New Chapter Begins: Celebrating 50 Years of ECO-INTER K.K. and Introducing SxS Partners

Dear Friends and Partners,



We are thrilled to share an important milestone in our journey—one that signifies half a century of dedication, innovation, and resilience. In early 2023, we celebrated the 50th business anniversary of ECO-INTER K.K., a journey that has taken us from our humble beginnings in 1973 as a media content and electric engineering services company to

our exciting transformation in September 2023 into SxS Partners.


Our Journey: 1973 to 2023


Our story began in 1973 when an inventor and small business pioneer envisioned a company that would leave a lasting impact on the new media technologies market.

ECO-INTER K.K. was born as a media content services equipment company, driven by a passion for creativity and a commitment to excellence in the field of new media tools

( imaging electronics ). Over the years, we honed our sales skills, expanded our horizons, and adapted to the evolving needs of our clients.


A Shift Towards Japan Market Entry and Business Development


In 2018, recognizing the dynamic changes in the global business landscape and our unwavering dedication to excellence, we embarked on a strategic shift. Our new leadership refocused our efforts on providing comprehensive Japan market entry and business development services. This decision allowed us to leverage our deep understanding of the Japanese market and our local network to assist businesses in successfully establishing themselves in Japan.


Introducing SxS Partners: A New Brand for a New Era


As we marked our 50th anniversary earlier this year, we felt it was time to embrace a new identity that better reflects our evolving mission and vision. In September 2023, we proudly introduced ourselves as SxS Partners—a name that signifies "Solutions x Service."

This new identity symbolizes our commitment to collaborative innovation and our dedication to delivering solutions that make a positive impact on businesses and communities.


What to Expect from SxS Partners


With our new identity comes a renewed sense of purpose and a stronger commitment to our core values. As SxS Partners, we are dedicated to:


Strategic Partnerships: Building strong partnerships with clients, government agencies, and businesses to facilitate seamless market entry and sustainable business development in Japan.


Cutting-Edge Solutions: Continuing our tradition of innovation by providing state-of-the-art solutions that drive growth and success in the ever-changing global market.


Customer-Centric Approach: Upholding our commitment to excellence in customer service, ensuring the success of our clients is at the forefront of everything we do.


Global Impact: Expanding our reach to make a meaningful global impact through our services and solutions.


Thank You for 50 Years of Trust and Support


We extend our heartfelt gratitude to our esteemed clients, partners, and dedicated team members who have been instrumental in our success throughout this incredible journey. Your trust and support have been the driving force behind our growth and evolution.


As we embark on this new chapter as SxS Partners, we look forward to the exciting opportunities and challenges that lie ahead. Together, we will continue to build a future that is driven by innovation, collaboration, and sustainability.


Join us in celebrating 50 years of excellence and in embracing the limitless possibilities of the future.
