Secure your Japanese market success

There is a big burden in finding Distributors when entering the Japanese market.
We will manufacture and assemble your medical devices
on your behalf in Japan, and if you already have a distributor,
we will deliver the product and solve technical problems when malfunction occurs.

Unlike conventional schemes, it would be unnecessary
for shipping back non-conforming products to your country
and you will also reduce the number of trips for sending your engineers to Japan.
By providing our logistic service for your products, you can reduce the total cost of a product.

When searching for a distributor, you must begin with Japan’s market research
and also perform due diligence on potential partners,
and as a certified manufacturer and seller in Japan,
Sanyo Seiko will provide you a comprehensive support until
the actual signing of a contract with the best suited distributor.
If necessary, we will be your distributor in Japan and sell your products on your behalf.

Moreover, if you already have a sales rep in place but are having difficulties
in providing maintenance and overhaul services,
we will provide the solution you have been seeking.
SANYOSEIKO will provide maintenance, overhaul and routine check-up duties in Japan
on your behalf for medical equipment that you have delivered to Japan.
With our dedicated service, you will be able to maintain your hard gained creditability
and provide security and safety to the users.
