What Our Partners say about J21

By analyzing the visitors’ statistics on the JPEGmini.com website, we found out that access from Japan was very significant. We knew that our business in Japan would grow only if we had a local representative that could interact with customers in their own time zone, language and culture. We found Japan21 to be the perfect partner: They built a significant business in Japan for us, and they provide great customer support. We recommend their services to any company wishing to grow their business in Japan.
Dror Gill, CTO, Beamr Imgaging Ltd.
We started our business relationship in 2007 to do Car and Mobile phone interoperability service together worldwide. The reason was simple, NextGen needs a Japan partner to do the business worldwide and Mike Kato (CEO of J21) was my business partner when we did WW OEM biz for Motorola.
Result is excellent, NextGen is now the largest Car-Smartphone interoperability service company and Mike is on Nextgen board member. Thanks to J21 for the continuous and consistent service in such long period. NextGen team has been enjoying day to day joint work of J21.
