About EIDAI Optical
A direct path to eyewear manufacturing in Japan.
EIDAI is based in Sabae and serves brands that want to turn a defined eyewear design into a product made in Japan.
Our role is simple: understand the design, clarify the production path and make the product with care.

Sabae, Japan
We work from one of Japan's most recognized eyewear manufacturing regions.
What EIDAI brings to an eyewear project.
The company is focused on making the route from design to production easier to understand and easier to manage.
A manufacturing point of view
Design decisions are considered in relation to tooling, machining, components, finishing and assembly.
Two core capabilities
Injection-molded frames and acetate CNC manufacturing form the production foundation.
Development before production
3D design and prototypes help resolve important questions before manufacturing commitments are fixed.
A Sabae manufacturing base
Projects connect directly to a company working from one of Japan's recognized eyewear production regions.
Four principles guide the work.
The purpose is straightforward: preserve the design intent while making the production path technically clear.
-
Begin with the product
Understand what the brand wants to make before selecting equipment or describing a process.
-
Resolve questions early
Use technical review and prototypes to address structure, scale and manufacturing questions before production.
-
Keep manufacturing connected
Treat molding or machining, finishing, assembly and inspection as parts of one project.
-
Communicate directly
Create a practical conversation between the brand, the design information and the factory work required.
Who EIDAI is built to work with.
The strongest fit is a brand or product team that values Japanese manufacturing and wants direct discussion around a real eyewear design.
Established eyewear brands
Teams with a mature design seeking a Japanese manufacturing route.
Product developers and designers
Teams that need to connect drawings, CAD data or reference samples to production decisions.
Overseas sourcing teams
Buyers looking for direct access to injection molding or acetate manufacturing in Sabae.
A productive first conversation is concrete.
Share the product you want to make, the current design status and the manufacturing support you need. The discussion can then focus on the next real decision.
- What you want to make
- Product type, frame concept and intended construction.
- What you already have
- Sketches, drawings, CAD data, physical samples or material references.
- What you need next
- Development, prototype, molding, machining, finishing or full production support.
