cavity molds. After multiple rounds of prototyping and debugging in China to finalize high-precision molds suitable for mass production, we shipped them to our factory in Mexico, where additional rounds of prototyping and evaluation were conducted. The project was carried out under a global framework: The technical team in Japan managed overall coordination; the factory team in China handled design and prototyping; the U.S. sales team acted as the primary point of contact with the client; and the factory team in Mexico managed the ramp-up of mass production. Through seamless collaboration among these locations and by optimizing the balance of quality, speed, and cost, we successfully achieved mass production for the North American market within a short timeframe.
Future Outlook
Leveraging the expertise in global collaboration and precision mold development cultivated through this project, we will continue to take on mass production projects for OEM product development targeting overseas markets. Furthermore, we will establish an efficient international project model involving coordinated teams in China, Mexico, Japan, and the United States to further enhance the value provided to our clients.
Voice of a Team Member

The greatest challenge in this project was maintaining close coordination among the teams in China, Mexico, Japan, and the United States. Prototyping the multi-cavity precision molds required extremely fine adjustments, and we repeated multiple cycles of prototyping and debugging. By maintaining close communication and information sharing with these locations and working together to resolve issues, we succeeded in the ramp-up of mass production. This experience of delivering results within a short timeframe as a unified global team greatly enhanced our capabilities in global project management and problem-solving.

Product Planning for the Hapyson
× Tsumotoshiki Collaboration Series

Project leader Mr. Sakai is using his professional-level knowledge of fishing, a hobby, to drive the project forward.

Our Own Brand: “Hapyson” Products
We jointly developed products with Mitsuhiro Tsumoto, the leading expert in fish maturation (aging), aiming to shift the focus from simply “catching fish” to “catching and enjoying delicious fish.”
We made the high-end Tsumotoshiki practical and affordable, drawing significant attention from many anglers.
Background and Client Issues
Responding to the demand from anglers to enjoy their catch with better flavor for a longer time, we collaborated with Mitsuhiro Tsumoto, who is renowned for his unique “Ultimate Bleeding” technique.
Traditionally, fishing culture focused primarily on the act of catching, with little awareness of handling or taste. This project introduced a new concept “enjoying the fish you catch” and helped expand it throughout the fishing community. By commercializing the Tsumotoshiki —once a high-end method accessible only to a small group of enthusiasts— at an affordable price and with practical functionality, we contributed to a major shift in the mindset of many anglers.

10th new product: Rechargeable scale remover.

Development Process and Yamada’s Contribution
Through thorough interviews with anglers and experts, we transformed Mr. Tsumoto’s hand-drawn sketches into detailed engineering blueprints, repeating cycles of prototyping and evaluation.
A key creative element was the rigorous verification of “usability in real fishing environments,” which led to continuous improvements to meet professional-level demands.
Our ability to incorporate on-site user perspectives —rather than relying solely on desk-based design— was made possible through close collaboration between the product planning team, deeply familiar with fishing culture, and the engineering department. This was an achievement that would have been difficult for other companies to accomplish.
As a result, we successfully commercialized 10 products, significantly contributing to the creation of an environment where anglers can safely and deliciously enjoy their fish.
Future Outlook
The “Light for Anisakis Finding” became a hit product, with sales exceeding 100,000 units.
Its use has expanded beyond anglers to supermarkets, izakaya restaurants, fish markets, and conveyor-belt sushi chains, becoming an integral part of Japanese food culture. We succeeded in making the Tsumotoshiki, once expensive and limited to a small group of enthusiasts, accessible at an affordable price and with practical functionality.
Through the unified efforts of internal and external teams —from planning and design to prototyping and mass production —we successfully introduced new value to fishing culture: “enjoying the fish you catch deliciously.”

The Light for Anisakis Finding is a hit product, with sales exceeding 100,000 units.

Voice of a Team Member

During the planning and development process, we sometimes felt uncertain about whether the products would truly benefit anglers, and we also experienced several prototype failures.
Despite these uncertainties and failures, we continued to discuss ideas and innovate together with our colleagues until we brought the final product to life.
It was hard work, but the moment customers told us, “Thanks to this product, we can enjoy our fish more deliciously,” all our efforts felt worthwhile.
The experience of achieving this goal together with my team —sharing both struggles and successes— has been an invaluable learning opportunity that continues to fuel my pride and motivation in this work.
