We custom-design
‘one-of-a-kind’ products
to match the customer’s ideal vision.

UNION holds around 90%
of the door handle market for Japanese hotels,
office buildings and cultural facilities, etc..
Architects and designers place great trust
in what we do.
One reason for this is that we can custom-create
products with total confidence.
We merge our abilities with the architect or
designer’s vision,
and carefully select
materials accordingly.
Based on their ideas and concepts, we can bring into reality a one-of-a-kind product
unlike any other in the world, using high-precision technology
and our wide selection of materials and finishes.
We can meet the customer’s ideal vision
even for a single one-off set.
We are proud to provide what can truly be called
‘haute couture door handles’.
